| Abstract: |
| A switch network for signal transmission test is designed which is suitable for
microwave test system in ground station.Based on the design of switch network to
pologic structure,not only multi-access connection is implemented between instru
ment and tested system but also test cable calibration is implemented easily and
accu
rately by measuring looped cables group by group before solving equations.The sw
itch network controlled remotely by Local Aera Network(LAN) can be integrated in
the test system easily.The test results show that the design has strong agility
and reliability. |
