Rigth, I have seen that info, (0.01% of center freqency + 2% of freqency
span + 5 x N MHz), but I quite don't understand it ...

If say I am measuring a 300 Mhz signal, and I have a span of say 500 Khz..

- What is the precision or error that I can expect ?

Any hands on experience with that spectrum analizer, and in special
regarding frecuency marker precision, will be welcomed.

Hi I am using a HP8592B to do RF measurements and the marker, after a
passed auto calibration, could be out 100 or 150 khz when measuring
signals over the 300Mhz range.

This spectrum analiser is a non synthetised VCO type, and I don't quite
know what frecuency measurement precision can be expected from it.

- Any experience on the marker frecuency precision on that type of
spectrum analiser?

Looking in a 1991 HP catalog, I see that you can expect a readout accuracy
of no better than 0.01% of center freqency + 2% of freqency span + 5 x N
MHz (this appears to be a term for the timebase accuracy). Keep in mind
that many spectrum analyzers are not precision measurement instruments.
