MATH:DEFINE <QString>
MATH:DEFINE?
Arguments
<QString> specifies a math waveform, and can be one of the following:TDS1001,
TDS1002, TDS1012, TDS2002, TDS2012 and TDS2022 models; TDS210 and
TDS220 models (firmware V2.00 and above) with a TDS2MM measurement
module.
CH1+CH2 CH1-CH2 CH2-CH1 FFT (CH<x> [, <window>])TDS2004, TDS2014
and TDS2024 models; TDS224 model with a TDS2MM measurement module.
CH1+CH2 CH3+CH4 CH1-CH2 CH2-CH1 CH3-CH4 CH4-CH3 FFT (CH<x>
[, <window>])TDS210 and TDS220 models, firmware below V2.00 with a
TDS2CMA communications module.
CH1-CH2 CH2-CH1 CH1+CH2 -CH1 -CH2 TDS210 and TDS220 models
(firmware below V2.00) with a TDS2MM measurement module.
CH1+CH2 (to subtract, invert one of the waveforms through CH<x>:INVert, and
then add) FFT (CH<x> [, <window>])TDS210 and TDS2 20 models (firmware
V2.00) and above with a TDS2CMA communications module.
CH1+CH2 CH1-CH2 CH2-CH1 TDS224 model with a TDS2CMA
communications module.
CH1+CH2 CH3+CH4 CH1-CH2 CH2-CH1 CH3-CH4 CH4-CH3 TDS1000B,
TDS2000B, TDS2000C, and TPS2000 Series.
CH1+CH2 CH3+CH4 (4-channel models) CH1-CH2 CH2-CH1 CH3-CH4
(4-channel models) CH4-CH3 (4-channel models) CH1*CH2 CH3*CH4
(4-channel models) FFT (CH<x>[, <window>])
For FFT, the optional <window> argument is HANning, FLATtop, or
RECTangular.
Examples
MATH:DEFINE "CH1+CH 2" sets the math waveform so that it d isplays the sum of
channel 1 and channel 2.
