TX output
Check transmission output
power voltage at following
conditions:
Range: 1000m
TX setting: 9-9-9
Tilt:
0
Stabilize.: OFF
TX weight: all 1
Measuring point
TP108-137
Measure peak-to-peak
voltage at 5ms from the
leading edge of the
transmission pulse.
There are 15 channels of
TX_P/N on each TRX
board. (Totally 600ch)
Fig 1 TX output power and B voltage
Normally, the output power voltage should read 1400Vp-p. However, it varies within ±15% because of
transducer impedance. B voltage is normally 120V at each transmission.
