585User Manual 1335.5337.02 ─ 07
Usage: Asynchronous command
Manual operation: See "Vertical offset" on page 191
CALCulate:MATH<m>:ENVSelection <EnvelopeCurve>
Selects the upper or lower part of the input waveform for mathematic calculation, or a
combination of both.
Suffix:
<m>
.
1...5, index of the math waveform
Parameters:
<EnvelopeCurve> MIN | MAX | BOTH
*RST: BOTH
Usage: Asynchronous command
Manual operation: See "Envelope wfm selection" on page 185
CALCulate:MATH<m>:VERTical:SCALe:MODE
<VertSclMd>
Sets how the vertical scale is adapted to the current measurement results. By default,
scaling is done automatically to provide an optimal display. However, if necessary, you
can define scaling values manually to suit your requirements.
Suffix:
<m>
.
1...5, index of the math waveform
Parameters:
<VertSclMd> MANual | AUTO
*RST: AUTO
Usage: Asynchronous command
Manual operation: See "Scale mode" on page 191
CALCulate:MATH<m>:DATA:HEADer?
Returns the header of math waveform data. The header contains attributes of the
waveform.

Position Meaning Example
1 XStart in s -9.477E-008 = - 94,77 ns
2 XStop in s 9.477E-008 = 94,77 ns
3 Record length of the waveform in Samples 200000
4 Number of values per sample interval. For most
waveforms, the result is 1. For envelope waveforms,
it is 2. If the number is 2, the number of returned
values is twice the number of samples (record
length).
