Exchange Traces - Agilent Technologies ESA Series User's/Programmer's Reference

Remote Command Reference
TRACe Subsystem
This command does not allow setting all trace points to the same amplitude value
NOTE
by sending just a single value. If you need to set all trace points to the same value,
you must send the same value to each trace point.
Rawtrace data is available with UINT,16 or INT,32 formatting. It is unitless,
returns uncorrected ADC values, and is the fastest method of obtaining
measurement data.

Exchange Traces

:TRACe:EXCHange <trace_1>,<trace_2>
Exchanges 2 traces, point by point and leaves both in VIEW mode.
Example:
374
Suppose you are using a data format other then ASCII.
:TRAC:DATA TRACE1,#41604<binary trace
data><LF–EOI>
This sends the block of data values to trace 1. The block starts
with the header: #41604.
• The first digit in the header tells you there are 4 more digits
in the header.
• The 1604 means 1 thousand, 6 hundred, and 4 data bytes
follow the header.
• Divide this number of bytes by your current data format (4
for real,32). Then there are 401 trace points in the block.
• The line feed EOI is sent as the terminator when using GPIB.
Commands :MMEM:STOR:TRAC and :MMEM:LOAD:TRAC are
used to transfer trace data to, or from, the internal hard drive or
floppy drive of the instrument.
The number of points in a trace is specified by
[:SENSe]:SWEep:POINts . The trace data format is
determined by :FORMat[:TRACe][:DATA] , and the binary
data byte order is determined by :FORMat:BORDer .
If the parameter to the query is LLINE1 or LLINE2 , a very large
positive or negative value is returned at any point outside the
range of limit values. A large positive number is returned for an
upper limit, and a large negative value for lower limits. There is
no SCPI short form for parameters LLINE1|LLINE2.
Trace_1 choices are: TRACE1|2|3
Trace_2 choices are: TRACE1|2|3
:TRAC:EXCH TRACE3,TRACE2
