Measurement Accuracy and Speed

The power meter has no internal ranges. The only ranges you can set are those of
the Keysight E-Series E9300 power sensors (and other Keysight E-Series power
sensors). With a Keysight 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
CAUTION
in the datasheet.
The Keysight 9304A sensor is DC coupled. DC voltages in 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
Keysight E-series E9300 power sensors (see
Table 2-1
Sensor
E9300/1/4A
E9300/1B
E9300/1H-50
The default is "AUTO". In AUTO the range crossover value depends on the sensor
model being used (see
Table 2-2
