Explanation
Any analog input channel can be software programmed as the analog trigger channel,
including any of the analog expansion channels.
 Input signal range: -10 V to +10 V maximum
 Trigger level: Programmable (12-bit resolution)
 Latency: 350 ns typical, 1.3 µs max
 Accuracy: ±0.5% of reading, ±2 mV offset maximum
 Noise: 2 mV RMS typical
Any analog input channel can be selected as the software trigger channel.
 Input signal range: Anywhere within range of the trigger channel
 Trigger level: Programmable (16-bit resolution)
 Latency: One scan period (maximum)
A separate digital input is provided for digital triggering (TTLTRG).
 Input signal range: -15 V to +15 V maximum
 Trigger level: TTL level sensitive
 Minimum pulse width: 50 ns high, 50 ns low
 Latency: One scan period maximum
8-bit or 16-bit pattern triggering on any of the digital ports. Programmable for trigger on
equal, not equal, above, or below a value.
 Individual bits can be masked for "don't care" condition.
 Latency: One scan period, maximum
Counter/totalizer inputs can trigger an acquisition. User can select to trigger on a frequency or
on total counts that are equal, not equal, above, or below a value, or within/outside of a
window rising/falling edge.
 Latency: One scan period, maximum
