Hi: Can I have a set of 4pcs white? tonycheung_hk@... I am from Hong Kong . They may ship by post ? Regard Tony Cheung 從我的iPhone傳送

Dan G, you are a search master. I have looked for Tektronix spectrum analyzer related application notes on the TekWiki site (and elsewhere) and only found a couple. Thanks to your skill, I have

Why not just make a new subject instead of hijacking? There are many different threads about the 2465B, which is the only thing common between the thread you're hijacking and your subject, which has

Hi Tony, I was able to read out U430 (base address 0x0000) from my 308 by tying pin 21 low. A quick look at the disassembler listing appears fine (interrupt jump table, initialization etc.) I've

I would check the flatcables first, maybe reseat them. Saludos, Leo

Where are you in the world? I'm in Spain. Saludos, Leo

Is it possible that the deflection plate connections have become disconnected or broken? I'm not sure where the horizontal plates connect on that particular scope, but if those are connected via the

Hijacking this thread under a new subject. I have a 2465B whose front panel is a bit flaky. Most of the time it's usable, but it occasionally has freakouts where the LEDs flash, display flashes,

While looking for the 212 battery end caps I also found what looks like a complete set of boards for a 2252. A few years back I needed crt and I picked up a damaged 2252 for next to nothing. I have

I have found in a box way in the back that contains 14 used battery end caps for a 212 and so forth. 6 black, 7 white and 1 grey. Any body want them? Pay for shipping.

Hey Roger, the DAC takes a reference current as input. It effectively multiplies that current, then diverts it to the two complementary outputs according to a programmed ratio. If the reference input

It may be the dreaded U800 horizontal chip failure. --John Gord

OMG how embarassing! :) Thanks!

All the pots on my scope are AB stackable pots with screws (though some of the screws are blocked by other components on the board, which means that I would have to remove the main board in order to

Team, I am not having a problem with my 308, just that I like to have backup code for the devices I own. I have only had a couple of EPROMs fail in the last 20 years but when you need code there is

The document ID is AX-3535. It is available on the TekWiki: http://w140.com/tekwiki/images/0/04/AX-3535.pdf dan

The Tek App Note AX-2535 is by M. Engelson and is titled "Crystal Device Measurements Using the Spectrum Analyzer". I am usually good about finding web stuff but had to admit defeat looking for this

Jeff- yes and yes. the pot in mine is a AB modular one could be made to be stacked etc. front and rear comes off....IIRC (it was 15 years ago ) I did remove the board to replace the section. I cannot

Renée, so you're saying that this is the pot equivalent of switch bounce? Now that you say it it seems almost obvious, and I was already trying to imagine a way that the pot could bounce like a

Bad news. I tried to adjust the DAC and realized that I could not do it. The maximum positive voltage that I can get is +1.18V while the max absolute value negative voltage is -1.019V. As I have said
