HP8568B Marker measurement error.
« 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?
