DIG_Block_PG_Config 6534 timebase problem

[David Pettigrew]

The NI-DAQ documentation say you can use the following values in the DIG_Block_PG_Config function timebase parameter,

-3: 50 ns (653X devices only).
1: 1 µs.
2: 10 µs.
3: 100 µs.
4: 1 ms.
5: 10 ms.

Yet in the 6534 manual it says you set the timebase frequency to = 20MHz, 10MHz, 1MHz, 100kHz, 10kHz, 1kHz or 100Hz. This would appear that there are 7 timebase options supported by the card, but the software only has 6. The 10MHz (100ns) option is not listed in the DIG_Block_PG_Config documentation. I am wondering is the NI-DAQ documentation wrong and missing a value or am I limited to what the function will support.

Yes, this does seem to be inconsistent. Thanks for pointing this out! I'll go ahead and report this. You can still get a 10 MHz transfer rate though by specifying the 20 MHz timbase and using a timebase divisor of 2.
