Hi,
I have a spectrum analyzer Agilent N9320, and it is measuring -5,4dB down of the real value.
I connected the REF OUT (signal 10MHz, 0dBm) that stays on rear of the equipment on the RF IN.
The signal measured is 10MHz, but the power is -5.40dBm.
I tested with another spectrum analyzer from ROHDE&SCHWARZ and a RF Signal Generator with the same config, 10MHz, 0dBm. The result was:
The spectrum analyzer Agilent measured 10MHz, -5,46dBm.
The spectrum analyzer ROHDE&SCHWARZ measured 10MHz, -0,3dBm.
Is anybody kwon what’s happening with equipment?
My friend says that this equipment there is a auto calibration. Where can I found this option?
Thank you.

It seems the N9320A/or B need a self calibration. Please find a BNC-T cable and follow the procedures below:
1. Connect the CAL OUT and RF IN ports in front panel with the BNC-T cable.
2. Press [Preset/System]>[Alignment]>[Align]>[ALL]
The calibration will take 20 seconds approximately. Then the analyzer is expected to be fine for test.
If the test result remains 5 dB lower, please contact cid_support@agilent.com for further help.
