Calibrating The Hp 3563A - HP 3563A Operating Manual

C a l ibratin g t h e H P 3563A
The HP 3563A's calibration routine adjusts the gain and phase accuracy and common-mode
rejection of the input channels to comply with the analyzer's specifications. It starts by applying a
known signal (internally) to the input channels. Next, it measures this known signal and compares it
to the channels' responses. From these, it generates calibration constants that it uses to adjust the
input circuitry. During calibration, the analyzer displays "CALIDRATION IN PROGRESS".
If a calibration failure should occur (the failure message will be displayed on the screen), refer
servicing to qualified personnel. A list of HP Sales and Support Offices is included at the end of this
manual.
You can choose auto cal, which calibrates on a regular schedule, or single cal, which calibrates only
when you desire. To make the choice, press CAL to display the following softkeys:
AUTO
ON OFF
SINGLE
CAL
Note
If auto cal is enabled, the analyzer follows the calibration schedule shown in table
7-6, even if both channels are digital. In this case, you can turn auto cal OFF - the
analyzer does not use calibration results for digital channels.
Selects auto cal; see table 7-6 for the auto cal schedule. This softkey is
reset to ON at power-up.
Pauses any measurement and performs a single calibration. Do a single
cal before a measurement if auto cal is off and the measurement must
provide calibrated results.
