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 (i.e. begins the collection of new data). When the measurement is complete, it returns the result. These commands do not switch to another measurement.
To get the current measurement data, use the FETCh command.
:READ:DEMod:4x4:TIMEalign?
Title
Read Tx Time Alignment Data (4x4 MIMO configuration)
Description
Triggers a new Time Alignment measurement and returns the results. The Tx Time Alignment measurement must be the active measurement (specified by :CONFigure:DEMod TIMEalign). The current measurement can be queried using the command :CONFigure?
This command may not be supported if your instrument is loaded with older firmware, in which case you may upgrade to the current firmware version or use the :READ:DEMod:TIMEalign? command, instead. Refer to your instrument User Guide for instructions on updating firmware.
Data are returned as 14 comma‑delimited values: EVM (rms) in %, EVM (pk) in %, Ref Signal (RS) Power in dBm, Sync Signal (SS) Power in dBm, Carrier Frequency in MHz, Freq Error in Hz, and Freq Error in ppm, Cell ID. “--” is returned for the data that are not valid at that instance.

:READ:DEMod:CONStln?
Title
Read Constellation
Description
Triggers a new Constellation measurement and returns the results. The Constellation measurement must be the active measurement (specified by :CONFigure:DEMod CONStln). The current measurement can be queried using the command :CONFigure?
Data are returned as 10 comma‑delimited values: EVM (rms) in %, EVM (pk) in %, Ref Signal (RS) Power in dBm, Sync Signal (SS) Power in dBm, Carrier Frequency in MHz, Freq Error in Hz, Freq Error in ppm, Cell ID, the number of measurements used in the frequency error average (if on), and OSTP (OFDM Symbol Transmit Power) in dBm. “--” is returned for the data that are not valid at that instance.

Title
Read Tx Time Alignment Data
Description
Triggers a new Time Alignment measurement and returns the results. The Tx Time Alignment measurement must be the active measurement (specified by :CONFigure:DEMod TIMEalign). The current measurement can be queried using the command :CONFigure?
Data are returned as 9 comma‑delimited values: EVM (rms) in %, EVM (pk) in %, Ref Signal (RS) Power in dBm, Sync Signal (SS) Power in dBm, Carrier Frequency in MHz, Freq Error in Hz, and Freq Error in ppm, Cell ID. “--” is returned for the data that are not valid at that instance.

:READ:OTA:MAPping?
Title
Read OTA Coverage Mapping
Description
Triggers a new OTA Coverage Mapping measurement and returns the results. The OTA Mapping measurement must be the active measurement (specified by :CONFigure:OTA MAPping). The current measurement can be queried using the command :CONFigure?
Data are returned in six sets of comma‑delimited values. Each set consists of: Cell ID, Group ID, Sector ID, S‑SS Power, RSRP, RSRQ, and SINR.
Following the six sets of data are a final value for the Dominance. “‑‑” is returned for the data that are not valid at that instance.

Read OTA Scanner
Description
Triggers a new OTA Scanner measurement and returns the results. The OTA Scanner measurement must be the active measurement (specified by :CONFigure:OTA SCANner). The current measurement can be queried using the command :CONFigure?
Data are returned in six sets of comma‑delimited values. Each set consists of: Cell ID, Group ID, Sector ID, S‑SS Power, RSRP, RSRQ, and SINR.
Following the six sets of data are a final value for the Dominance. “‑‑” is returned for the data that are not valid at that instance.

:READ:OTA:TXTEst?
Title
Read OTA Tx Test
Description
Triggers a new OTA Tx Test measurement and returns the results. The OTA Tx Test measurement must be the active measurement (specified by :CONFigure:OTA Tx Test). The current measurement can be queried using the command :CONFigure?
Data are returned in three sets of comma‑delimited values. Each set consists of: Cell ID, Group ID, Sector ID, S‑SS Power, RSRP, RSRQ, and SINR.
Following the three sets of data are an additional set of four numbers: Dominance, Antenna count, Average Power, and Delta Power. “‑‑” is returned for the data that are not valid at that instance.

:READ:PFail?
Title
Read PASS/FAIL
Description
Triggers a new PASS/FAIL measurement and returns the results. It is a combination of the commands :ABORT; :INITiate; :FETCh:PFail? The PASS/FAIL measurement must be active. The current measurement can be queried using :CONFigure?

:READ:RF:ACLR?
Title
Read Adjacent Channel Leakage Ratio
Description
Triggers a new Adjacent Channel Leakage Ratio measurement and returns the results: Power levels for each channel (both absolute and relative). If the instrument is sweeping, it does not return until the sweep is complete. If the instrument is not sweeping and the current data are not valid it returns error –230. This could occur if there was a *RST immediately before the :FETCh? or if a measurement parameter was changed without an :INITiate.
Data are returned as 11 comma‑separated values: Main channel power, Left alternate channel power - relative and absolute, Left adjacent channel power - relative and absolute, Main channel power - relative and absolute, Right adjacent channel power - relative and absolute, and Right Alternate channel power - relative and absolute.
