LMR Master™ S412E Programming Manual : NBFM Commands : :READ Subsystem
 
:READ Subsystem
This set of commands combines the ABORt, INITiate and FETCh commands. It aborts any current triggering sequence and sets the trigger state to idle. It then initiates a new active measurement (for example, begins the collection of new data). When the measurement is complete, it returns the result. These commands will not switch to another measurement.
To prepare for a new measurement, use the CONFigure command. To get the current measurement data, use the FETCh command.
:READ:COVerage?
Description
Triggers a new NBFM Coverage measurement and returns the numerical results. It is a combination of the commands :ABORT, :INITiate, and :FETCh:COVerage? NBFM Coverage must be the active measurement (specified by :CONFigure:COVerage). The current measurement can be queried using :CONFigure?
Data are returned as seven comma-separated values in the following order and format:
RSSI (dBm as float)
THD (% as float)
SINAD (dB as float)
ExtSINAD (dB as float)
Latitude (radian as float)
Longitude (radian as float)
UTC Date (month/day/year as char)
UTC Time (hour:minute:second as char)
The instrument returns “--” for each value with invalid measurement data.

:READ:QUIeting?
Description
Triggers a new NBFM Quieting measurement and returns the numerical results. It is a combination of the commands :ABORT, :INITiate, and :FETCh:QUIeting? NBFM Quieting must be the active measurement (specified by :CONFigure:QUIeting). The current measurement can be queried using :CONFigure?
Data are returned as two comma-separated values in the following order and format:
Measured Voltage (float) and Reference Voltage (float).
If there is no valid measurement data, the instrument will return “--,--”.

:READ:SIGAnalyzer?
Description
Triggers a new NBFM Analyzer measurement and returns the numerical results. It is a combination of the commands :ABORT; :INITiate; :FETCh:SIGAnalyzer?
NBFM Analyzer must be the active measurement (specified by :CONFigure:SIGAnalyzer). The current measurement can be queried using :CONFigure?
Data are returned as 11 comma-separated values in the following order and format:
Carrier Power (dBm as float or Watts as long long int or Volts as long long int)
Carrier Frequency (Hz as float)
Deviation (Hz as float)
Mod Rate (Hz as float)
SINAD (dB as float)
THD (% as float)
Occ BW (Hz as float)
ExtSINAD (dB as float)
CTCSS (string)
DCS (string)
DTMF (string)
The instrument returns “--” for each value with invalid measurement data.
Please note that 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. If the unit is set to Volts, the received power is returned in fV.
Note: This command is not affected by the squelch level set using the front panel.

:READ:SNDRatio?
Description
Triggers a new NBFM SINAD measurement and returns the numerical results. It is a combination of the commands :ABORT, :INITiate, and :FETCh:SNDRatio? NBFM SINAD must be the active measurement (specified by :CONFigure:SNDRatio). The current measurement can be queried using :CONFigure?
Data are returned as 1 value in the following order and format:
Measured SINAD (dB as float).
If there is no valid measurement data, the instrument will return “--”.
