IF Gain Auto/Reference Level Auto Ranging
:DISPlay:WINDow:TRACe:Y[:SCALe]:LOG:RANGe:AUTO OFF|ON|0|1
:DISPlay:WINDow:TRACe:Y[:SCALe]:LOG:RANGe:AUTO?
This command enables and disables auto ranging. The speed benefits gained with
this command are realized only when in narrow resolution (digital) bandwidths.
The setting of auto range has no effect when in analog resolution bandwidths.
Factory Preset
and *RST: On
History: This command is available with firmware revision A.04.00 and
later.
Remarks: When using digital resolution bandwidths (RBW < 1 kHz) the
analyzer uses IF Gain auto ranging to set the optimum signal
gain for digital processing. This technique produces the greatest
measurement range without overloading the digital system. To
increase the measurement speed this IF Gain auto ranging may
be set to fixed mode. When in fixed mode, make sure the signal
