Using the Power Meter Linearity Verification Tool

DWDM Passive Component Test System 157

Selecting the DUT and Reference Power Meter

In order to perform a linearity verification, you need to specify which

power meter has to be tested (DUT) and which power meter will act as a

reference.

Note: You must have performed the hardware initialization and the nulling

before being able to select power meters.

³ To select the DUT, use the up/down arrows next to the Power meter:

box from the DUT panel.

³ To select the reference power meter, use the up/down arrows next to

the Reference Power Meter: box from the Settings panel.

IMPORTANT

Any power meter can be used as a reference power meter. However,

to avoid erroneous results, make sure that the module you intend

to use as a reference has been properly calibrated.
