Connecting Signals
Each DIO, PFI, and clock channel of the NI digital waveform
generator/analyzer connects to a corresponding pair of leads on the
NI SHC68-H1X38 cable.
The NI SHC68-H1X38 cable is separated into two bundles of 19 channels,
and each channel is split into a pair of leads for connecting the signal and
its associated ground. Table 1 describes the channels and shows how they
are grouped by bundle.
