Re: J16 sensors

Hi Adrian,

I was interested to see your suggestion of substituting NiMH sub-C cells for the original NiCds in the J16. Are you using the original battery charger? According to the J16 manual the charger is simply a mains power cord, then transformer and voltage doubler rectifier with no charge control. The J16 battery pack is simply 4 NiCds in series and a fuse, so no charging control there.

I've replaced the NiCds in my J16 twice over 20 years and they need it again. I have always been a little disturbed about no active charging control apparently provided. Have your NiMH cells tolerated that charging method?

I've heard several people say that NiCd cells tolerate a larger float
current than NiMh. Since older equipment used NiCd, the float charge
current (typically the way the cells were charged, say a 15 hour
charge at 0.1 C), was too much since the NiMh cells expected a smarter
charger that turned that charge rate off and went to a (say) 0.05C
trickle rate.

I have a 214 I may eventually do something to in terms of a smarter
charger.

Re: J16 sensors

Ok, the answer is (for those that don't know) that the J16 has two power module options:

A mains power unit

A battery pack with a separate charger.

This is an either/or option where the chosen module is plugged in the rear and retained by four screws.  ( I replaced these with thumb screws)

The mains power module can be set for 120 or 240 operation with the aid of a soldering iron.

The battery pack contains six tabbed NiCd cells with a fuse and a 'standard' type concentric charging jack (2.5mm pin) on the rear.

I don't have an original charger but as been pointed out, it's pretty basic.

I have found that the cells are easily replaced with sub-C tabbed NiMH cells and an external NiMH charger with the correct connector can be found easily too - from the name on mine it looks to be aimed at the R/C model car racing market!

On the other hand, I brought in a 7704 with a 7CT1N and other plugins

7K series - Conceptual question - What's the 3rd most useful plugin

Fabio Trevisan
 

Hello folks,
Here comes a conceptual question... "designed to provoke an emotional response"...
I have this 7623A for a while already, for which I have the essential pair of plugins... A 7A26 and a 7B53A.
Everything is working mostly fine, and I don't quite "need" anything else... but looking at that empty slot there, sort of makes me sad.
Looking at the myriad of 7k plugins, I can't decide which one to look for next, so, for you 7K series long time users, I ask:
What's the 3rd 7K plugin that one can't miss?
Of course I know it's relative and know it all depends on one's most prevalent area of interest, but I`m curious to know if one or two in particular stands above the crowd.

For a starter, having owned for a while a 464+DM44 (which I gave to a friend as a gift) I miss somewhat the Time and 1/Time functionality. Is there a plugin that fills that gap?

I look forward your opinions,

Rgrds,
Fabio

I'd look for another 7A26 to get four channels. That's thing one.

OK, then A 7D14 or a 7D15 will do time and period.

A 7D12 with the right plugin (M2, I think) will do a readout of a
waveform at a particular point (you need the B timegate to trigger the
plugin).

I'm assuming that you have on screen readouts, though.

AFAIK, the counter plugins need to be put into a horizontal slot to show the frequency of the signal into the vertical plugin.

How about a 7A13?

Or a 7CT1N for curve tracing? The 7B53A has the right (amplifier) mode available.

That's correct if you want the trigger output from the vertical
plugins to be internally routed to the counter. You can likely feed
the counter from the vertical signal output, but under chop/alt you
won't get good stuff.

Still might be useful.

Low frequency differential inputs

also consider a 7A22.

Yep, unfortunately, they seem to be rather expensive.


If you really wanted to go a bit farther, then perhaps a 7D20.

Sorry, I didn't know that.. My perspective was from where one of the bigwigs here asked people not to contribute to off topic posts. He cited bandwidth and all, and made sense.

I understand now - and that there may have been foul play involved I guess ?

I hereby retract my previous statement. If someone in power would like to remove BOTH of my posts in this thread I understand completely.

Re: 7K series - Conceptual question - What's the 3rd most useful plugin

 

Hi Fabio,

Raymond is partially correct.

A 7D14 does not measure period. It is strictly a high frequency (512MHz) counter.
The 7D15 is a universal counter / timer. As such it is far more flexible. It will automatically monitor the trigger signal if it is in a horizontal slot but it CAN also be used in a vertical or slot by connecting the signal being measured by the vertical plugin to the A or B input of the 7D15.

Your choice would depend on what you want to do. Several people have recommended the 7A13. I can add one more important who has told me on several occasions that he thinks the 7A13 is the most useful plugin. That would be the design engineer of the 7A16A, 7A18, 7A24, 7A25 (not produced), and 7A26 plugins, and the 7854 scope.

I like the 7A13 also, and, like you, I was annoyed for many years with the empty slot in my 7704A. I solved the empty slot a long time ago. Unfortunately, I didn't know when to stop.

If you purchase a 7A13 make sure to get one of the digital ones. The plastic used to make the gears in the mechanical 7A13 expand over time and crack off their axle or jam up. This can't be fixed.
