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 approxi-
mately 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.
