Re: HP 8595E Restore and Tracking Generator Questions
Ah, the too much current for the relay coils issue.? About 20 years ago I had to design a circuit to put out a pulse of current to kick-start a relay.? The hold current necessary to keep the relay

Re: Agilent E4416A series power meter
There were a couple of Agilent service notes relating to problems in the E4418B meter through a wide range of serial numbers where the units would not power up or at least give a display. I¡¯ll see

Re: Waveguide items OT
Sorry HP/Agilent group. I clicked reply thinking it was private. I am trying to keep this away from this site but wanted people to have a chance at some nice items. I am in Deep River, Ontario,
Re: Waveguide items OT
My HP8757D is the problem. The two chassis are big and heavy and I don't want to ship them. I have a couple of interested parties. If not for this system I would be prepared to sell the waveguide in
Re: HP 8595E Restore and Tracking Generator Questions
Chad, For the money you will spend on getting together the components to add a tracking generator to your SA, you might want to consider any of the tiny VNA variations available. I have the 9593E

Re: HP-8753E Option Key Installation Failure
Hi Jeff: I am afraid there is no schematic. That is the biggest part of this troubleshooting endeavor. I am relying on the EEPROM Data sheet to draw conclusions. Then data sheet tells one simply how

Re: Agilent E4416A series power meter
The E4416A is very similar to the E4418/19 series.? The power circuit is the same.? The measurement boards are different.? The schematics for the E4418B are in this package

Re: Agilent E4416A series power meter
If I am correct in a quick interpretation in the service manual the power switching comes from MOSFETs located on the processor board which distribute the power to the remainder of the instrument.

Re: Agilent E4416A series power meter
Agree w/Greg on the poor service manual. No schematics! You need to investigate the "soft start" circuit. There should be a standby supply voltage present for that to work. This repair video talks
