X-Series signal generators installed in rack systems andpowered down with the system rack power switch rather than the instrument’s front panel switch display a Error -310due to the instrument not being powered down correctly.NoteTo define a user preset, set the instrument up as desired and press User Preset > Save User Preset.Makes the increment value of the current function the active entry.Utility >Instrument Adjustments The increment value and the step/knob ratio determine how much eachturn of the knob changes the active function value.For example, if the increment value of the active function is 10 dB and thestep/knob ratio is 50 to 1, each turn of the knob changes the activefunction by 0.2 dB (1/50th of 10 dB).To change the amount for each turn of the knob, modify the incrementvalue, the step/knob ratio, or both.For details on each key, use key helpas described on page 56.page 42.page 41.Executes the ALC Modulator Bias Adjustment. When usingthe ALC in open loop mode, this compensates for open looppower drift due to temperature and humidity.SCPI Commands::CALibration:ALC:MODulator:BIAS
