Timothy,
The 656x devices have a limit on the available data delay values based
on frequency. Between 25MHz and 50MHz there are "holes" in the
available delay range. Above 50MHz, the full 0 to 1 data delay is
valid. If you look in the specifications installed with NI HSDIO
for the NI 656x, on page 7, Figure 1, there is an illustration showing
how to compute what the valid range is for the frequency of interest.
For example, at 40MHz, valid values are:
0 to 0.2
0.3 to 0.7
0.8 to 1
In the error message posted below, you tried to input a value of 0.
71875 which is not within these ranges.
