2 output CATV amplifier with AGC
E low noise Philips module. (Forward: BGY887+BGD814, Reverse BGY67A)
EQ, ATT have fixed or adjustable
Output splitter or coupler can plug change to make engineering debug more agile
More powerful, less consumption


SA822/SA822R is 2 way 2 output CATV signal amplifier with return path(optional)
Use Micro-tube pre-amplify and low noise Philips power doubler module(BGD814).
EQ, ATT have fixed or adjustable
Output splitter(FZ110) or coupler(FP204) can plug change to make engineering debug more agile
More powerful, less consumption
At the range of 750MHz (112.25~743.25MHz ) when testing the C/CTB and C/CSO, set 79 PAL-D imitate TV channels signal; Set 93PAL-D imitate TV channels signal at the range of 862MHz (112.25~855.25MHz).
Choose f1=65MHz, f2=63MHz and f3=57MHz to test when measuring index of max output level in upgo transmission.
The index of "Carrier to Second Order Intermodulation Ratio" is tested under the condition of 110dBuV output level, and choose f1=10MHz, f2=60MHz and f3=50MHz three point to test.
