Wavecom hardware decoders W-PCI and W-PCIe have two separate A/D and channel down converters. With this hardware design W-PCI and W-PCIe can be used for simultaneous dual channel decoding. For every card installed in the PC, two decoder instances are available for independent use. They are listed in the device selector (via the menu Configuration -> W-PCIe Device …) with two different but continuous serial numbers (SN#).
One W-PCIe card is listed with two instances for simultaneous decoding.
With this feature the user can wire two totally different signals from the receiver to the two inputs of different channels, e.g., AFIF#1, IF70#1a, IF70#1b of the channel 1 and AFIF#2 and IF70#2 of the channel 2 for simultaneous decoding. The two decoding instances don’t interfere with each other. This simultaneous feature enables a compact decoding and signal analysis setup.
Simultaneous decoding on one W-PCIe card: the 1st instance is decoding STANAG-4285 on AFIF#2 (input channel 2) and the 2nd instance is decoding SAT-C-TDM on IF70#1b (input channel 1).
