To run the gain calibration, do the following:
NOTE
. When you run the gain calibration during signal acquisition, the
calibration begins after the acquisition is completed.
1. Press the Cal key on the front panel (see Figure 4--7).
2. Press the Calibrate Gain side key.
The calibration runs. It takes several seconds to complete the process.
When you want to perform the gain, center offset, and DC offset calibration
together, press the Calibrate All side key.
3. If you press the Auto Calibration side key to select Yes , the calibration will
run automatically any time the analyzer gain drifts to an uncal state.
