M AT H VA R : VA R < x >
Arguments
<QString> quoted string argument is the mathematic al expression that defines
the waveform.
Examples
MATH2:DEFINE "CH1+CH2" adds the Channel 1 and Channel 2, storing the
results in Math 2 waveform.
MATH1:DEFINE? might return
:MATH1:DEFINE "CH2*REF2" as the expression that defines Math 1 waveform.
MATH<x>:FILTer:MODe
This command or query sets or returns the filter risetime parameter.
Group
Math
Syntax
MATH<x>:FILTer:MODe {CENTered|SHIFt ed}
MATH<x>:FILTer:MODe?
Arguments
CENTERED sets the value at any point to the average of that point in the source
waveform and N points on either side of that point.
SHIFTED sets the value at any point to the average of that point in the source
waveform and 2N points before that in the source waveform. This shifts a rising
edge to the right side of the screen. Shifted mode is sometimes called a causal
filter since the value at any point is not caused by points after it in time.
Examples
MATH1:FILTER:MODE SHIFTED sets the filter mode to shifted.
MATH1:FILTER:MODE? might return :MATH1:FILTER:MOD E CENTERED,
indicating that the filter rise time parameter is set to CENTERED mode for Math
1 waveform.
