Soft Front Panel Help
I/Q Calibration (Option UNG Only)
I/Q External Source Adjustments Dialog Box
The I/Q External Source Adjustments Dialog Box is used for the
following:
Selecting the I/Q input signals for the I/Q modulator circuitry
Adjusting the gain, offset, and quadrature of the I/Q input signals
paths
Compensating for impairments due to external I/Q source
generators
From this dialog box, you can select an I/Q signal that is normal,
swapped, or a test tone. You can adjust the gain of both I and Q input
signals through individual attenuators, and you can apply adjustments
to the calibration settings.
I/Q Input
The I/Q Input is used to select the way in which the I and Q input
signals are supplied to the synthesizers I/Q modulator circuitry.
When set to Normal, the signal that is physically connected to the I
Input on the synthesizers hardware front panel is used as the
I input signal, and the signal that is physically connected to the Q
Input on the synthesizers hardware front panel is used as the
Q input signal.
