Setting Up Your Variable Attenuator

Variable Attenuator

Basic Settings

Setting the Drift Tolerance

The drift tolerance setting is only available for the self-adjusting modules
and is only applicable for the

Power Tracking

function (see

Using the

Power Tracking Function (Self-Adjusting Modules)

on page 56).

When you use the power tracking function, the internal power meter
monitors the output power level and constantly adjust the attenuation to
ensure that the output power does not exceed the limits set (drift
tolerance). For example, if the power of the source used for the test drifts
over time, the attenuation is adjusted so that the output power remains
within the preset limits.
