To ensure maximum power and to avoid erroneous readings: Always inspect fiber ends and make sure that they are clean as  explained below before inserting them into the port. EXFO is not responsible for damage or errors caused by bad fiber cleaning or handling.
Page 46 EXFO uses good quality connectors in compliance with EIA-455-21A standards. To keep connectors clean and in good condition, EXFO strongly recommends inspecting them with a fiber inspection probe before connecting them. Failure to do so will result in permanent damage to the connectors and degradation in measurements.
Page 47: Nulling Offsets
Preparing Your High Performance Power Meter for a Test Nulling Offsets Nulling Offsets Temperature and humidity variations affect the performance of electronic circuits and optical detectors, which can offset measurement results. To compensate for this offset, the unit is equipped with an offset nulling function.
Page 48 A red message appears beneath the power value of the channel for which you are performing a nulling. If you are using a multichannel power meter, you will notice that the other channels will stop reading power while nulling is in progress. IQS-1700...
Page 49 Preparing Your High Performance Power Meter for a Test Nulling Offsets To perform an offset nulling on all channels (two- and four-channel power meters): 1. Install the protective caps over all of the detector ports. 2. Under Nulling, click the All Channels button. Offset nulling values are applied to the channel until a new nulling is performed.
Page 50 Preparing Your High Performance Power Meter for a Test Nulling Offsets 3. Click OK to perform the offset nulling, or Cancel to exit. A red message appears beneath the power value of the channel for which you are performing a nulling. IQS-1700...
Page 51: Measuring Power
Measuring Power Power measurements can be displayed in two ways: absolute  relative  It is also possible to use a correction factor at specific wavelengths and to add an offset value to your power measurement. Displaying Absolute Power When in absolute power, measured values are displayed in either dBm or W units (pW, nW, W, mW...) and the displayed value represents the absolute optical power reaching the detector within specified uncertainty.
Page 52 6. Return to the Instrument function tab and click Absolute to activate the mode. An absolute power measurement in negative W units indicates that the nulling of the offset was improperly done. If this happens, repeat the offset nulling operation (see Nulling Offsets on page 39). IQS-1700...
Page 53: Measuring Relative Power
Measuring Power Measuring Relative Power Measuring Relative Power Power measurements can be displayed as a deviation from an absolute reference value. The relative power is particularly useful when performing loss measurements. Relative power is displayed in dB when the reference value is measured in dBm.

Page 59: Averaging Measurements
Measuring Power Averaging Measurements Averaging Measurements When the averaging function is enabled on the IQS-1700 High Performance Power Meter, the most recent measurement samples, for which you can set the number, are used to compute an unweighted average. This average is displayed as the measured value.
Page 60 Averaging button to activate the list. Average /Averaging lists To toggle between averaged and unaveraged power measurement: 1. If necessary, select the desired channel from the Instrument function tab. 2. Click the Averaging button to activate or deactivate it. IQS-1700...
Page 61: Recording Power Signal Variations
Recording Power Signal Variations The Min./Max. function allows you to record the extremes of a varying power signal when performing a continuous acquisition. For example, it could be used to determine the stability of a light source over time or to measure the polarization-dependent loss (PDL) of a passive component when combined with a polarization state controller.
Page 62 These can be stopped at any time by clicking Stop. If the timer is set, power measurements will stop automatically after the specified duration. Note: The remaining duration is indicated under the Start and Stop button. The Reset button will reinitialize the Min./Max. acquisition results in the data display. IQS-1700...
Page 63 Recording Power Signal Variations The results of the Min./Max. function are continuously updated in the matching lists. When a logarithmic scale is used, the Max.Min. calculation is made to continuously provides the difference between the two extremes. In a linear scale, the Min./Max. ratio is computed to provide valuable information.

This query returns the current wavelength in meters for the specified channel. Example(s) SENS:POW:WAV? See Also SENSe:POWer:WAVelength IQS-1700...
Page 179 SCPI Command Reference Product-Specific Commands—Description :SLINstrument:CATalog? Description This query returns a comma-separated list of <STRING RESPONSE DATA>, which contains the names of all channels of the module. If no channels are defined, a single null <STRING RESPONSE DATA> is returned. This is not affected by a *RST command.
Page 180 <STRING RESPONSE DATA> element. The list of <STRING RESPONSE DATA> contains the names of all channels in the module. The immediately following <NR1 NUMERIC RESPONSE DATA> formatted number is the associated channel number. Example(s) SLIN:CAT:FULL? See Also SLINstrument:CATalog? IQS-1700...
