:DISPlay[:WINDow]:TRACe:X[:SCALe]:SM
SCale
Function
Sets parameters of the current display scale to
the measurement scale.
Syntax
:DISPlay[:WINDow]:TRACe:X[:SCALe]:S
MSCale
Example
:DISPLAY:TRACE:X:SMSCALE
Explanation • The following parameters are initialized based
on the display scale after this command has
been executed.
CENTER, SPAN, START, STOP
• This is a sequential command.
:DISPlay[:WINDow]:TRACe:X[:SCALe]:SP
AN
Function
Sets/queries the span of the X-axis of the
display scale.

+2.00000000E-008
Explanation • For the AQ6375/AQ6375B, to set using the
wavenumber, do not add any units when
in Wavenumber mode, and just enter the
numerical value.
• This is a sequential command.

Explanation • For the AQ6375/AQ6375B, to set using the
wavenumber, do not add any units when
in Wavenumber mode, and just enter the
numerical value.
• This is a sequential command.
:DISPlay[:WINDow]:TRACe:X[:SCALe]:STOP
Function
Sets/queries the stop wavelength of the X-axis
of the display scale.

:DISPlay[:WINDow]:TRACe:Y:NMASk
Function
Sets whether to mask the display of waveforms
the level of which is at or below a set threshold
level or queries the condition of whether the
relevant waveform display is masked.
Syntax
:DISPlay[:WINDow]:TRACe:Y:NMASk<wsp
><NRf>[DB]
:DISPlay[:WINDow]:TRACe:Y:NMASk?
<NRf> = Threshold level [dB] (–999: Masking
function OFF)
Example
:DISPLAY:TRACE:Y:MASK -999
:DISPLAY:TRACE:Y:MASK? ->
-9.99002
Explanation • The display of waveforms the level of which is
at or below this parameter will be masked.
To turn off the mask function, set the threshold
level to –999.
• This is a sequential command.
