MATH<x>:SPECTral?
Examples
MATH1:SPECTRAL? might return the spectral setup values for MATH1
as follows:
:MATH1:SPECTRAL:MAG DB; PHASE DEGREES; GATEPOS
0.0000E+00; GATEWIDTH 1.9996E-06; REFLEVEL 4.4587+01;
REFLEVELOFFSET2.2360E-01; SPAN 1.2500E+09; CENT ER
6.2500E+08; RESBW 1.00 02E=06; WINDOW GAUSSIA N; SUPPRESS
-3.5000E+01; UNWRAP 0; LOCK 0
.
MATH<x>:SPECTral:CENTER
This command specifies or returns the center frequency of the spectral analyzer
output data span 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 then entering a Center Freq value.

Syntax
MATH<x>:SPECTral:CENTER <NR3>
MATH<x>:SPECTral:CENTER?
Related Commands
MATH<x>:SPECTral:SPAN, HORizontal:MODE:SAMPLERate
Arguments
<NR3> is the desired frequency of the spectral analyzer output data span in hertz.
Examples
MATH3:SPECTRAL:CENTER 10.09E6 sets the center frequency to the closest
value it can attain to 10.09 MHz.
MATH2:SPECTRAL:CENTER? might return :MATH2:SPECTral :CENTER
10.0900E+06
, indicating that the center frequency
is currently set a t 10.09 MHz.
MATH<x>:SPECTral:GATEPOS
This command sets or returns the position of the center of the gate, which is used
as the data input 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 then entering
aGatePosvalue.
