Calibration

Calibration

Perform these routines to optimize the analyzer performance:

Gain calibration

Center offset calibration

DC offset calibration

IF

fl

atness calibration

Display brightness adjustment

Each item is explained in this section.

Cal Menu

Use the

CAL

key to calibrate the analyzer.

Figure 11: Calibration menu structure

The Cal menu contains the following controls:

Calibrate All.

Performs all possible calibration operations.

Calibrate Gain.

Calibrates the internal gain steps. (See page 16,

Calibrating

Gain

.)

Calibrate Center Offset.

This calibration cancels a center offset. (See page 17,

Calibrating Center Offset

.)

Calibrate DC Offset.

This calibration cancels DC offset in baseband. (See

page 17,

Calibrating DC Offset

.)

Calibrate IF Flatness.

Calibrates the IF (intermediate frequency)

fl

atness. (See

page 18,

Calibrating IF Flatness (RSA3408B Only)

.)
