Reference Level Auto Ranging
:DISPlay :WINDow :TRACe :Y[ :SCALe] :LOG :RANGe :AUTO OFFi ON~0i 1
: DISPlay : WINDow : TRACe : Y [ : SCALe ] : LOG : RANGe :AUTO ?
This command enables and disables auto ranging.
Factory Prese t
and *RST: On
Remarks :
With Option 1DR, Narrow Resolution Bandwidths, th e
reference level is normally auto-ranged. This results in
a wider dynamic range measurement at a slower
measurement speed. Using this command to disabl e
auto ranging results in faster measurements and bette r
resolution but reduces the available dynamic range .
NOTE
Internally to the instrument, the reference level may change ,
depending on instrument settings and input signals present . However ,
the reference level shown on the display does not change when thi s
command is used .
Trace Y -Axis Amplitude Scaling
:DISPlay :WlNDow :TRACe :Y[ :SCALe] :PDIVision <rel ampl>
: DISPlay : WINDow : TRACe : Y [ : SCALe ] : PDIVis ion ?
Sets the per-division display scaling for the y-axis when y-axis units are
set to amplitude units .
Factory Preset
and *RST : 10 dB
Range : 0.1 to 20 .0 dB
Default Unit : dB

Trace Y -Axis Frequency Scalin g
:
DISPlay : WINDow : TRACe : Y [ :SCALe] : PDIVis ion : FREQuency <freq>
:DISPlay :WINDow :TRACe :Y[ :SCALE: ] :PDIVision :FREQuency?
This command sets the per-division display scaling for the y-axis,when
the y-axis units are set to frequency units, such as when looking at FM
deviation with the command [ : SENSe ] : DEMod :VIEW [ : STATe ]
