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.


N is the 1st LO harmonic used for the front-end conversion. It is
always 1 for any frequency in the first band of coverage, so the
tolerance at 300 MHz would be +/- 5.055 MHz.

Rigth, so if in doing the measurement of frecuency at 300 Mhz with a span of
500Khz I get say 299.870 my unit is OK, rigth ?

I don't see those big errors of 5 Mhz.

Any pointers to the user manualfor that unit ?

Sure.

I don't see those big errors of 5 Mhz.

If the analyzer doesn't have a stabilization feature, and its frequency
accuracy is that good, it is pure luck. Don't count on it being that
close at any other frequency, or remaining that close at 300 MHz for
very long.

Any pointers to the user manualfor that unit ?

Try www.manualsplus.com for a hardcopy, or if a search at agilent.com
doesn't turn anything up, ftp://ftp.agilent.com/pub/manuals/ .
