IF Calibration (Option 300 Only)

IF Upconverter Level Calibration, available from the Pull Down

Calibration Menu, is used to calibrate the IF Upconverter. The

IF Upconverter is available on instruments with Option 300 only.

Calibrate IF Upconverter

The Calibrate IF Upconverter button is used to perform the calibration

at the selected frequency and attenuator settings that are specified.

Restore Factory IF Upconverter Calibration

The Restore Factory IF Upconverter Calibration button can be used to

return to the original factory calibration values. All values from any

previous user calibrations will be lost

IF Upconverter Calibration Frequency

The IF Upconverter Calibration Frequency is used to select the

frequency where a calibration is performed.

The IF Upconverter calibration is only valid for synthesizer frequencies

between 2 GHz </= 20 GHz. The IF Upconverter calibration cannot be

used for synthesizer frequencies from 10 MHz < 2 GHz.

For synthesizer frequencies from 10 MHz < 2 GHz, a Power Search may

be used to improve level accuracy with ALC off. Alternately, the

IFAttenuator, available from the pull down View menu by selecting

Configuration, can be adjusted in 2 dB steps to obtain the correct level

within +/- 1 dB; above 2 GHz or with ALC on, this is unnecessary.

IF Upconverter Calibration Attenuator

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.
