within each sensor. Sensor output corrected at a frequency of
measurement within rated range.

Operating: Temperature compensated for rated accuracy

from 0° to 50°C (32° to 122°F)

Storage: -20° to 70°C (-4° to 158°F)

1

For rated accuracy, no more than 1% AM harmonics -50dBc or less, terminating VSWR 2:1 or less.

2

Forward power is defined as power traveling from the source to the load. Measurement accuracy

is referenced to the load connector.

3

Reflected power is defined as power traveling from the load to the source. Measurement accuracy

is referenced to the source connector.

4

Calculated from forward and reflected power.
