Hi, call rick at amtronix to get the attenuator, label and call data for $125

Hi there, I have an 8921A that needs a hgh power attenuator. they seem to be out of production. I live in Perth Australia and wondered if you can advise a supplier for the stripline type 50 ohm

Hi Robert Thanks for that. Nigel Vk2NB [email protected]> wrote:

They ARE SMC. They go to J55 and J56 the underside of the motherboard. On a non option 50 unit there is a simple jumper W13 This is just a V shaped bit of semi rigid coax, the same as type as used for

Hi Yuri Thanks for the reply The ports i am talking about are the iq rf in and cw rf out, emailing Rick from Amtronix he believes they are a smc connector. The 8921a will not out a signal to the n

Those are smc connectors. I have a boat load of smc jumpers if would pay the postage, rick

Re: [HP8920/8935 Family] HP8921a Cable Hello, Probably you are talking about connectord for cellular adapters (part of Option 50 if memory serves me correctly). Not sure, but probably there is pair of

Hi Casey, I can certainly endorse your praise for? Amtronix and Rick. I n 2012 I acquired an 8935 E6380A from a supplier in California.? I found Amtronix on the Web, called Rick and ordered a return

Hi to the group I have a hp8921a test set, and on the rear of it near the ac mains power connector there are some connectors that have a patch lead between them, the best way to describe them is like

RF-Microwave sells the Anaren H100NA20X4. It's the one I used. There is a picture of it below. You have to grind the flange down about 1mm each side to fit good. It's $38 as opposed to $350 from "them

since this is an 8920A may be more of a challenge since you need the calibrate routine and data ( usually fixed for the most part anyway) on an Epson type card. Probably cheaper to just replace what

Yes it would be, I am not to sure how to do so. I would need to re-calibrate data ?

This would be the perfect time to upgrade the power capability if you desire to do so....

Dear Jon, ??? If you need that part, let me know. We have many here. Rick

Thanks everyone, After further investigation, it appears to be the 4db attenuator on the A4 Assembly. It looks like some signal was passing through (extremely low), only enough to read frequency etc.

The input resistance on the RF I/O? should be? very very? close to 50 ohms .? Usually? well within 5% and my upper limit is 10% ...should be? easily within 45 to 55 ohms ( make sure you factor

Thanks for the suggestions, I will check it out later today and let you know what I find. Just for reference, this is a 10watt version.

I recommend you measure the resistance from center conductor to shield of the R FIO connector. You should measure around 50 to 60 alms. Could be that high power and put a tenuator is open? Rick

Shortly after I got mine (about 15 years ago) - I discovered the same symptoms. I would first look at the attenuator on the A4 Assembly. My original one had the solder tab burned in 2. I guess enough

Hello, I am experiencing an issue when a device is connected in to the RF input. RF ANALYSER? screen RF POWER - The test set always displays a reading under 0.1 watts. even though a signal in is 5
