Using the Attenuator

 

Example, Setting the Calibration

 

 

NO T E

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 MODE and then LOSS,

 

and EXEC).

 

b. Reconfigure the hardware to include the attenuator:

 

i. Disconnect the source from the sensor, and connect it to

 

the input of the attenuator.
