Hello,
I have a lovely 71100 spectrum analyzer that has little mileage on it. Unfortunately, the 70900A LO plugin has now died. Seems the YTO (5086-7747) is dead as there is no output signal. I would be very happy to get the required information to fix it. Could you please let me know how I can test it separately on the bench? I'd just need a connection diagram w/ voltages and the oscillator transistor model.
Thanks,
Adrian

Welcome to the forum!
I was able to locate an old 70900A Service Guide which I have scanned and posted to the web for you. It will show up on the Agilent.com 70900A product page in the next 24 hours. Refer to the troubleshooting sections in chapter 5.
I have also posted the manual at the following temporary link for your convenance. http://sa.tm.agilent.com/mms/70900A-Service-Guide.pdf
Unfortunately, 70900A is out of support so Agilent can not supply replacement parts.
Best Regards,
