I guess by working from a single sheet from an old manual and never noticing that it was there. Thanks for waking me up !

It's in the service manual, Test #55. How did you enter Option 006 (Test #56) without the the manual? Vladan

Hi ? I am looking for some guidance. ? I have an 8752C … it has option 003 3GHz ? I got the keyword to add 006 6GHz … I wasn’t sure if it also required additional hardware. I installed 006

Hi Dave, It’s the flange/ear for use without handles. I don’t have handles or I’d be set as I have a flange/ear that would work with a handle. Steve WB0DBS

Which part is this again? It's 2U, that I know, but is it the rackmount flange for use with a handle, or without? And it's the ear, not the handle, right? -Dave -- Dave McGuire, AK4HZ New Kensington,

Found the part number (5062-3974) but not the flange. There are two offerings on eBay but both are for pairs, and way over budget.

I have two 8713Bs for sale $1200 each. They have all the modifications available with EPROM change. Attached pics are screen shots with one unit on transmission with thruline and one unit on

The good A11A5 Sampler: Top trace is the emitter of Q7 and mixing to the correct frequency is obvious. The lower trace is the IF out on J5 and was used to sync the 'scope. These are the same signal

Alwyn, Your results match what Ed found - see attached email. I believe the unit Ernst has is faulty. The original query was for results of tests done at (Fc) 500MHz but repeated at other frequencies

Dear All, Following the earlier thread on a spurious at -10.7 MHz to the wanted signal, I took a look at the Cal. signal on my 8568. I have spurii at -9.98 MHz and -14.98 MHz. Both quite low level,

Thanks Dave, I’ll give that a shot! Steve WB0DBS

The one with the .IMD extension is an ImageDisk image, which explains why Teledisk won't read it. ;) ImageDisk is gettable and easy to get running, if you already have a Teledisk-capable system. -Dave

There are two 8340B Cal files in the files section, one has an IMD extension and the other has a TBZ extension. Neither will convert via Teledisk to make a working file to run on a Series 200 or 300

Correction to my last post. this is TP4 and TP3 from the good A11A4 This is the same for the bad unit, same time/div

It has been awhile and a spare 8566A RF unit was purchased to troubleshoot this problem. The 100 MHz cal signal displays as 133 MHz. I replaced the A11 YTO Loop Assy. The SA immediately worked

Interesting discussion! But I need to find the software and do the adjustments before I make the keep/return decision on this one. Keysight will calibrate it for me for just over $600 but won’t

There appears to be an oversite (bug) in the software. See : https://www.eevblog.com/forum/testgear/agilent-e7495-linux-root-account/ This is a very good discussion on the software and some hacks.

Hi and welcome No, sorry, it will not work as a tracking generator. As the 8350 is not synthesized, it will never be accurate on frequency. If you only want to check a filter or an antenna, you could

Hi, is it possible to connect together?HP 8592L spectrum analyzer + HP 8350B sweep oscillator to persuade them to work as a SA with tracking generator? I'm measurements newbie, so interested in any
