Perhaps a picture would be useful too. Daun Daun E. Yeagley II, N8ASB

Ham Radio magazine (Dec. '77) had an article on building a "bolo-meter" type rf power meter ...Used small light bulbs in the sensor . I found a few pilot lights from old cb's that had the right

Hello, Addressing another device using interactive IO doesn't seem to release the 436. What I did find out though was that viRead - wich is what interactive IO actually does - gets 14 characters

I guess a part number for the attenuator in question would help. Everyone does not have 86603A manuals to check the part number. The o-ring failures are quite common. The attenuators with o-rings are

Chuck and others, No doubt you are right about the small light bulb been used: Here is my memory from EE school: In ancient times, the 1960’s (if I remember right) a bolometer system was

I had asked if anyone was familiar with this type of atten. NOT the 8495 style, but a long stick. I guess no one reads. NO O rings. JeffIn a message dated 11/20/2018 7:02:42 PM Eastern Standard Time,

NOT O Rings. Different design than the small flat guys.

Try addressing another device?? (Even one that doesn’t exist...) Dave B (G0WBX) ------------------------------------------------------------------------ *Re: Readings from 436A power meter using

Hi Ed, The output pulse is inhibited while the switch is rotating by?the pulse from?contact 4F on S1 (attenuator level) this feeds an RC network R18/C4 and Q2 on A7. If you turn the switch too fast

Hello, Indeed a point. Not having a second 436 around, I will try this one and see where it gets me for now, but if anyone would send me a 436 - I’d be happy to test :-) Regards, Staffan

It’s not impossible that you have a stuck gate somewhere, and the operation you observe is not normal for the instrument. It’d be worth checking that against another 436A. Cheers, Kuba

I'm fixing up a magnetic step attenuator salvaged from an 8555A SA plug-in, to use in my TG project. I have some of these nice old attenuators, and the special rotary wafer switches that encode the

Beginning at around 47:50, in the following video, https://www.youtube.com/watch?v=py06VNvykTk&t=2939s he discusses HP tc and diode power sensors, and shows a strip down of a diode one. There is some

I have never failed to locate a needed o-ring at Mcmaster Carr.? Google their catalog. Sent from my T-Mobile 4G LTE Device

Here is a video on repairing one of these attenuators: https://www.youtube.com/watch?v=eChxU90OgGk The O-Rings are 2mm od x 1 mm id x 0.5mm thick. Theses are used in watch

Hey Jeff. Have you measured one to check the size? I have several sources that might be able to supply them - 73, Bo L.

Sounds like the universal problem of decaying O-rings Jeff.? They are easier to replace than source. Dan

Hi Jeff, I would be very grateful to receive it, whether it is for a 606A or 606B. Beggers can't be choosers! I'll await your advice. (Fingers crossed!). Hi Kim, It may also be possible for me to

Hi All! Dont ask why, but I am resurrecting several HP 8660D generators with the HP86603A plugin. The attenuators are "sticky", get stuck in a certain position. If you have experience with this exact

Hi Ken If you google "HP 1703a" the first hit is an operating and service manual. It's actually a 35MHz scope. The HP memory project also has a nice article on the 1700 series.
