Accuracy at full scale: 5W Range ±10% (F.S), 20W Range ±5% (F.S),200W Range ±5% (F.S), (Add -10% of full scale at 220 to 420MHz, add +10% of full scale at 450 to 525MHz) Minimum power at SWR measurement: 4W
Insertion loss: Less than 0.1dB (140 to 250MHz) Less than 0.2dB (400 to 470MHz) less than 0.3dB (525MHz)
