Re: A homemade diode power sensor for HP meters
The 12-pin circular connector used on the power sensors is an Amphenol.? The old part number was 91-T-3638. Now, it's part of their "C 091 A/B/D" series circular connectors.? Several variations are

Re: Measuring Phase with Agilent E5062A ENA
Dear Gedas, There is a way round this you might find useful- reference line extension function; I used this on an 8753B to take out the delay in a long optical delay line. Essentially, you sweep

Re: Measuring Phase with Agilent E5062A ENA
Have you tried displaying your results on a Smith chart? Check out Dr Joel Dunsmore’s book, “Microwave Component Measurements” for more than you ever wanted to know on the subject.

Re: A homemade diode power sensor for HP meters
Yeah, that would be bad, essentially counterfeit sensors made from shells of fried ones.? And they would sort of work, just nowhere near spec.

Re: Measuring Phase with Agilent E5062A ENA
Thanks for that. It does in fact say phase is measured +/- 180 degrees. Earlier I ran a quick test using the expanded phase format and I think it is in fact exactly what I want. Below is the same

Re: WANTED: HP 606B Sig Gen RF Output Attenuator Module A10
Hi Graeme!! Can you use a 606B attenuator assy, that needs a resistor or two replaced?? I have an attenuator that was replaced in a 606B, because it got across mains voltage and took out two

Re: WANTED: HP 606B Sig Gen RF Output Attenuator Module A10
Suggestions: 1. Find an NOS A10 module (eBay or other). Not easy, probably expensive. 2. Buy another 606B being sold 'for parts' and scavenge A10 (hopefully it will be a good one). Shipping will be a

Re: Measuring Phase with Agilent E5062A ENA
Not off hand.? I'll have to check with some friends and see if there's anything in app notes or other reading.? Remember what I just said..I've been retired too long!? :-) The plane just went down

Re: Measuring Phase with Agilent E5062A ENA
Well the airfield across the road is always ready for you <g>. Do you know of any good HP or other source of reading material that may describe POS PHASE & EXPANDED PHASE etc ? Gedas, W8BYA Gallery

Re: Measuring Phase with Agilent E5062A ENA
Indeed! Yeah, unfortunately, the ENA won't do it.? Not sure if some of the new ones will or not..... I've been retired too long! Still have to get back up your way... maybe in the spring! Daun

Re: Measuring Phase with Agilent E5062A ENA
Hi Daun....long time no chat. Yup understand 100% but was hoping that the ENA had a function to do that for me. There are some "VNA's" that will do that for you. I guess this one will not

Re: Measuring Phase with Agilent E5062A ENA
Gedas, what you are seeing is "phase wrap".? The detectors in the VNA's can't resolve more than 360 degrees... 370 degrees looks the same as 10 degrees! The only way you can do it is to count how

Measuring Phase with Agilent E5062A ENA
Can someone point me to some reading material to help me understand how to measure phase on my ENA? I have the operators manual but it is not at all helpful. In short I chose a simple ~19" length

Re: Readings from 436A power meter using 82357B USB-GPIB?
Hi Staffan Yes, you need to meter to be in addressable mode (or as you say, "normal"). If you use the interactive IO, you would use the "Send and Read".. Type the command to fetch the reading in the

WANTED: HP 606B Sig Gen RF Output Attenuator Module A10
Needed to repair a 606B. My preferred repair solution is to replace the faulty A10 attenuator module with a serviceable module. The existing module has three coax cables hard-wired internally to it -

Re: Issue with homemade diode power sensor for HP meters
Hi Tobias!? Great experiment. Now add C2 & C3, c6,c7,c5 & c8.? These caps are part of the AC circuit and are used for balance in the autozero (C2 & C3). HP did not put in parts they did not need! I

Re: A homemade diode power sensor for HP meters
The worrying thing is the Chinese counterfeiters will probably do just that. eBay seller yixunhk springs to mind - someone called them the HP rebirthing centre. I can see them "rebirthing" power

Re: A homemade diode power sensor for HP meters
Hi Tobias, I looked at the OP again, and realized that you already knew about the "mount" resistor - I didn't notice that the first time. I grabbed that 8484A manual pdf that Orin linked - thanks

Readings from 436A power meter using 82357B USB-GPIB?
Hello, Just got hold of an old HP436A power meter and would like to do some automated measurements. Controlling the instrument is simple using the 82357B USB-GPIB module (I can set range etc), but
