Total Readings per Partition
(total memory size)/(number of partitions)
When the non-volatile mode of memory is enabled, this number is reduced
by four readings.
Pre-Arm Data before the arm event can be stored in a circular-overwrite mode (per
partition) until the event occurs.

Signal Conditioning
A/D Converter 50Ω input, -1.0225V to 1.0230V range
Each channel contains a high-performance 12-bit, 20MSa/s A/D converter.
For best A/D performance (highest linearity and lowest noise), choose the
50Ω input port and select its ± 1 volt input range. Except as noted, this port
is used for A/D performance characteristics listed below. Due to amplitude
and frequency limitations of available test sources, and other practical
considerations, some parameters are specified only for this port and range.
Resolution
12 bits (including sign)
Codes from -2048 to +2047 indicate results as follows:
-2048 : amplifier overload (single-ended or differential inputs)
-2047 : not used
-2046 : normal-mode overload (negative)
-2045 : minimum on-scale reading
.
.
+2046 : maximum on-scale reading
+2047 : normal-mode overload (positive)
