Zero Test

Specification

Electrical Characteristics
Accuracy: Zero set (Digital settability of zero)
*This performance limit is determined by the zero set specification of the power sensor used in the
measurement plus the measurement noise. The range calibrator has a zero set specification of
±0.05 mW. The calibrator measurement noise specification is 110 nW at 16 averages. At 512
averages a noise multiplier of 0.24 is required, giving a measurement noise specification of
0.0264 mW (0.24x512).

Description

After the power meter is initially calibrated and zeroed, the change in the
digital readout is monitored. This test also takes drift and noise into account,
since drift, noise and zero readings cannot be separated.
