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-ArmData 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)
