TRACEBIN (Trace Data Binary)
This command reads out the trace data in binary format.
Each sample consists of 4 bytes with the LSB send first. The 4 bytes represent the measured power in
the current unit. The sample values are multiplied to provide the highest resolution possible.
Value Binary values
0 dBm * 1000
1 dBmV * 1000
2 dB \ V * 1000
3 dB \ V/m * 1000
4 dB \ A/m * 1000
5 dB * 1000
6 Volt * 1000000
7 Watt * 1000000000
8 Degrees * 1000
9 Seconds * 1000000
A trace consists of 301 samples. If the Auto Peak detector is used, both Max and Min values are
returned (602 samples: 301 min values then 301 max values).
Example:
get<cr>
0<cr>
tracebin<cr>
‘readout binary trace data
0<cr>
‘responds parameter ok

Note: In Tracking Generator with measurement modes Smith Chart, Phase or Vector Magnitude
the trace will also be sent in unit degrees. First 301 magnitude values and 301 additional
phase values. Phase values are wrapped or unwrapped depending on Wrapphase.
TRACETOMEM (Copy current trace to memory)
This command stores the current trace to memory.
Example:
cmd<cr>
0<cr>
‘responds parameter ok
tracetomem<cr>
‘store the current trace to memory
0<cr>
‘responds parameter ok
