For the reference input it does not state the need for a sine wave because there is no need.? Just like single purpose frequency counters do not require a sinewave. The reference out is a sine wave

Wow,? $1400 for a calibration is outlandish. If you run all your diagnostics, chances are your 8920 is working okay but may be off frequency, etc.. If your doing commercial work requiring a cal, you

Great! Thx for all input.?? Will build my own 10MHz low pass filter as per the article Robert linked to or just take the easy way out and purchase the one on eBay. I'll dig through my storage

I have used this one from ebay - about 3 dB insertion loss, about $10.50 - eBay item number:385415398319

Yes. I'd put it through a low pass filter though. The 8920 input is sensitive enough. Here is one example: http://www.w1ghz.org/small_proj/10MHz_Filter_for_GPS_Reference.pdf looks like same design

Fully agree even though I have not used Ricks services for actual repairs or mods but only for advice as well as Rick's excellent posts here in the group. I just wish we would have a similar workshop

I have a Spectracom GPS clock 8183A as my 10MHz frequence reference in my lab to my various instruments. I am interested in testing the Leo Bodnar Electronics?Precision GPS Reference Clock:

Does anybody have the glass filter that goes in front of the CRT on an 8921 they would like to sell? Mine was cracked when i got it. I am going to do the LCD display mod and i thought this would be a

Chris, Because you get the summary of messages and?because this Bessel thread?has consisted of several aspects,?it's not obvious what is new for you.? Is there something in particular you learned

Awesome! Learnt something today..

Correction:? that should be 2.0793 kHz (2079.3 Hz), not .20793 kHz.? Sorry about that. Burt, K6OQK

Hank, If you could give a step by step on how you accomplished this, it would be really appreciated, particularly how you were able to get the generator function to directly feed the receiver side

Hank, I got the attachment. That looks great.? I printed out the appropriate page and will give it a try as soon as I have some time in my shop.? Try it using a tone frequency of 2.0793 kHz.? The

Keith, The User Keys have to be programmed by you. You only need one such key for this setup (Global K1, K2, or K3).? Knob spinning or direct numerical entry comprise the other button pushes you'll

So what were the keys used. Keith

Forgot the attachment.

After several hours of fumbling around with the HP's menus, I got a SA display of the built in SG output at 146.00 MHz. At first I used a BNC jumper to get the SG into the SA, but then with more

Thanks Robert, Just let me know when if you find them. Bill M.

Sorry for the slow progress on looking for the boards. Not been to the storage unit yet. I did find a box of boards from a 8923 but none of the ones you need in that collection. Robert.
