Power Sensor Zero Drift

1. Within 1 hour after zero set, at a constant temperature, after a 24 hour

warm-up of the power meter.

Measurement Noise

2. The number of averages at 16 (for normal mode) and 32 (for x2 mode), at

a constant temperature, measured over a 1 minute interval and 2 standard

deviations. For Agilent E-series power sensors the measurement noise is

measured within the low range. Refer to the relevant power sensor manual

for further information.
