Switching Point
The U2000 Series USB power sensors have two paths, a low power path
covering –60 dBm to –10 dBm, and a high power path covering –10 dBm to
+20 dBm. The power meter automatically selects the appropriate power level
path. To avoid unnecessary switching when the power level comes close to the
–10 dBm point, a Switching Point Hysteresis is added. This hysteresis causes
the low power path to remain selected until approximately –9.5 dBm has been
reached. When the power level increases above –9.5 dBm, the high power path
will be selected. The high power path remains selected until approximately
–10.5 dBm has been reached. When the power level decreases below
–10.5 dBm, the low power path will be selected.
Switching point linearity: Typically <±0.5% (<±0.02 dB)
Switching point hysteresis: Typically 0.5 dB
