Title: HP8568B Marker measurement error.
Post by: Johnny10 on October 11, 2019, 09:53:59 am

I have an 8568B Spectrum analyzer that seems to work displaying frequency.
However when using marker to find that frequency I get an erroneous number.
Example: 760MHz signal is measured as 440MHz.

What circuitry controls these measurements?

Can you do a short video showing what you are talking about?
