Acquisition Memory System
On-FPGA FIFO Size
8 kilobytes
Record Length
Software selectable with 16-point resolution.
Record length must be a minimum of 128
points. There is no upper limit on the
maximum record length. It is limited by host
PC memory or disk size.
Number of Records
Software selectable from a minimum of 1 to a
maximum of infinite number of records
Pre-trigger depth
Fixed at zero
Post-trigger depth
Always equal to Record Length

Dynamic Parameters
Typical values measured using a randomly selected ATS9462 with Amplifier
Bypass Mode. Input was provided by a HP8656A signal generator, followed
by a 9-pole, 1 MHz band-pass filter (TTE Q36T-1M-100K-50-720B). Input
frequency was set at 1 MHz and output amplitude was 520 mV rms, which is
approximately 95% of the 550 mVrms full scale input in Amplifier Bypass
Mode.

Note that these measurements were made using raw data: no signal
averaging was used to artificially improve the results.
Further note that these dynamic parameters may vary from one unit to
another, with input frequency and with the full-scale input range selected.
