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 following
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 shows the typical uncertainty
in making a relative power measurement,
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 transitioning
from the power level used as the reference
to the power level being measured.
