Measurement Accuracy And Speed - Agilent Technologies N1913a User Manual

Measurement Accuracy and Speed

The power meter has no internal ranges. The only ranges you can set are
those of the U2000 Series USB power 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 in the sensor
C A U T I O N
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 U2000 Series USB power sensors.
The default is AUTO. In AUTO the range crossover value depends on the
sensor model being used.
