For rated accuracy, no more than 1% AM harmonics -50dBc or less, terminating VSWR 2:1 or less.
Forward power is defined as power traveling from the source to the load. Measurement accuracy

is referenced to the load connector.

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

is referenced to the source connector.

Calculated from forward and reflected power.
