4 Operating the Optical Power Meter Cleaning and Connecting Optical Fibers IMPORTANT To ensure maximum power and to avoid erroneous readings: ³ Always clean fiber ends as explained below before inserting them into the port. EXFO is not responsible for damage or errors caused by bad fiber cleaning or handling. ³ Ensure that your patchcord has appropriate connectors. Joining mismatched connectors will damage the ferrules. To connect the fiber-optic cable to the port: 1.
Operating the Optical Power Meter Nulling Electrical Offsets Nulling Electrical Offsets The offset nulling process provides a zero-power reference measurement, thus eliminating the effects of electronic offsets and dark current due to detectors. EXFO recommends performing a nulling before every test session.
Operating the Optical Power Meter Measuring Absolute Power Measuring Absolute Power Press dBm/Watt to display the absolute power of the signal received at the detector port. dBm/Watt is also used to toggle between dBm and watts measurement units. When using watts measurement units, the Optical Power Meter will automatically use pW, nW, μW, or mW, according to the power of the signal.
Operating the Optical Power Meter Relative Power Relative Power In relative mode, the Optical Power Meter compares the power of the signal received at the detector port to a preset reference value in dBm or watts. The relative power is equal to the absolute power minus the reference value, therefore ³ a negative measurement indicates that the received power is below the reference value, and ³ a positive measurement indicates that the received power is above the reference value.
Operating the Optical Power Meter Relative Power A delta symbol indicates that the PM-1100 is in relative mode and measuring in watts. Unit of measurement for the relative power Relative power nW nW Reference value Unit of measurement for reference value When you access relative mode, the Optical Power Meterdisplays the last reference value entered at the current wavelength.

Syntax MMEM:ACQ:DATA:RECA:VALUE? Parameters The parameter represents the memory location from which to recall the measurement data (out of the 1024 available). Response Measurement data saved in the specified memory location in the “±999.999E±99” format.
Remote Control Commands Product-Specific Commands—Description MMEMory:ACQuisition:DELete Description This command clears the 1024 memory locations reserved for the acquisition data. Syntax MMEM:ACQ:DEL MMEMory:ACQuisition:DELAy Description This command changes the delay parameter for the acquisition setup. Syntax MMEM:ACQ:DELA Parameters The parameter is the delay before the acquisition starts in the “HHH,MM,SS” format (the maximum delay is 999 hours, 59 minutes, 59 seconds).
Remote Control Commands Product-Specific Commands—Description MMEMory:ACQuisition:SAMPles Description This command changes the samples parameter for the acquisition setup. Syntax MMEM:ACQ:SAMP Parameters The parameter is the number of samples to be set for the acquisition setup. If an invalid parameter is entered, the closest valid parameter will be entered instead.
Remote Control Commands Product-Specific Commands—Description READ[:SCALar]:POWer:DC? Description This query returns the measurement currently read by the PM-1100 (whether the unit is in absolute power or relative mode). Syntax READ[:SCAL]:POW:DC? Response A measurement in the “±999.999E±99” format. To know the current measurement units, use the SENS:POW:UNIT? query.
Remote Control Commands Product-Specific Commands—Description SENSitivity:AVERage[:STATe] Description This command activates or deactivates data averaging. Syntax SENS:AVER[:STAT] Parameters The < boolean > parameter can be “0” averaging is disabled “1” averaging is enabled Example SENS:AVER:STAT 1 SENSitivity:AVERage:STATe? Description This query returns a value indicating whether data averaging is enabled or disabled.
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] [DB] Parameters The 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.
Remote Control Commands Product-Specific Commands—Description SENSitivity:FREQuency:CATalog? Description This query returns a list of available sampling rates. Syntax SENS:FREQ:CAT? Response List of available sampling rates in the “40.0;20.0;10.0;5.0;1.0;0.5;0.1” format Example SENS:FREQ:CAT? SENSitivity:POWer:REFerence? Description This query returns the reference power for the current wavelength.
Remote Control Commands Product-Specific Commands—Description SENSitivity:POWer:REFerence:STATe Description This command selects whether absolute (dBm) or relative power measurements are performed.
Remote Control Commands Product-Specific Commands—Description SENSitivity:POWer:UNIT Description This command changes the measurement units. Syntax SENS:POW:UNIT Parameters The can be “0” or “DBM” “1” or “W” “2” or “DB” “3” or “DW” Example SENS:POW:UNIT DBM SENSitivity:POWer:UNIT? Description This query returns the current measurement units.
Remote Control Commands Product-Specific Commands—Description SENSitivity:POWer:WAVelength Description This command selects a new operating wavelength. Syntax SENS:POW:WAV [NM] Parameters The 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.
Remote Control Commands 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.
