Keysight N9923-90001 User’s Guide 165VVM (Vector Voltmeter) Mode - Option 308VVM Mode SettingsThis setting survives a Preset and Mode Preset.How to set Resolution— Press Scale/Amptd— Then Resolution— Thenchoose:— 1 0.0 (default)— 2 0.00IF BandwidthReducing the IF receiver bandwidth reduces the effect of random noise on ameasurement. However, narrower IF bandwidths cause longer measurementtimes.For highest accuracy, Zero AFTER changing the IF Bandwidth. Learn more in“Zeroing” on page 167.How to set IF BW— Press BW 2— Then IF BW— Then choose from the following:300 Hz | 1 kHz | 3 kHz | 10 kHz | 30 kHzOutput PowerSet the power level out of the FieldFox to High, Low, or manually set powerlevel to a value between High and Low.Generally, the high power setting is used when measuring passive, high-lossdevices to place the signal farther from the noise floor. However, for devicesthat are sensitive to high power levels such as amplifiers, use the Low powersetting.For best measurement accuracy, use the Manual power setting at -15 dBm.After calibration, the power level can be decreased for amplifiers, or increasedfor higher dynamic range.How to set Output Power— Press Meas Setup 4.Power Level settings in this mode will NOT change Power Level settings inother modes. To help prevent damage to your DUT, use caution whenchanging modes with your DUT connected to the FieldFox test ports.
