Table 2-25: Math Commands (cont.)
Command
Description
MATH[1]:SPECTral:NYQUISTFreq? Returns the Nyquist frequency of the FFT
math waveform
MATH[1]:SPECTral:WINdow Sets or returns the window function for math
waveform spectral input data
MATH[1]:TYPe
Sets or returns the math w aveform mode
type
MATH[1]:VERTical:POSition Sets or r eturns the vertical position of the
currently selected math type
MATH[1]:VERTical:SCAle Sets or returns the vertical scale of the
currently selected math type
MATH[1]:VERTical:UNIts? Returns the math waveform v ertical units
Measurement Command Group
Use the commands in the Measurement Command Group to control the automated
meas
urement system.
Up to four automated measurements can be displayed on the screen. In the
com
mands, these measurement readouts are named MEAS<x>, where <x> is the
measurement number.
In a
ddition to the four displayed measurements, the measurement commands let
you specify an additional measurement, IMMed. The immediate measurement
has no front-panel equivalent. Immediate measurements are never displayed.
Because they are computed only when needed, immediate measure ments slow the
waveform update rate less than displayed measurements.
Whether you us e displayed or immediate measurements, use the VALue query to
obtain measurement results.
Measurement commands can set and query measurement parameters. You
can assign some parameters, such as waveform sources, differently for each
measurement. Other parameters, such as reference levels, have only one value,
which applies to a ll measurements.
