HP specifically states on their spec sheet for the 3586 that the 75 ohm port mates with the WECO 358A plug. Greg

In a typical HP YTO loop config, one end of the main coil is connected to -40V, the other is connected to the emitter of the main coil driver. The current through the main coil is controlled by the

Almost all of the connectors that you will find that are made by Trompeter are not compatible with the WECO 358. Be careful, the shield fits, but the center pin won't engage. They were made for 75

You might also consider picking up one or two WECO to BNC adapters for the unit. It would save the effort of having to disassemble it and change over to BNC connectors. If you use the search terms

I have a Ballantine 323 AC voltmeter and a Boonton 91H RF "millivoltmeter". The Ballantine is solid-state and has a usable range to 20 MHz, the Boonton is vacuum-tube and has a usable range to 1200

Before I resort to that famous auction site I wanted to inquire on this list to see if anyone might have parted out a 436A power meter and have a spare front panel in good condition available. I

Hi Lamont According to the HP 3586 user manual the B variant already has a BNC input that is switchable between 50 and 75 Ohms. The A and B variants were teleco "specials" the C variant was the

Lamont, Download the manual, look at the matching network. You will see how easily you can make it selectable for 50 or 75 or whatever tweaks your tuner. There may be several illustrations for

The big limitation in using probe type RF voltmeters, is the probe. It becomes very difficult to establish a good low impedance ground above perhaps 700 MHz, making measurements questionable. This

I don't see any other fole for the 3586! Lamont

Under FILES> 3586> 419MB---- file empty. Anyone known why I can't see the files? Thank, Lamont.

I waiting to get it, I 'm pretty excited, but also concerned it will need repair. In the listing I note is the display has error code of CE-1. The manual says, "Operator error, Attempt made to

You need to investigate, and measure Allen Variance, a better indication of the quality of an oscillator. What you will most likely find is the GPS disciplined oscillator, though very good in terms

I liked the story about the man with 3 watches. This is what measurement is all about, making a conclusion of the data that you have. The measurements give you an indication of the precision you have

"Not very expensive" as in "compared to buying a particle accelerator" ? ;)

Hi, I was able to remove theYTO from the instrument and test it with the aid of a spectrum analyzer and a few power supplies. Mine needs +20V, -10V, and

We need extreme freq stability for our master freq reference for a particle accelerator that is 770 meters long. The original 46 year old oscillator was first a HP107BR special that was at 6.289xxxx

Thanks to all that responded. I am playing with a receiver for Navtex. Problem there is that the nearest station only transmits for 10 minutes (max) every four hours so that makes tuning the receiver

It's similar to the HP 3400A and the Ballantine 323. The HP 3403C is a true thermal RMS meter, with 100MHz bandwidth.
