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.
