Table 7. Trigger sources and modes
Specification
Single channel analog hardware trigger

Single channel analog software trigger

External-single channel digital trigger (TTL TRG input)

Digital pattern trigger

Counter/totalizer trigger

Single channel analog hardware trigger: The first analog input channel in the scan
is the analog trigger channel.
Input signal range: –10 V to +10 V max

Trigger level: Programmable (12-bit resolution)

Latency: 350 ns typical

Accuracy: ±0.5% of reading, ±2 mV offset max

Noise: 2 mV RMS typical

Single channel analog software trigger: The first analog input channel in the scan is
the analog trigger channel.
Input signal range: Anywhere within range of the trigger channel

Trigger level: Programmable (16-bit resolution)

Latency: One scan period (max)

External-single channel digital trigger (TTL trigger input):
Input signal range: –15 V to +15 V max

Trigger level: TTL-level sensitive

Minimum pulse width: 50 ns high, 50 ns low

Latency: One scan period max

Digital pattern triggering: 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, max

Counter/totalizer triggering: 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, max
