7.2 Descriptions
7.2.1 Interface Card
This card has the following main functions:
1. Normalization of all the analog signals from various sensors/detectors and hand
them over to the CPU.
2. Implementation and management of hardware high-speed protection to protect
the machine.
3. Interfacement for telemetry and serial communication with the CPU
In particular:
1. Standardization reading directional coupler with digital trimmer SPI, rms and
peak detector.
2. Reading current/voltage.
3. High-speed protection on forward, reected and input power.
4. High-speed protection on PA current.
5. Gain control.
6. Fan control.
7. Power control (On/Off).
8. Generating the necessary power (+5V, +12V, -12V ...) to the card.
9. DB25 telemetry interface.
10. RS485/232.
11. Standardization of temperature measurement.
12. Interlock.
13. Management of display interface.
14. Common bus.
7.2.2 Input Card
This card is the rst circuit that the RF input signal meets entering into amplier. It
has a control bus and power supply, an input and an output connector. This card
works closely with the interface card to monitor the input and output signal and to
protect the entire amplier.
This card has the following main functions:
1. Measurement of input power.
2. Gain Control.
3. Input fast interruption.
