The Command Encoder/Exciter (CEE) is a rack-mount unit ideal for test and verification of Flight Termination Receivers (FTR) and/or Tone Receiver/Decoders. It accepts a universal AC power input, and it generates a modulated RF output carrier signal adjustable in 100kHz steps from 406MHz – 450MHz from suitable for interrogation all RCC 319 compliant IRIG FTRs. The CEE is available in 3-tone, 8-tone, or 20-tone configurations and can transmit up to 6 tones simultaneously. Additionally, CEEs are available with an adjustable RF output power from 0 to -127dBm (1dB steps) or with a fixed RF output power of 5W (CEE-5W). All IRIG tones can be switched ON/OFF independently. An optional remote control interface is also available, which enables control in Local Mode using the front panel switches or Remote Mode using an RS-232 or GPIB interface.
