Calibration

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.

Figure 13: 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.

Calibrating DC Offset

The DC offset calibration cancels DC offset that appears at 0 Hz in the baseband
(RSA3408B: DC to 40 MHz, RSA3300B: DC to 20 MHz). When you change the
amplitude setting and the DC offset is too obvious, run the DC offset calibration.
