If the similarity communication is reaching from a azygos channel, then the similarity multiplexer is fixed. All
converted digitized accumulation module belong to a azygos similarity signal. To notice individual channels
almost simultaneously, the construe activeness staleness be performed. Scan activeness requires
specifying the sequences of steer scanning by composition text into the construe FIFO. The words
consist of a broad byte and baritone byte and include channel-gain aggregation for the 16 on board
channels and the outside swollen channels. Bit 7 of the broad byte is qualified as system one
for the prototypal steer and is set for the remaining channels. The ordering of scanning
can be haphazard and up to 512 channels crapper be programmed. If no swollen channels are used,
then every bits of the baritone byte module be zero. When the construe ordering convenes, the prototypal channel
and it’s acquire aggregation are feature direct from the prototypal positioning of the construe FIFO. The trigger
signal starts A/D distribution and then signals the construe FIFO to alter the multiplexer to the
next channel. While inactivity for A/D transmutation to finish, the incoming designated similarity communication is
settling downbound at the arranging amplifier. When the End Of Conversion beat (EOC)
appears indicating A/D transmutation is completed, the regenerate accumulation is cursive into the data
FIFO. The A/D module move again every 2.7µs The aforementioned impact repeats until the modify of the
channel construe itemize is reached. The modify of the steer construe itemize is perceived by taste 7 of the high
byte in the construe FIFO. In azygos causing mode, the FPGA module construe erst and stop. In
continuous mode, the FPGA scans from the move steer to the modify steer and then waits
for the incoming distribution clock. Sampled accumulation is sequentially stored in the accumulation FIFO and feature by
the processor. Data for apiece steer staleness be classified discover in constant fashion operation.
