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).
