E-Series E9300 Average Power Sensor Specifications
(continued)
Effects of change in
temperature on linearity
Note: If the temperature changes
after calibration and you choose not
to re-calibrate the sensor, the follow-
ing additional power linearity error
should be added to the linearity specs
in Table 9.
For small changes in temperature:
The typical maximum additional
power linearity error due to small
temperature change after calibration
is ±0.15%/°C (valid after zeroing the
sensor).
For large changes in temperature:
Refer to Table 10.

Figure 2. Relative mode power measurement linearity with an EPM Series power meter,
at 25 °C ±10 °C (typical)
Figure 2 shows the typical uncertainty
in making a relative power measure-
ment, using the same power meter
channel and same power sensor
to obtain the reference and the
measured values, and assumes that
negligible change in frequency and
mismatch error occur when transi-
tioning from the power level used as
the reference to the power level being
measured.
