5 Using E9300 E-Series Power Sensors
198 Keysight N1911A/1912A User’s Guide
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.
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.
CAUTION
To prevent damage to your sensor do not exceed the power levels specified in
the sensor user’s guide.
The
E9304A sensor is DC coupled. DC voltages in excess of the maximum value
(5 Vdc) can damage the sensing diode.
