MSM6996H/6996V/6997H/6997V/6998/6999
Transmit and Receive Level Adjustment (MSM6996H/V, MSM6997H/V)
a. Transformer of turns ratio 1 : 1
1:1
4WS
600 W

4WR
600 W
600 W
AG
R1 20 kW
1 AIN+
2 AIN–
3 GSX
600 W 5 AOUT
600 W Attenuator
When R1 is open and the attenuator is set at
0 dB,
4 WS maximum input level = +7.17 + LT
(dBm)
4 WR maximum output level = +1.15 – LT
(dBm)
LT : Transformer loss

300 W Attenuator
When R1 is open and the attenuator is set at
0 dB,
4 WS maximum input level = +10.18 + LT
(dBm)
4 WR maximum output level = +4.16 – LT
