Power Sensor Specifications
Definitions
Zero Set
In any power measurement, the power meter must initially be set to zero
with no power applied to the power sensor. Zero setting is accomplished
within the power meter by digitally correcting for residual offsets.
Zero Drift
This parameter is also called long term stability and is the change in the
power meter indication over a long time (usually one hour) for a constant
input power at a constant temperature, after a defined warm-up interval.
Measurement Noise
This parameter is also known as short term stability and is specified as
the change in the power meter indication over a short time interval
(usually one minute) for a constant input power at a constant
temperature.
