Calibrating Center Offset
When you display a spectrum and no input signal is present, a spurious emission
at the center frequency may appear regardless of frequency settings. The center
offset calibration cancels those spurious emissions. If the spurious emission is
too obvious when you narrow the span, run the calibration.
NOTE
. Option 03 only. When you input I and Q signals from the rear panel
connectors, set the IQ input signal level to zero externally.
When the spurious emission appears at
the center of the screen with no input
signal, run the center offset calibration.
Figure 1- 19: Center offset
To run the center offset calibration, do the following:
1.
Press the
CAL
key on the front panel.
2.
Press the
Calibrate Center Offset
side key.
The calibration runs. It takes several seconds to complete the process.
