Measurement Accuracy And Speed; Setting The Range - Keysight N1913 User Manual

3 Using E9300 E-Series Power Sensors

Measurement Accuracy and Speed

The power meter has no internal ranges. The only ranges you can set are those of
the E9300 E-Series power sensors (and other Keysight Technologies E-Series
power sensors). With an E-Series E9300 power sensor the range can be set either
automatically or manually. Use autoranging when you are not sure of the power
level you are about to measure.
To prevent damage to your sensor do not exceed the power levels specified in
CAUTION
the sensor user's guide. The
excess of the maximum value (5 VDC) can damage the sensing diode.

Setting the Range

There are two manual settings, LOWER and UPPER. The LOWER range uses the
more sensitive path and the UPPER range uses the attenuated path in the E9300
E-Series power sensors.

The default is AUTO. In AUTO the range crossover value depends on the sensor
model being used.
