IF Upconverter Calibration Attenuator (Option 300

and Option UNG Only)

IF Upconverter Calibration Attenuator, available from the

Configuration Dialog Box, is used to set the signal level delivered to the

IF input of the first mixer. The first mixer’s IF input comes from the

300 MHz IF In connector on the hardware front panel (Option 300

Only), from the output of the I/Q modulator circuitry (Option UNG

Only), or both concurrently when the Allow IF and I/Q Concurrent

Operation check box is selected; this check box is available from the

Configuration Dialog Box.

The IF Upconverter Calibration Attenuator is used to select the amount

of attenuation to be applied to any incoming signal. This attenuation is

used to adjust the incoming calibration signal to a 0 dBm level. The IF

Upconverter Calibration Attenuator has a range of 0 to 30 dB in 2 dB

steps. This attenuator control can be used to increase the dynamic

range of the first mixer.
