Agilent Technologies E9300 manual Measurement Accuracy and Speed, Setting the Range

Measurement Accuracy and Speed

Measurement Accuracy and Speed

The power meter has no internal ranges. The only ranges you can set are those of the HP E-series E9300 power sensors (and other HP E-series power sensors). With an Agilent 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.

Caution	To prevent damage to your sensor do not exceed the power levels
	specified in the section “Maximum Power” on page 35.
	The Agilent 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 HP E-series E9300 power sensors (see Table 1).

Table 1 Sensor Ranges

Sensor	LOWER range	UPPER range
E9300/1/4A	-60 dBm to -10 dBm	-10 dBm to +20 dBm
E9300/1B	-30 dBm to +20 dBm	+20 dBm to +44 dBm
E9300/1H	-50 dBm to 0 dBm	0 dBm to +30 dBm

The default is “AUTO”. In AUTO the range crossover value depends on the sensor model being used (see Table 2).

Table 2 Range Crossover Values

E9300/1/4A	E9300/1B	E9300/1H
-10 dBm ±0.5 dBm	+20 dBm ± 0.5 dBm	0 dBm ± 0.5 dBm
