Operation Verification

I/Q Modulation Check

I/Q Modulation Check

NOTE

The I/Q modulation check is available only in the E4438C ESG vector signal generator with
Option 001/601 or 002/602.

1. Press

Preset

.

2. Press

I/Q

>

I/Q Calibration > Calibration Type DC User Full

until Full is highlighted.

3. Press

Execute Cal

to begin an I/Q calibration of the full frequency range of the signal generator.

The signal generator displays the message

I/Q Calibration in Progress

while the calibration is

occurring.

To abort the I/Q calibration, press

Abort Cal

. The message

I/Q Calibration in Progress

Aborting...

is displayed until the calibration is stopped completely.

NOTE

The I/Q calibration is stored in non-volatile memory and remains unchanged during a preset
or the power cycle of the signal generator.
