Advantest R3477 9kHz to 13GHz spectrum analyzer

[mjames]

Hi there. I have a R3671 and it is reading about 1.2 dBm low across all ranges. Do you have the service password for the unit and how much do you think is needed to correct for an error like this? When I try to do a Cal, I get the error IF Input Level Out of Range [-2544].

Warm Regards,
