Ref Level
Opens an edit dialog box to enter the reference level in the current unit (dBm, dBµV,
etc).
The reference level is the maximum value the AD converter can handle without distor-
tion of the measured value. Signal levels above this value will not be measured cor-
rectly, which is indicated by the "IFOVL" status display.
Remote command:
DISPlay[:WINDow<n>]:TRACe<t>:Y[:SCALe]:RLEVel on page 750
Y-Axis Max
Opens an edit dialog box to specify the maximum value of the y-axis in either direction
(in Volts). Thus, the y-axis scale starts at -<Y-AxisMax> and ends at +<Y-AxisMax>.
This command is only available if the display configuration for the I/Q Analyzer is set to
"I/Q Vector" or "Real/Imag (I/Q)", see "Display Config" on page 447.
Range
Opens a submenu to define the display range of the level axis.
Range Log 100 dB ← Range
Sets the level display range to 100 dB.
Remote command:
Logarithmic scaling:
DISP:WIND:TRAC:Y:SPAC LOG, see DISPlay[:WINDow<n>]:TRACe<t>:Y:
SPACing on page 749
Display range:
DISP:WIND:TRAC:Y 100DB, see DISPlay[:WINDow<n>]:TRACe<t>:Y[:SCALe]
on page 749
Range Log 50 dB ← Range
Sets the level display range to 50 dB.
