RF LevelSMIQOFFSETLIMITInput value of the level offset of the RF output level compared to the inputvalue of the RF level indicated in the LEVEL header field. Input in dB (cf.Section 2.5.1, Level Offset). The status line indicates LEV-OFFST.IEC/IEEE-bus command SOUR:POW:OFFS 0Input value of level limitation. This value indicates the upper limit of the level atthe RF output connector. If a level above this limit is attempted to be set, awarning is displayed in the status line.IEC/IEEE-bus command SOUR:POW:LIM 16 dBmATTENUATOR MODE AUTO Normal operation. The attenuator switching mechanically switchesin steps of 5 dB, the switching points being fixed.IEC/IEEE-bus command :OUTP:AMOD AUTOFIXED Level settings are made in a range of somewhat over 20 dBwithout switching the attenuator (see section 2.5.2, "NoninterruptingLevel Setting"). The range of variation is fixedautomatically upon selection of this operating mode. The range isindicated in the ATTEN FIXED RANGE menu. With level settingsout of the indicated range, a warning is displayed.IEC/IEEE-bus command :OUTP:AMOD FIXELECTRONICLevel settings are made in a range of somewhat over 90 dB withoutswitching the attenuator (see section 2.5.2, "Non-interruptingLevel Setting"). The range of variation is fixed automatically uponselection of this operating mode. The range is indicated in theATTEN FIXED RANGE menu. With level settings out of theindicated range, a warning is displayed.This function is only available if the IQMOD module of versionVAR 4 or higher is installed (indication in UTILITIES - DIAG -CONFIG menu, IQMOD Var 4 required).IEC/IEEE-bus command :OUTP:AMOD ELECATTEN FIXED RANGEKNOB STEP USERKNOB STEPIndication of the level range in which the level is set without interruption in the"ATTENUATOR MODE FIXED" operating mode.Input value of the step width for level variation using the rotary knob. The RFlevel is varied in the step width entered if KNOB STEP is set to USER.IEC/IEEE-bus command SOUR:POW:STEP 1DECIMAL Variation step width according to the position of the digit cursor.USER User Defined, variation step width as entered under KNOB STEPUSER.POWER RESOLUTION Selection of resolution of LEVEL display. For level range -99.9 dBm to +16dBm the resolution for the level display can be set to 0.1 dB or 0.01 dB.POWER-ON STATESelection of the state the RF output is to assume after power-on of the unitRF OFFOutput is switched offPREVIOUS SETTING Same state as before switch-offIEC/IEEE-bus command :OUTP:PON ON1125.5555.03 2.48E-8
