There are 4 channels available for external digital data capture LabSat 3 Wideband. Recorded digital channel data is synchronized to each sample of recorded RF data; the maximum input frequency for each channel is 1 MHz.
The Digital menu allows CH1, CH2, CH3 & CH4 to be configured to record any of the following parameters:-
|1PPS||This is the 1 Pulse Per Second output from the internal GNSS monitor and will become active once the internal GNSS monitor has a position fix. Note, that if using battery power with the power save option enabled, the GNSS monitor will power-down after approx 30 seconds into the recording and therefore not be present in the recorded data. During replay, the recorded 1PPS signal will be output on pin 2 (DIGO) of the expansion connector.|
|CAN||CAN 1 and CAN 2 on the expansion connector (RLACS202) will be recorded on channel 1 & 2 of the LabSat 3 Wideband. See section CAN BUS for more details.|
|RS232||This will record an RS232 level signal input on pin 18 of the expansion connector. During replay, pin 17 of the expansion connector will output the recorded data at RS232 level. Because the RS232 signal is digitized directly, it is not necessary to configure baud rate.|
|DIGI1||Will record the digital state of pin 3 of the expansion connector. During replay, the signal will be re-created on pin 2 (DIGO) of the expansion connector. See section EXPANSION CONNECTOR for more details.|
|DIGI2||Will record the digital state of pin 8 of the expansion connector. During replay, the signal will be re-created on pin 6 (DIGO 2) of the expansion connector. See section EXPANSION CONNECTOR for more details.|
