Hello all, Bumping for Ed's response and to give further detail of my own search. I did a bit more searching and found a pdf from a polish? ftp. Google

I have had the T962 (with the third party EST mod from day one) and have found it works well. I strongly recommend fitting that mod kit. I also tend to only use approx 60-70% of the drawer area when

Hi Adam Thank you for the information about the memory card required as being a 128K memory card I am not a software guy or very pc literate so the listings below mean nothing to me, but I have

Hi, today I have dismantled the YO loop assembly, which contains the YTO as well as severak directional couplers etc., see here, this is my

I made a toaster oven reflow oven, and it works very well. I have made about 70 runs, building 50 SMT boards, sometimes 5 at a time, and all came out soldered correctly. The temperature delta across

Ok, I was not familiar with that generator. As it is 10 MHz max and specializes in lower frequency operation and a variety of Z outputs as well as balanced and unbalanced... Not as straight forward as

Thanks Paul, I'm located in the Panhandle of Florida, in Shalimar which is just north of Destin on the Bay. One mistake in my previous post is that the total size of the files on the

Hello-- Not for an HP nor a Tektronix product, this manual consists of a commercially-sold and bound copy of the manual for Texscan's VS-90B sweep generator (covering 5 MHz to 2.35 GHz in three

Yes, I have one, it works okay after a third-party firmware mod and some minor hardware modifications (notably the firmware mod supports a temperature reference; the stock firmware just assumes iirc

Anyone have any experience or have colleagues who have experience using the Chinese-made reflow soldering ovens such as those being sold on the evil auction place? The one I've looked at is item

Andrew, Give it a few days for other people to check in before you DO anything. There are some VERY knowledgeable people on this list who know far more than I do. Spend your spare time studying

Hi re fixing 180 from memory Before removing the transistors a simple test Have you tested all the power supply rails on the pcb for the main frame for this test I would remove the plugging just

Hi Alan Thank you for that suggestion. That seems much more sensible than my plan. Perhaps the external attenuator could be made from the 0.25% resistors from the old unit. It is an 654A which only

The resistors in the deflection amplifier output stages (in this case the horizontal deflection amplifier) have an annoying tendency to drift much higher in value and eventually fail open. This is

Oh, I assume you are addressing an 8654A?

Hi Chris, If it were my generator, I would look at the effort involved with your approach as opposed to fixing the power output at a constant level. Will assume the ALC or power leveling is

I have a fluke digital multimeter, a weller soldering station, and not much else. I'm slowly building up what I can when I have a specific need or find a good deal. I bought a set of probes for it

Calvin, For your VNA measurement (12-15 GHz), and considering the budget, I would get a sliding load and a set of HP shorts/opens on ebay. I say "HP" because the calibration constants for those are
