Command Description R&S FSH-K1
1157.3564.12 30 E-8
CTRACE (Complex Trace Data)
This command reads out the raw (= uncorrected) magnitude and phase values in alphanumeric format.
The magnitude unit is dBm, the phase unit is radiants. A complex trace consists of 301 magnitude and
301 phase values. If In DTF mode CTRACE will return 1024 magnitude and 1024 phase values.
Example:
get<cr>
0<cr>
ctrace<cr>
‘readout magnitude and phase values
0<cr>
‘responds parameter ok
-103.22,-106.88,-96.27,.....
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.
CTRACEBIN (Complex Trace Data Binary)
This command reads out the raw (= uncorrected) magnitude and phase values in binary format.
A complex trace consists of 301 magnitude and 301 phase sample values . If In DTF mode CTRACE
will return 1024 magnitude and 1024 phase sample values.
Each sample consists of 4 bytes with the LSB send first.
Example:
get<cr>
0<cr>
ctracebin<cr>
‘readout binary complex trace data
0<cr>
‘responds parameter ok
<sample><sample>....
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.
MATHMODE (Math Mode)
This command defines the math mode used for analyzer measurements.
Value Math Mode
0 Math mode OFF
1 Memory trace – Trace
2 Trace – Memory trace
Example:
set<cr>
0<cr>
mathmode,1<cr>
‘set math mode to “mem. trace – trace”
0<cr>
‘responds parameter ok
