Encryption

Only one type of encryption can be installed in each transmitter, and it must be done at the

factory. The choices are limited to:

• RCBC (Reverse Chain Block Ciphering)

• AES 128-bit

• AES 256-bit

Note

ASI input streams are not encrypted

8.7 RF Output Power

• High Power Mode: Enables PA and supplies output power of 8 W (+ 39 dBm)

NOTE: An optional 10W (+40 dBm) amplifier is also available)

• Low Power Mode: Enables PA and supplies reduced output power of 3 to 6 dB

• Impedance: 50 Ohms: 17 dB return loss, typical

• Protection: Transmitters will not be damaged by an infinite VSWR at any phase angle

at the RF output connector for an indefinite time.

NOTE: An optional 10W (+40 dBm) amplifier is also available)
