There are contradictions in the test results: If you say that the VCO frequencies are correct (39.996MHz for LOW and 39.84Mz for HIGH), then this necessarily means that the VCXO is at precisely 40

Hi, I have accumulated quite a bit of 8530A/8510C stuff over the years. the 8530A stuff? I was going to use to experiment with an antenna range. Realistically it's never going to happen, and all the

Hi Jeremy, This is a great win. What is your overall impression of the E5052A? I have R& FSPN8 and 53100A but I would like something I can try to push to lower phase noise levels. I need below

Here is a more precise TP16 measurement. VCXO is Ok at 40.000 MHz

Is the test point on the picture correct ?

Hi Yves, Thank you for the details. I have some more questions. " For high band VCO must be 39.84Mz and VCO at 39.996MHz for lowband <16MHz." --> ?TP20 VCO. This part seems to work in my

Evening all. I'm new to the group and appreciate all the advice and wisdom on here. I'm now needing some assistance with an Agilent MSO6014A not booting up. I bought the 'scope, around year ago,

Great!? That's the best kind of repair; when you learn something in addition to getting it working again. Jim FordLaguna Hills, California, USA

Scan sent to wb2uaq. Incidentally, there should not be DC on the output—100 uf capacitor C18, in series with 39 Ohm resistor R35, connects the emitter of emitter follower Q7 to the output BNC

Back on this after a short break. I'm experiencing what Gary Appel described a few posts back. The SL1 VCO module on an extender (per prior photo) can be adjusted (two potentiometers, one controlling

Sorry for delay, For high band VCO must be 39.84Mz and VCO at 39.996MHz for lowband <16MHz. Divider: 4kHz for low frequency and 160kHz for high frequency. VCXO 40 MHz, your SPAN of Spectrum

Can you post a picture of these capacitors? -Dave -- Dave McGuire, AK4HZ New Kensington, PA

When I worked on the 8660's and plugins more than 25 years ago, I had short lengths of bus wires with smaller gauge wire soldered to them and then they covered with heat shrink.? This allowed

My VCO frequency is wrong is should be 39.840 MHz. 39.840 MHz divide by 40 is 996 KHz. I have a VCO frequency of 39.100 MHz. Divide by 40 : 977 KHz. -> The 2sd LO frequency I have. Can I manualy tune

Thanks David!? ? I replied to Jeremy.

Thanks Jeremy!? ?A scanned copy of the schematic diagram would be much appreciated. My email is wb2uaq@.... ( wb2uaq@gmail ) Maybe I can scan in something for you from my collection of manuals

VNA parameters used ?: - Frequency center 100 MHz - SPAN zero mode TP20 (VCO): RF signal is at 39.100 MHz, -1.3 dBm instead of 39.840 on your board for frequency >16 MHz *seems KO ?* RF signal is at

Hey Dave, According to the manual they're actually both electrolytics. Thanks for you kind word! Arnaud.

OK, great, thank you. I will compare my your measurement on my A12 board.
