<Operation>
Depending on the operation you select, one trace is subtracted
from another. The result is written to the first trace indicated in
the operation.
An operation is only available if both traces are actually turned
on.
(TRACE1-TRACE3)
(TRACE2-TRACE3)
(TRACE4-TRACE6)
(TRACE5-TRACE6)
*RST:
Trace mathematics are off.
Example:
//Subtract trace 2 from trace 1 and write the result to trace 1
CALC:MATH (TRACE1-TRACE2)
Manual operation:

Formats for Returned Values: ASCII Format and Binary Format
When trace data is retrieved using the
TRAC:DATA
or
TRAC:IQ:DATA
command, the
data is returned in the format defined using the
on page 419. The
possible formats are described here.
●
ASCII Format (FORMat ASCII):
The data is stored as a list of comma-separated values (CSV) of the measured val-
ues in floating point format.
●
Binary Format (FORMat REAL,16/32/64):
The data is stored as binary data (definite length block data according to IEEE
488.2), each measurement value being formatted in 16-bit/32-bit/64-bit IEEE 754
floating-point-format.
The schema of the result string is as follows:
#41024<value1><value2>…<value n>
with:
#4
Number of digits (= 4 in the example) of the following number of data bytes
1024
Number of following data bytes (= 1024 in the example)
<Value>
2-byte/4-byte/8-byte floating point value
Reading out data in binary format is quicker than in ASCII format. Thus, binary format
is recommended for large amounts of data.
