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

Measurement Accuracy and Speed

The power meter has no internal ranges. The only ranges you can set are those of
the U8480 Series USB thermocouple sensors. With an U2000 Series power sensor
the range can be set either automatically or manually. Use autoranging when you
are unsure 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 sensor user's guide. The U2004A 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 U8480
Series USB thermocouple sensors.

U2000H, U2001H, U2002H
U2000B, U2001B
The default is AUTO. In AUTO the range crossover value depends on the sensor
model being used.
