R&S FSP Instrument Functions
Analyzer Mode
REF LEVEL The REF LEVEL softkey allows the reference level to be input in the currently active
unit (dBm, dBµV, etc.)
Remote command:
DISP:WIND:TRAC:Y:RLEV -60dBm
RANGE LOG
100 dB The RANGE LOG 100 dB softkey sets the level display range to 100 dB.
Remote command:
DISP:WIND:TRAC:Y:SPAC LOG
DISP:WIND:TRAC:Y 100DB
RANGE LOG
MANUAL The RANGE LOG MANUAL softkey activates the manual entry of the level display
range. Display ranges from 1 to 200 dB are allowed in 10 dB steps. Inputs which are
not allowed are rounded to the next valid value.
The default setting is 100 dB.
Remote command:
DISP:WIND:TRAC:Y:SPAC LOG
DISP:WIND:TRAC:Y 120DB
RANGE
LINEAR The RANGE LINEAR softkey selects linear scaling for the level display range of the
R&S FSPr. In addition, it opens a submenu for selecting % or dB for the scaling.
When linear scaling is selected, the % scaling is first activated (see also RANGE
LINEAR dB softkey).
Remote command:

Markers are displayed in the selected unit; delta markers are displayed in % refer-
enced to the voltage value at the position of marker 1.
Remote command:
DISP:WIND:TRAC:Y:SPAC LIN
RANGE
LINEAR dB
The RANGE LINEAR dB softkey selects linear scaling in dB for the level display
range, i.e. the horizontal lines are labelled in dB.
Markers are displayed in the selected unit; delta markers are displayed in dB refer-
enced to the power value at the position of marker 1.
