3 Using E9300 E-Series Power Sensors
116 N1913/1914A EPM Series Power Meters 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 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.
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.
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.
