Hi All, Has anyone seen and fixed this error before I pull the case? Thanks Chris

Re: HP8510C "system bus address error", but then it works
Also check RF Switch address. It must be 31 if you havent switch. Wrong address cause "System bus error" message. [System][F2=HP-IB Addresses][F6=RF Switch]=31

Agilent/Keysight AWG 33250A /33220A CAL
hello everyone Bonjour a tous... This fine 80 MhZ AWG (circa 2016) needs a full calibration similar to the 33220A 20 MhZ. Do either of these generators, use a back up battery or NV ram that can lose

Re: Agilent E8357A Network Analyzer Phase Lock Lost Error
And your reported 10 . 000447 MHz? results in error still.... Yes place your counter into ratio mode to properly address counter faults...

Re: Agilent E8357A Network Analyzer Phase Lock Lost Error
I suggest you place your counter into the RATIO MODE.? What I am addressing is rule out a faulty divide by 2 counter.? ?Since this a significantly robust phase lock synthesizer system, makes sense

Re: Agilent E8357A Network Analyzer Phase Lock Lost Error
That is pretty bad. An ovenized crystal oscillator should be able to do at least 10^-7. ¨C Mike Mike B. Feher, N4FS 89 Arnold Blvd. Howell NJ 07731 908-902-3831 Sent: Sunday, May 25, 2025 1:04 PM To:

Re: Checking an 8402B Calibrator
It might be simpler to put a 100M ohm resistor in series with the high input on the 34401A in the High Z mode. Your 17.8V reading will now be 8.9V well inside the 10V limit for the 10V, 100M ohm

?Marko, The system may have been set up to use two sources and it¡¯s looking for the second source. Try: Instrument State <Recall><More><Factory Preset> Regards, Steve

HP8561E Jittery Display
Hi, I've some HP specans just obtained as BER items from a local space communication site. The first one I'm looking at is an HP8561E, it powers on OK and the display is bright but the text is jittery

HP8510C "system bus address error", but then it works
Got my hands on a 50GHz 8510C with test set and source, everything mounted in a mobile rack with a pullout table. When I switch it on, it says "caution: system bus address error", but them it proceeds

*Actually measuring again with a counter I come up with 10.000447* *Not to say my equipment is perfectly accurate.*

Re: HP 8902A Measuring Receiver
Hey there Raymond, I've done a little futzing with the power supply and the input amp on my 8902, so I'm happy to try and help where I can. I think you might get more traction on the group if you

Are you saying 4.999756 is in error?

I have been downloading files with "wget" for many years, but never used the "-c" option (I guess as long as one just downloads "regular" size files, it doesn't matter that much). It worked like a

Why is the 5 MHz in error, while the 10 MHz is correct?

Re: Checking an 8402B Calibrator
Tony, If you have or can borrow one, the Fluke 8840A does High-Z up to 20Vdc. --John Gord
By John Gord · #152037 ·
Re: Checking an 8402B Calibrator
Thanks, Jim & Charles - Appreciate it. Where I find myself is that the 8402B manual says to look at a voltage that is around 17.8 Vdc above the -30V rail (Section 5-7 in the manual) - This pushes my

Re: Checking an 8402B Calibrator
Hi, the 34401A can do >10 G¦¸ input R but only on the 10V and below ranges: Blue Button (Menu) On/Off (Down arrow) (Right arrow) Enter See pages 27 and 53 of the manual (well the year 2000 version

Re: Checking an 8402B Calibrator
Try using the 34401A in hi-Z (high impedance) mode, Tony. I had to do that once about 10 or 15 years ago when measuring voltage in a low current circuit. Got weird results until I switched it to hi-Z

Checking an 8402B Calibrator
Hey All, I'm looking at an 8402B calibrator, and the manual says that the measurements need to be done with a floating DMM that has a greater than 100Mohm input impedance. The manual says to use an HP
