Measurement Accuracy And Speed - Agilent Technologies N1911A User Manual

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 Agilent
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 the sensor
C A U T I O N
user's guide.
The
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.
