Panther-H Modem
Panther-H is an intelligent frequency hopping transceiver developed by Racal (now Thales Group). Has a signature 8-burst SOC (Start Of Conversation) sync procedure.
This transceiver, when in frequency hopping mode, will begin with the 8-burst SOC. After a SOC, the modem will begin sending data using frequency hopping, typically covering a bandwidth of 64kHz, 128kHz, or 256kHz, but it can cover up to 2 MHzMegaHertz (MHz) 10^6 Hz. The SOC bursts each last 95ms, and the data bursts in freq hopping mode last about 121ms each. The SOC bursts stay on the same frequency for 8 bursts; they don't frequency hop. Frequency hopping begins when a connection is established between two parties and data begins to transmit.
The modem uses QPSKQuadrature Phase-Shift Keying (2 bits per symbol) at 2400 BdBaud (unit symbol Bd) is the unit for symbol rate or modulation rate in symbols per second.. For frequency hopping, the standard speed is 10 hops/s.
