MATH<x>:SPECTral:GATEWIDTH
Arguments
<NR3> is the gate position. Units are represented in seconds, with respect t o
trigger position.
Examples
MATH1:SPECTRAL:GATEPOS —2e8 specifies the position of the edge of the gate
used as the data input to the spectral analyzer. The –2e–8 specifies that the center
of the gate is 2e–8 seconds before (to the left of) the trigger.
MATH2:SPECTRAL:GATEPOS? might r eturn :MATH2:SPECTRAL:GAT EPOS
0.0000E+00
, indicating that the gate position is set to zero (the trigger p osition).
MATH<x>:SPECTral:GATEWIDTH
This command s ets or returns the gate width input, in seconds, to the spectral
analyzer for the specified math waveform. The math waveform is specified by x,
which ranges from 1 through 4. This command is equivalent to selecting Spectral
Setup from the Math menu and entering a duration value in the Gate D ur box.

MATH<x>:SPECTral:GATEPOS
Arguments
<NR3> is the time across the 10-division screen in seconds.
Examples
MATH1:SPECTRAL:GATEWIDTH 1.0E-3 sets the gate width input to the spectral
analyzer at 1 ms.
MATH3:SPECTRAL:GATEWIDTH? might return :MATH3:SPECTRAL:GATEWIDTH
1.0000E-03
, indicating that the gate width to the spectral analyzer is set to 1 ms.
