I sold something on Ebay but my money was put on hold for 2 weeks. My item is already delivered. Here is the explanation: Me: No one has ever given me less than 100% FB in over 20 years. 12:37:53 UTC

Exact, I mistyped the correct funcion...I have a similar problem on my 53131a but it looks like to be a relay. Ch1 does not work, but if I change to ch2 and back to ch1 it works flawlessly Enviado do

I’ve selected input 1 and 2 via the Frequency & Ratio button and channel 1 or 2 light blinks. It’s in Run if that’s Auto? Drew

No question is stupid, but...have you selected input 1 or input 2? Is it in auto or single? Enviado do meu Tele-Movel Em ter, 15 de fev de 2022 22:28, Andrew Curlik <kb2lmn@...> escreveu:

Hello all, this may be a stupid question but I just purchased a 53131a with 3GHz option and can’t get a frequency to show up on input 1 or 2. Being new to this I’m not sure if I have a setting

Hi all, and a 401 point sweep with minimal dwell time of 1ms takes around 22-23s to complete. Br Marcus

Hi, The E44xx series generators do not have continuous sweep. So, as you mentioned, there are sweep from a list or by defined step, but only for 401 points maximum. Yves De :

Hello, I am considering the purchase of an RF generator for R&D and RF alignment purposes.? Looking at the Agilent 44xx series, it looks like the sweep functions are Step and List Sweeps.? I read

Listen to Dave Wise. His info on the TL431 fix for the Krypton doped neon lamp works very well. It’s in the group photo section, page 4 I think. Add the diode he mentions in the text for better

I apologize, it was just a suggestion. wrote:

I had a very similar rig and had to replace the fuses with slo-blo types. That feels like mostly a band-aid, but it worked. Steve Hendrix

This is a well-known problem. The glow-tube voltage reference (V1) may not read high on a voltmeter, but it is “lazy” starting up, and during that time the power supply output overshoots. If it

There are a number of neon lamps in the power supply circuits that act as simple voltage references. As they age, the 'strike' voltage increases and eventually gets high enough that circuitry down the

Maybe a dumb question, but is this, by chance, a case of using a fast-blow fuse where a slow-blow fuse is specified? Thanks, Barry - N4BUQ

I was recently given an HP141T / 8552B / 8554B spectrum analyzer by a retired electronics engineer. It looks ine xcellent condition and I believe he would have looked after it.? He warned me that it

Walter - I do understand the issues you describe and I apologize for perhaps being overly critical. Additionally, most of my criticism is from some time ago. We ALL have hot button issues, this is one

I don'r know at all python anyway i tried but got this error: File "dump_fw.py", line 9 def dump(mem_addr, length, *, gpib_addr=7, device_addr=0): ^ SyntaxError: invalid syntax hopefully we can fix so

Oh, and if you are driving an inductive load like a relay coil, motor, or I suppose an incandescent bulb or a speaker, don't forget the flyback diode to protect the driving transistor.? A fast
