Using the Attenuator
Example, Setting the Calibration
NOTE Under normal circumstances you should leave the instruments to 
warmup. (The multimeter needs around 20 minutes to warmup. The 
attenuator needs around 45 minutes with the shutter open to warmup.) 
Warming up is necessary for accuracy of the sensor, and the output 
power of the source.
d. Connect a patchcord from the source to the input of the 
sensor.
2. Measure the insertion loss of the Hardware setup:
a. On the multimeter:
i. Set the wavelength for the sensor to that of the source.
ii. Activate the source, by pressing the gray button on its 
front panel.
iii. Start the loss application (press M
ODE and then LOSS, 
and E
XEC).
b. Reconfigure the hardware to include the attenuator:
i. Disconnect the source from the sensor, and connect it to 
the input of the attenuator.

ii. Connect a patchcord from the output of the attenuator to 
the sensor.
