Generator Menu
Generator On Off
Press to turn the tracking generator On or Off. The output power is turned on at the level that was previously set with the Output Power submenu key.
Output Power
Press to set the output power of the generator. The specified range is from – 80 dBm to 15 dBm. If the user has entered an external gain or loss value, that value will be added to the displayed value.
Generator Mode
Press to toggle the Generator Mode between CW and Tracking. In CW Mode, the output frequency is fixed and set by the CW Frequency submenu. In Tracking Mode, the output frequency is paired with the spectrum analyzer input sweeping frequency. The frequency range is set using the Freq main menu and submenu keys. Setting Generator Mode to Tracking will automatically, set Sweep Mode to NO FFT and Detection to Sample.
CW Frequency
Sets the frequency of the output when the Generator Mode is set to CW.

Ext Gain/Loss
Sets the tracking generator (GENERATOR/RF OUT) external attenuation or gain. Press the Ext Gain/Loss submenu key and select a value from 0 dB to 100 dB, then select either dB External Loss or dB External Gain. The Generator Gain/Loss setting (other than 0 dB) is displayed in the upper‑right corner after the Generator output power level.
The external attenuation or gain is also reflected in the displayed output power.
Power Statistics
Press to display the Tracking Generator Summary table displaying the spectrum analyzer received Maximum, Average, and Minimum power of each frequency range sweep. Only available with Generator Mode set to tracking.
Enhanced Generator Accuracy
Displays the Gen Power Accuracy submenu.
Enhanced Accuracy Calibration: Improves the output accuracy of the generator when turned on. The calibration can be done in both Tracking Generator and CW Generator modes. Changing the output power turns enhanced calibration OFF. (+Accy) is displayed after the Generator power level when Enhanced Accuracy is ON.
Matching Pads(3dB) Zero One Two: Sets the number of external 3 dB attenuators used during the Enhanced Accuracy Calibration procedure.
Additional Calibration Sweep: Pressing this key after Enhanced Accuracy Calibration is completed starts an additional set of calibration sweeps to improve the power accuracy level of the generator output.
Back

Normalize
Press to toggle Normalization On or Off. When turned On, a calibration process is started. Make a THROUGH connection between the tracking Generator Output and the Spectrum Analyzer Input connectors before performing normalization. For the most accurate results, use the same cables and adapters that will be used for the normalization as will be used for the measurement. The current state (Off or On) is underlined.
Relative Ref
Press to set the value of the top graticule line in dB relative to the THROUGH connection that was made when normalization was performed.
Relative Scale
Press to set the scale factor from 1 dB/division to 15 dB/division in 1 dB steps.
Transmission Statistics
Press to display the Transmission Measurement Statistics table displaying the received spectrum analyzer Maximum, Average, and Minimum relative power of each frequency range sweep.
Transmission Offset
Sets the offset for the normalized trace. Offset value is displayed in the Transmission Measurement Statistics.
