Programming Examples
Example 3 - Measuring and I ncluding the Insertion Loss
b. Connect both instruments to the electric supply.
c. Switch on both instruments.
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. For the second part of the example reconfigure the hardware to
include the attenuator:
a. Disconnect the source from th e senso r, and connect it to the
input of the attenuator.

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