a.
Enable the PFI5 line for output, as follows:
If you are using NI-DAQ, call
Select_Signal(deviceNumber, ND_PFI_5,
ND_OUT_UPDATE, ND_HIGH_TO_LOW)
.
If you are using LabVIEW, invoke the Route Signal VI with
signal name
set to
PFI5
and
signal source
set to
AO Update
.
b.
Set up data acquisition timing so that the timing signal for
A/D conversion comes from PFI5, as follows:
If you are using NI-DAQ, call
Select_Signal(deviceNumber, ND_IN_CONVERT,
ND_PFI_5, ND_HIGH_TO_LOW)
.
If you are using LabVIEW, invoke the AI Clock Config VI
with
clock source code
set to
PFI pin
,
high to low
, and
clock
source string
set to
5
.
c.
Initiate analog input data acquisition, which will start only
when the analog output waveform generation starts.
If you are using NI-DAQ, call
DAQ_Start
with appropriate
parameters.
If you are using LabVIEW, invoke the AI Control VI with
control code
set to
0
(start).
d.
Initiate analog output waveform generation.
If you are using NI-DAQ, call
WFM_Group_Control
with
operation
set to
1
(start).
If you are using LabVIEW, invoke the AO Control VI with
control code
set to
0
(start).
Timing and Digital I/O
12. What types of triggering can be hardware implemented on my
VXI-MIO Series module?
Digital triggering is supported by hardware on every
VXI-MIO Series module. In addition, the VXI-MIO-64E-1 and
VXI-MIO-64XE-10 support analog triggering in hardware.
13. What added functionality does the DAQ-STC make possible in
contrast to the Am9513?
The DAQ-STC incorporates much more than just 10 Am9513-style
counters within one chip. In fact, the DAQ-STC has the complexity
of more than 24 chips. The DAQ-STC makes possible PFI lines,
