Mouser also shoes the wrong picture. I use these: Lumberg Series 03 - Circular connectors with threaded joint M16 acc. to IEC 61076-2-106,

Hi re HPIB I am not a computer programmer but I either use HP basic 4.1 with a HP computer that has a HPIB port or national instruments lab view on windows xp and the hardware is either a

Hello, Thanks for the suggestion. I have tried this, but it doesn't seem to work. Any recommendations to how I should configure Interactive IO? I will use Visual Basic in Excel for later programming

In my connector search above, I didn't pay any attention to how the connector mounts onto the device.? For a new homebrew design, it probably doesn't matter.? But, if you are specifically trying to

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

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

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.

Yeah, that would be bad, essentially counterfeit sensors made from shells of fried ones.? And they would sort of work, just nowhere near spec.

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

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

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

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

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

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

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

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

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

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

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 -
