PTC Commands 15-9 :READ Subsystem
S412E PM PN: 10580-00319 Rev. N 15-21
:READ:SIGAnalyzer?
Description: Triggers a new PTC Analyzer measurement and returns the numerical
results. It is a combination of the commands :ABORT; :INITiate;
:FETCh:SIGAnalyzer?
PTC Analyzer must be the active measurement (specified by
:CONFigure:SIGAnalyzer). The current measurement can be queried
using :CONFigure?
Data is returned as 8 comma-separated values in the following order
and format.
When the modulation type is set to 4FSK
([:SENSe]:DM:FORMat 4FSK):
Received Power (dBm as float or Watts as long long int or Volts as
long long int)
Frequency Error (Hz as float)
Mod Fid (% as float)
BER (% as float)
Symbol Dev (Hz as float)
Symbol Rate Error (Hz as float)
When the modulation type is set to DQPSK
([:SENSe]:DM:FORMat DQPSK):
Received Power (dBm as float or Watts as long long int or Volts as
long long int)
Frequency Error (Hz as float)
EVM (% as float)
BER (% as float)
IQ Imbalance (dB as float)
Symbol Rate Error (Hz as float)
Phase Error (degree as float)
Mag Error (% as float)
If there is no valid measurement data, the instrument will return
“--,--,--,--,--,--,--,--”.
The received power will be returned in the unit that is selected through
the Rx Units button on the front panel or with the command:
UNIT:POWer:RX. If the receiver unit has been set to dBm, the received
power is returned in dBm. If the unit is set to Watts, the received power
is returned in fW (10
-15
W). If the unit is set to Volts, the received power
is returned in fV (10
-15
V).
