  • Page 99 Remote Control Commands Product-Specific Commands—Description SENSitivity:CORRection:OFFSet[:MAGNitude] Description This command sets an offset value that is applied when dB or dBm units are selected. Syntax SENS:CORR:OFFS[:MAGN]<space><numeric_value> [<space>DB] Parameters The <numeric_value> is an offset with dB units in the ±99.999 format. Example SENS:CORR:OFFS:MAGN 22.105 SENSitivity:FREQuency Description This command selects a data sampling rate.
  • Page 100 “99.999 dBm” format. Example SENS:POW:REF? SENSitivity:POWer:REFerence:DISPlay Description This command performs a new reference measurement for the current wavelength and changes the display to read relative power (dB units). Syntax SENS:POW:REF:DISP Example SENS:POW:REF:DISP PM-1100...
  • Page 101 Remote Control Commands Product-Specific Commands—Description SENSitivity:POWer:REFerence:STATe Description This command selects whether absolute (dBm) or relative power measurements are performed. Syntax SENS:POW:REF:STAT<space><boolean> Parameters The <boolean> value represents either dB or dBm “0” to set absolute mode “1” to set relative mode Example SENS:POW:REF:STAT SENSitivity:POWer:REFerence:STATe?
  • Page 102 SENSitivity:POWer:UNIT? Description This query returns the current measurement units. Syntax SENS:POW:UNIT? Response The response will be “0” if units are dBm “1” if units are watt “2” if units are dB “3” if units are delta watt Example SENS:POW:UNIT? PM-1100...
  • Page 103 Remote Control Commands Product-Specific Commands—Description SENSitivity:POWer:WAVelength Description This command selects a new operating wavelength. Syntax SENS:POW:WAV<space><numeric_value> [<space>NM] Parameters The <numeric_value> is an operating wavelength expressed in nanometers (nm). Any wavelength within the spectral range of the optical detector (at 1 nm resolution) may be selected. See Technical Specifications on page 65 for the exact spectral range of each detector type.
  • Page 104 Product-Specific Commands—Description SYSTem:VERSion? Description This query returns the current system software version. Syntax SYST:VERS? Response “EXFO E.O. Engineering PM-1100 Vxx.xx”, where xx.xx is the current product version. Note The *IDN? and SYST:VERS? queries are equivalent. They give the same result. UNIT:POWer Description This command changes the measurement display units.
