Hello ALL,
When i am callibrating the analyzer, i have sometimes problems with SRQ 110 (cal: res bw amp fail).
In the diagnose screen Display Cal Data all the numbers are ok, but the 3 dB BW AMP 10 Hz gives 1.52.
Do you have an adjustments manual for option 130 NBW?
The next question is that after a hard reset at the beginning screen i don't can choose any more on the softkey between spectrum analyzer and cable tv analyzer( i have options 004, 101, 102, 130, 021, at the backside option number H80).
Do you know what the reason is and i also cannot find it back in the manuals?
With kindly regards,
Hifreak

Resolution bandwidths <1 kHz are the narrow resolution bandwidths and there is a hardware switch from A11 and A13 RBW boards to the optional A130 board. If the 10 Hz RBW is having the issue, there is not a manual adjustment. The cal amplitude routine automatically calibrates the NRBW’s via DAC control. If that is the issue, the board may need replacing. The part number is 08590-60352 and is actually still available through www.agilent.com/find/parts Make sure the ≥ 1kHz BW amplitude corrections in the display cal table are reasonable as well. BW’s from 3 MHz down to 1 kHz can be adjusted on the A11 and A13. The adjustment procedure is on the web in the service guide at www.agilent.com and search on “8591E”.
The CATV analyzer softkey is active when the measurement personality has been downloaded from the personality card. My guess is this software no longer exists in the instrument. Do you have the option H80 measurement personality? If not, you may be able to call Agilent in the U.S.A. at 1-800-829-4444 and they will sell you a replacement if it is missing.
