32 ATS9462 User Manual
Pipelined ADC
Each of the two ADCs on the ATS9462 is a pipelined flash
converter with a maximum conversion rate of 180 MS/s.
If you use an external clock, you must provide a free-running
clock to ensure reliable operation. You also must follow all
the timing specifications on the external clock as described in
Appendix A, Specifications.
Multiple Record Acquisition
The ATS9462 allows the capture of multiple records into the
on-board memory. This allows you to capture rapidly
occurring triggers in OCT, ultrasound or radar applications.
Note that pre-trigger data cannot be acquired using
ATS9462.
Specifying Record Length
Record Length is specified in number of sample points. It
must be a minimum of 128 points and can be specified with a
16-sample resolution.
Specifying Pretrigger Depth
ATS9462 cannot acquire pre-trigger data.
Specifying Record Count
User can specify the number of records that must be
captured into host PC memory. The minimum value must be
1.
Since the data is streamed to PC memory, there is no upper
limit on how many records you can capture in one acquisition.
