triggers to occur at an arbitrary future time (future time events), or clocks
of arbitrary frequencies (with high and low times in multiples of 10ns). It
is also possible to program the start and ending time of a clock generated in
this way.
Refer to Table 3-6 for a list of destinations for synchronized time clocks
and future-time events.
Routing Signals
The NI PXI-6682 has versatile trigger routing capabilities. It can
route signals to and from the front panel, the PXI star triggers, and
the PXI triggers. In addition, the polarity of the destination signal can be
inverted, which is useful when handling active-low digital signals.
The NI PXI-6682 also can route a 10 MHz clock from
CLKIN
to the PXI
10 MHz reference clock. The NI PXI-6682 can route the TCXO, or PXI
10 MHz reference clock to
CLKOUT
.
Figure 3-4 summarizes the routing features of the NI PXI-6682.
The remainder of this chapter details the capabilities and constraints of
the routing architecture.
