Specifications (continued)
Switching point
The U2000 Series power sensors have two measurement paths: a low power path and a high power path, as shown in the table below.
Each power sensor automatically
selects the proper power level path.
To avoid unnecessary switching when
the power level is close to the switch-
ing point, switching point hysteresis
has been added.
Offset at switching point:
≤ ± 0.5% (≤ ± 0.02 dB) typical
Switching point hysteresis:
± 0.5 dBm typical
Power accuracy
Average only Mode Power Accuracy
Specifications valid with the following conditions:
• After zeroing
• Number of averages = 1024
• After 30 minutes of power-on warm-up
Normal Mode Power Accuracy
1. This accuracy is essentially a combination of linearity, instrumentation accuracy, and traceability to absolute accuracy at 50 MHz, 0 dBm.
2. The accuracy for –7 to +1 dBm (U2000/1/2A), +3 to +11 dBm (U2000/1/2H), and +23 to +31 dBm (U2000/1B) power level will be dominated by
3. It is advisable to perform external zeroing on the U2000 Series power sensor for power measurement level below –30 dBm. During the external

sensors: Switching point for the
U2000/1/2/4A sensors is at –7 dBm.
Hysteresis causes the low power
path to remain selected until approxi-
mately –6.5 dBm as the power level
is increased. Above this power, the
high power path is selected. The high
power path remains selected until
approximately –7.5 dBm is reached
as the signal level decreases. Below
this power, the low power path is
selected.
