Function
Access
Connector
Accepts either a TTL signal to start
waveform generation, or provides an
output to synchronize—or
trigger—other devices at a certain
time within waveform generation.
Input/Output
PFI 0
Routes signals from the PXI
backplane clock, PXI trigger lines,
or a divided-down version of
the internal NI 5404 clock.
Output
REF OUT
Accepts a PLL Reference clock from
an external source and can frequency
lock the NI PXI-5404 Sample clock
timebase to the external Reference
clock.
Input
REF IN
NI PXI/PCI-5412/5421/5422/5441
The NI 5412 is a 100 MS/s, 20 MHz, 14-bit arbitrary waveform generator. The NI 5421 is a 100 MS/s,
43 MHz, 16-bit arbitrary waveform generator. The NI 5422 is a 200 MS/s, 80 MHz, 16-bit arbitrary
waveform generator. The NI 5441 is a 100 MS/s, 43 MHz, 16-bit arbitrary waveform generator with
onboard signal processing (OSP). These devices have up to five connectors—four SMB connectors and
one 68-pin male VHDCI connector, as shown in the following figure. Signal descriptions are listed in
the following table.
