In my opinion, the only HPAK spectrum/signal analyser that can be expected to work (very) well with the noise figure option and a 5dB ENR HP 346A noise source is the classic E444xA from about 20 years

For comparison, here's my Q-measurement of a 6.2?H air coil? at?? 8.28MHz Measured with the HP4342A?? Q=221???? VNWA shunt-through measurement see graph.

I checked all power rails again, no problem. The I worked backwards from the deflection plate drivers (A13), injected some signal, and got deflection. Worked back to Q23/S24 on A8, and get deflection.

Hi all, I have a HP 1725A 'scope here, with no horizontal deflection. Vertikal deflection is working fine, I get a vertical line if I feed it with a sinus, or two dots when i feed it a square wave.

It is the 5032, http://www.qdkingst.com/en/products , I was typing from memory and the manufacturer name probably stuck because it is the software I see the most. It has a nice dev kit and I have

Charles, Many thanks for this graph. It is very interesting as it also mentions the good old (and still very useful) HP8970B NFA. Googling the doc number in your message comes up with the doc:

Hello Charles, Can you please share the 5989-8056EN document you have? I cannot find it. I would like to read it since I was also looking for the Option 219 card to add it to my ESA. 73, Razvan

Hi Bruce, Thanks for the valuable additional information. I'm arranging 8510C with display units with LCD and the latest firmware 8.XX so I wanted to know if my 8341B will work. But I will try then

Dear Charles, thanks for this valuable feedback. I was not aware of this at all, and yes I agree this makes the option almost useless. I was tempted because of the wide frequency range. Hhwever I now

Hi Olaf, before you pursue this option further you might like to read some of the manufacturer's documentation on that option. An early version of 5989-8056EN included the below plot which includes

I'll just post some shots to answer the requests earlier up the thread. This first one is the set-up I'm using. I have had to resort to some longish leads to connect the items together, but this is

Dear All, I like to extend my Analyzer with the noise measurement option. Does somebody want to sell a E4401-60123 Board + Cables ? If yes please drop me a reply or send a pm. thanks for reading and

Yves, Some good news, the spectrum analyzer is now passing self cal and conf test with a 300MHz marker at -20dBm at both Log and Lin setting. I was still poking around a bit, found some more (maybe

I use an 8340A with SW rev 23 May 1985 with an 8510C with SW rev 7.16 - hope this data is helpful,? I have also used other 8340Bs with various SW revisions and never had any compatibility problems.
