Notes:

1) Specifications assume differential input single channel scan, 200 kHz scan rate, unfiltered.

2) Accuracy specification is exclusive of noise. Measurements w

ere taken at P1.

3) Inputs shorted to Signal Ground (SGND). 8192 samples.

Input Sequencer

Analog, digital and counter inputs can be scanned synchronously based either on an internal programmable timer, or

an external clock source. Analog and digital outputs can be synchronized to either of these clocks.

Scan Clock Sources: 2

• Internal, programmable from 5 µs to 5.96 hours maximum in 1 µs steps

• External, TTL level input up to 200 kHz maximum

Programmable Parameters per Scan: channel (random order), gain, unipolar or bipolar

Depth: 16,384 locations

On-boa

rd Channel-to-Channel Scan Rate: 5 or 10 µs per channel, programmable

Expansion Channel Scan Rate: 5 µs,10 µs, or 1000 µs per channel, programmable

External Acquisition Scan Clock Input

Maximum Rate: 200 kHz

Clock Signal Range: 0V to +5V

Minimum Pulse Width: 50 ns high, 50 ns low

External Sync Ports

Number of External Sync Ports: 2, on rear panel

Maximum Number of Units to be Synchronized: 4 units, scan-synchronous (post trigger)

Maxi

mum Length of Sync Cables: 15 feet (4.57 m), total for all cables

Triggering

Trigger Sources: 6, individually selectable for starting and stopping an acquisition. Stop acquisition can occur on

a different channel than start acquisition; stop acquisition can be triggered via modes 2, 4, 5, or 6 described

below. Pre-trigger is supported with fixed or variable pre-trigger periods.

1. Single-Channel Analog Hardware Trigger

Any analog input channel, including any of the analog expansion channels, can be software programmed as

the analog trigger channel.

Input Signa

l Range: -10V to +

10V max

Trigger Level: Programmable, 11-bit resolution

steresis: Programmable, 11-bit resolution

Latency: 5 µs max
