Well I pulled the cover off and unsoldered on lead from the switch.? Sure enough it was open.? I hit it with some deoxit from the top where there was a grove going in and worked it a bit and it

My apologies. I May have misunderstood your issue. I was thinking about the internal battery option for use of the instrument without any mains power applied. The 2.9V you measured most likely applies

OK, we have replaced the diode in our 8471A, and learned a few things along the way. In my preceding descriptions, I had Anode and Cathode reversed (for the standard Negative Output model). It is

I have a E4418B power meter that uses the E9287A battery. It is a 12V battery. Does your meter use the same?? Part number and normal voltage should be printed on a label on it.?? If yours is the

I get a hint the op may not be very familiar with digital logic, so I need to mention the idea of inverted logic values where true is low or ground. The data sheet or schematic shows this as a bubble

The scope came with A.02.08 firmware which I believe is the latest. ?Updated my old scope with this firmware and it works fine. ?If I get time tomorrow I’ll upload the firmware images to the files

I have agilent E4416A series power meter. the voltages are ok 12v,-12v, 5v and the battery measures 2.9v the stand by light is on but when I press the power button nothing happens you can help me and

Atilio, You may also want to look into Pete Millett's software - http://www.pmillett.com/hp_8903_software.htm. No affiliation, but wanted to save you the time to search. You'll also need a HPIB/GPIB

This analyzer has not 4400 hours but 6278 and does have the original display tube. Price 1550 Euro Payment through paypal. best regards Peter

PIC would do it if the PIC had A/D converters. Looks as if the PC utility is the way to go.? No sense duplicating work unless you need something different. Good luck with how it works. Harvey

For sale is one of Hp's top models. It goes from 9khz to 26.5Ghz. It is synthezised controlled analyzer and measuring / counting frequency down to 1 Hz resolution. It is an A model that has a

Thank you so much Harvey, unfortunately I don't know the Arduino, I only have experience with the PIC (eg 16F628A). But i n my research on the net I fortunately found a utility for PC which, through

Hi Harvey: Yes, I will start looking those. I am sure there is some tutorials on YouTube that could be watched too. It is clear that it cannot read based on how the pins are set when attempting to do

If the outputs are analog, then an arduino doing the A/D conversion (pen lift active means ignore inputs).? Output those values on a serial data line to an off the shelf serial to USB converter and

Good day everyone, I recently bought an HP8903B audio analyzer that has output terminals (X-Plot, Y-Plot, Pen Lift and GND) to connect an X-Y plotter that I don't have available. I would like to ask

Hello, Has anyone found a replacement (or know the Keysight part number) for the spring metal clip that provides a ground to the front panel of the 3458A? It is a small <1 inch clip, bent in the

Hi, Has anyone managed to get a copy of the HP70875A on a card? Hope to hear, thanks, Bas.

OK, then this gives me an idea of what you might be familiar with. I'd suggest looking for some 6800 or 6502 data sheets that include read and write timing diagrams.? Any tutorials that include basic

Hi Harvey: Thanks this is helpful information! There is, what I am pretty sure is RAM located on the same board. Based on my brief reading of the service manual while attempting to source schematics,
