SIZE19 – 16
Waveform Capture Size - In Linear mode, this sets the number of data
points to be captured in a single sweep. In FIFO mode, this sets the
threshold for generating a service request interrupt or status bit. The
maximum size is 1 MSamples (2 Mbytes of data).

Waveform Capture Size - In Linear mode, this sets the number of data
points to be captured in a single sweep. In FIFO mode, this sets the
threshold for generating a service request interrupt or status bit. The
maximum size is 1 MSamples (2 Mbytes of data).

Unused
These bits are reserved for future use.

PRE19 – 16
Size of Pre-Trigger Data – In Linear mode, this sets the number of data
points to be stored before the trigger occurs. In FIFO mode, this register
is not used.
Minimum Value = 0
Maximum Value = (Capture Size) – 1
Pre-Trigger Points (0x16, 0x3E, 0x66, 0x8E, 0xB6, 0xDE) — Read & Write

PRE15 – 0
Size of Pre-Trigger Data – In Linear mode, this sets the number of data
points to be stored before the trigger occurs. In FIFO mode, this register
is not used.
Minimum Value = 0
Maximum Value = (Capture Size) – 1
Trigger Delay (0x18, 0x40, 0x68, 0x90, 0xB8, 0xE0) — Read & Write
D15 – D0
DELAY31 – 16
Trigger Delay - The trigger delay value is used to set the number of
samples between trigger occurrence and storing of data.
Minimum Value = 0
Maximum Value = 2
