A question or so: 1) is the equipment supposed to run at 230 VAC?? Are you in a region where you could get 240?? Is it specified for that? 2) any idea if it's a supply triggering this, or a general

Digging a bit more I find that the PSU will start successfully at 220V AC and at 225V AC. But at 230V AC and above it throws and over-voltage error. Not quite sure where to take it now... Tony

If I'm not mistaken, the designer of the 8671/8672 is (or at least was) on this mailing list. Perhaps he'll chime in. -Dave

I have not measured it to be frank. But both of the above tests were with the variac set to 230V - either powering on the instrument and turning it up gradually, or otherwise setting the variac to

Hi Tony What is your actual mains voltage? G Edmonds

Hi, I'm hoping somebody can advise me how to approach a power-on issue with my HP 8662A signal generator. It came with a faulty power supply and I went through a detailed fault finding process and

Many years ago I remade/copied the original Agilent card. It works fine. I think the Chinese did the same thing industrially.

Are the video amplifiers 50 or 75 ohm?

Hi Dave, There is some info in these posts: /g/HP-Agilent-Keysight-equipment/message/111396 /g/HP-Agilent-Keysight-equipment/message/103664 Seems as the only

Generally use the distribution amplifier outputs it’s the best way to do it and also make sure to terminate the unused outputs ! As far as the 8671B concerns, turn on the unit and let it warm up,

I bought one a while back for my 53132A. I haven't done much testing of it, but it seems to work just fine. Keith

Sounds like one or more of the fingers in the range switch have let go of their supporting disc. If that's the case, they're probably wandering around in the bottom of the cabinet so carefully

Hi, I recently cheaply (< $700) acquired working (they power on) set from a deceased engineer's estate sale in the US: * HP 8566B 100 Hz - 22 GHz spectrum analyzer (two sections) * HP 8671B CW

Hello All, Can someone point me in the right direction? The HP 8640 has output on all ranges. The frequency counter is accurate on the 4 to 8 MHZ range ONLY. ALL other ranges are way off. Any ideas?

I haven’t bought any of them so I cant attest to how well they work but $40 aint all that much money to give it a try

Some have reported great success using Tri-flow as a lubricant on hardened grease that TenTec used on their vfos.? Reports have it that TenTec used whatever tractor grease the farm store had on the

Hello All, I am thinking about getting a 3 GHz prescaler board for the HP 53181A from China.? They are only about $40US.? How well do they work? Tom N3AJA

wrote: Thank you. Do you know if it’s possible to extend the frequency range to 46 GHz? Not that I can think of a use between 40 & 47 GHz, nut if an upgrade is possible, I might be interested. Dave

Yes the 5352 was 40GHz however HP used the back panel for different models not just the 52 , the 5361B pulse counter for example had options for 26 and 40GHz and the 5352 had options for 46GHz Sent:
