■PERFORMANCE TEST

4.Switch on the instruments.

a.Switch on the lightwave multimeter.

b.Configure the laser source.

■Set the laser source attenuation to 0 dB

■Set the wavelength to 1310 nm

■Note the actual (displayed) wavelength of the laser source in the test report

c.Switch on the attenuator.

■Set the wavelength to the wavelength of the laser source in the test report

d.Configure the optical head and interface module.

■Set the unit to dBm

■Set the averaging time, T, to 100 ms

■Set AUTO ranging on

■Set the wavelength to the wavelength of the laser source

■With the laser source and attenuator disabled, zero the power meter

e.Switch on the N3970A (DUT) for permanent operation, by holding the POWER key down for 3 seconds during turn-on

N3970A UM-1

until PERM is shown in the display.

■ Set the DUT to "dBm"

f.Make sure that all the instruments are warmed up.

5.Make the reference measurement.

a.Enable the laser source and the attenuator output.

b.Change the attenuation of the attenuator until the optical power meter displays -3.00 dBm.

Note In some cases the laser source will not be powerful enough to give -3.00 dBm. In such case, set the attenuator to 0 dB and correct the appropriate values in the test report.

■Note the setting of the attenuator for setting 1 in the test report

c.Change the attenuation of the attenuator until the optical power meter displays -20.00 dBm.

■Note the setting of the attenuator for setting 2 in the test report

d.Change the attenuation of the attenuator until the optical power meter displays -30.00 dBm.

■Note the setting of the attenuator for setting 3 in the test report

e.Change the attenuation of the attenuator until the optical power meter displays -50.00 dBm.

■Note the setting of the attenuator for setting 4 in the test report
