Weird (new?) curve tracer on eBay?

Keith
 

Have you guys seen this? Looks sort of like a wannabe 577 knock off. This looks like a new offering, not one of those Chinese made Tek licensed things that were being discussed a while back here on the forum.

So this is not a real 577, but I wonder who is behind these?

Here is the link

Obviously this is not a real Tek anything....since it only weighs 19 pounds! 😂

Hi Keith,
You can trim the links by just including everything up to the "?", as I've done here:

https://www.ebay.com/itm/Circuit-Specialists-Transistor-Curve-Tracer-CSI4810A/383382496906?

It seems that some mobile phone links have all the extraneous tracking info included. Not posting from one I have no idea whether this is the case, or not.

Cheers,
Geoff.

Hey all,

Here is a link to the vendors site.

https://www.circuitspecialists.com/csi8410a_transistor_curve_tracer.html

I was familiar with the brand. I use their variacs in the lab. They are a Chinese reseller. From what I have seen the quality is hit and miss. But I have a limited sample size of exactly 4. The varices one analog and one digital. But I am not going to complain a 1000VA variac is $109.00 with a digital meter that is passably accurate for $119.00. It would be interesting to see how it stacks up. I am also curious what Vc tops out at, and power applied.

Hi Keith, et al,
This curve tracer is the same one Miguel Work spotted on eBay on 09/07/19. See (Message #159867)
There is one difference: The "Front Porch" is different. So they are even imitating Tek by making different Front Porch plugins for their Curve Tracer.
Both curve tracers have different company names on them so I think neither company made it. The manufacturer is an OEM who will sell to any company that buys them in quantity. This customer can then put their brand logo on it and add it to their line of test equipment.

  I have similar observations.   I have purchased three different pulse oximeters from "China, Inc."  to test them out and have on hand just in case we get sick, and they are all Identical, except for the branding.  They even came in the same exact box.  Same as well for head lamps for walking the dog.   Two or three different brands, but otherwise exactly the same.  The headband straps suck, but the lights themselves are excellent, and bright.

  It's an interesting business model.

   My observations with respect to Chinese made products are that their metal finishing (i.e. the ground surfaces of vises, milling tables) is not quite up to par.   The plastic cases are poor, and ill-fitted.  And their CMOS technology sucks, so that instruments have to turn off automatically in 30 seconds or they just kill the batteries.  That makes weighing scales and micrometers hard to use.  In sum, what the Chinese lack is a quality aesthetic - an attention to detail, decent plastics, and CMOS technology.

  BUT, in each case, they are improving.   Every time I buy something from China, it seems a little better made than the last product I bought.   It's a real boon for us electronics tinkerers and experimenters and repairers.     I have a Chinese three-terminal component tester I use all the time.  An LCR meter that's really nice, a really smooth X-Y table on my drill press.      Oh, and let's not forget PC boards.    10 for $10 and a week's delivery time from Taiwan.   I'm not sure I should even bother to keep my wire wrap stuff, nor all the chemicals I need to etch my own PC boards.  It's a waste of space at this point.  A couple years ago, in the context of getting young people interested in the hobby, someone here said it's a great time to get into electronics. 

   Anyway, sorry for continuing the off-topic thread, but it is at least partially relevant in that we all need to fix our gear at some point, and the resources available from "China, Inc." are pretty amazing.

Hi Dan, I have the same impression. After many years of retirement I started to play again with electronics, fixing the old oscilloscopes I have. From nearly zero I had to start populating my collection of components, and I was amazed at the rock bottom cost of them, mostly from China, which I mostly bought from Amazon. Sets of resistors, diodes, capacitors, transistors, all of acceptable quality. I needed a NPN transistor... ordered a set of 600 for $9.99... and had them in hand in a few days. It is really, really hard for me to resist the allure to install a little lab to design an build (for fun) any electronic instrument I fancy and start tinkering, experimenting. One reason I don't do it is because TIME is the most precious commodity I have now, and there are many things I want to use this time for before it runs out.

It is not new, it is the same China-made product that Madell has been
selling for many years (at least 15):

http://www.madelltech.com/m1-5.html

The manual is linked on that page, if you want to read more about it.
I have not seen a detailed review.

On AliExpress it's described as a "Yangzhong Caltek CA-4810A":

Hi Dan,
Can you contact me please.

I'm not sure how to contact you directly.

Circuit Specialists (Arizona) has been directly selling this out of their web store front for some time. I see that they are now down to a stock of only one.

For the real (poor translation) of the “Graphical Instrument for Transistor Feature” manual, go to:
https://www.circuitspecialists.com/content/511366/csi4810a_manual.pdf

Thanks for the referral back to the 09-07-19 postings, Dennis. It saved me some time looking for it.

I wonder if those small plugin test modules are compatible with the Tek 577?

Might be a cheap source of fixtures if so...

Assuming you are OK with sending yet more dollars to China. I'm not.

Hi Jim,

Without getting into international political relations I am curious to know your answer to this question:
If there was a scope in Tek's current catalog that you could afford which had features you needed to complete an invention you were making or troubleshooting would you buy it??

If you go back and read the entire thread I pointed to from last year there was some agreement that Tek must have been involved in the creation of this instrument because of several details we could see. In the end, if I remember correctly, its origin was a little more complicated than that. I believe we found evidence that it was made by a company formed with some former Chinese Tek employees and that explained the similarities.

Hi Jared,
I think the odds are 99% that they fit perfectly in Tek curve tracers for several reasons.
* Banana plugs are always spaced 0.75" apart.
* Tek curve tracers defined banana plugs as the interface for all of their transistor adapters,
* Banana plug spacing is a very old standard. Banana plugs were used extensively in many fields (the audio industry for instance) and they are on many instruments. Standard spacing was essential to interconnect the instruments.

Why not buy one, check its dimensions, and report back to us.

Hi, Dennis.

No, my intention was definitely not to get into the geopolitical realm.
That's why I made my post brief.

I suppose I would buy the Tek scope like you said, although I'd try to find out where it was made. I need to be more careful, as I just bought some MIDI cables on Amazon, and I didn't notice they were made in China until they arrived. I'm not sure what you're getting at, perhaps that Tek does some/all of its manufacturing in China these days? I guess that wouldn't be surprising.

So many reasons not to buy Chinese goods these days: poor quality, trade deficit, and the possibility that Covid-19 was bioengineered by the Chinese government to cause a pandemic and worldwide economic collapse all come to mind. Hopefully I won't start a firestorm on TekScopes.

That makes weighing scales and micrometers hard to use. In sum, what the Chinese lack is a quality aesthetic - an attention to detail, decent plastics, and CMOS technology.

BUT, in each case, they are improving. Every time I buy something from China, it seems a little better made than the last product I bought. It's a real boon for us electronics tinkerers and experimenters and repairers. I have a Chinese three-terminal component tester I use all the time. An LCR meter that's really nice, a really smooth X-Y table on my drill press. Oh, and let's not forget PC boards. 10 for $10 and a week's delivery time from Taiwan. I'm not sure I should even bother to keep my wire wrap stuff, nor all the chemicals I need to etch my own PC boards. It's a waste of space at this point. A couple years ago, in the context of getting young people interested in the hobby, someone here said it's a great time to get into electronics.

Anyway, sorry for continuing the off-topic thread, but it is at least partially relevant in that we all need to fix our gear at some point, and the resources available from "China, Inc." are pretty amazing.

That’s as likely as current US gov’t administration engineered it in an attempt to reduce Chinese foreign competition and it backfired.

Ridiculous?

No more so than your baseless conspiracy theory. There’s no evidence for either one, so let’s not engage in science-fiction-level speculation and pretend it has any basis in reality.

 

Hi Jim,
My question was meant see if you would buy a scope that appeared to be made in Beaverton. Your answer indicates you are firmly committed to not purchasing anything made in China even if it saves you money. I admire your commitment to your principles. As far as I know I don't own any Tek gear made in China since the 7K series and the TM5xx series was made in Beaverton in the '60s, '70s, and a few things in the early '80s. A few of the TM5xxx plugins were made in other countries. I have a few made in the Netherlands and a few were made in Israel (the serial number of these ones begins with the letter "I").

As far as I know everything designed by Tek engineers in Beaverton is being made in China to keep the manufacturing cost to a minimum.
Tektronix may not be happy about using the Chinese (I have no idea how they feel about it) but they have no choice since every other scope manufacturer is making their scopes in China. The only way to compete on price is by using Chinese assembly companies. Other reasons why Tek no longer does their own assembly: -
* There are many more companies making scopes today and the competition is fierce.
* The Chinese have captured the market for low cost price sensitive scopes:
* Scopes are not as essential today as they were 40 and 50 years ago meaning fewer scopes are being sold;
* Laboratory scopes (general purpose scopes that use plugins) have disappeared because their initial purchase price was high compared to portables.
* Laboratory scopes have been replaced by many different scopes each designed to perform a specific function. These specialized scopes are each less expensive than the general purpose Laboratory scope but fewer specialized scopes are needed.

Hi, Dennis.

No, my intention was definitely not to get into the geopolitical realm.
That's why I made my post brief.

I suppose I would buy the Tek scope like you said, although I'd try to find out where it was made. I need to be more careful, as I just bought some MIDI cables on Amazon, and I didn't notice they were made in China until they arrived. I'm not sure what you're getting at, perhaps that Tek does some/all of its manufacturing in China these days? I guess that wouldn't be surprising.

So many reasons not to buy Chinese goods these days: poor quality, trade deficit, and the possibility that Covid-19 was bioengineered by the Chinese government to cause a pandemic and worldwide economic collapse all come to mind. Hopefully I won't start a firestorm on TekScopes.

Jim

Hi Jim,

Without getting into international political relations I am curious to know your answer to this question:
If there was a scope in Tek's current catalog that you could afford which had features you needed to complete an invention you were making or troubleshooting would you buy it??

If you go back and read the entire thread I pointed to from last year there was some agreement that Tek must have been involved in the creation of this instrument because of several details we could see. In the end, if I remember correctly, its origin was a little more complicated than that. I believe we found evidence that it was made by a company formed with some former Chinese Tek employees and that explained the similarities.

Assuming you are OK with sending yet more dollars to China. I'm not.

Both curve tracers have different company names on them so I think neither company made it. The manufacturer is an OEM who will sell to any
company that buys them in quantity. This customer can then put their brand logo on it and add it to their line of test equipment.
I have similar observations. I have purchased three different pulse oximeters from "China, Inc." to test them out and have on hand just in case we get sick, and they are all Identical, except for the branding. They even came in the same exact box. Same as well for head lamps for walking the dog. Two or three different brands, but otherwise exactly the same. The headband straps suck, but the lights themselves are excellent, and bright.

It's an interesting business model.

TekScopes Group Description is:
"All about classic Tektronix test equipment, its use, repair, and collecting."

This would be a good time to remind everyone of what TekScopes is NOT about.
Inappropriate language and posts about the following topics were best stated by Stefan Trethan who said it better than I could:
"No politics, no religion, no sports, simple as that. This has been the golden rule for groups for a long time, because it works."
