N8480 Series Thermocouple Power Sensor Specifications (continued)

Switch point data

Switching point is applicable for standard

N8480 Series power sensors only.

The N8480 Series power sensors have

two power measurement ranges; a lower

range and upper range. The power meter

automatically selects the proper power

range. To avoid unnecessary switching

when the power level is near switching

point, a Switching Point Hysteresis has

been added.

Switching point hysteresis: 0.5 dB typical

Example of switching point hysteresis on

N8481/2H power sensors, this hysteresis

causes the lower range to remain selected

until approximately 17.5 dBm as the power

level is increased, above this power the

upper range is selected.

The upper range remains selected until

approximately 16.5 dBm as the signal level

decreases, below this power the lower

range is selected.

Sensors, data sheet (5989-9333EN).
