Trigger sources and modes
Table 7. Trigger sources and modes
Input scan trigger sources
 Single channel analog hardware trigger
 Single channel analog software trigger
 External-single channel digital trigger (TTL TRG input)
 Digital pattern trigger
 Counter/totalizer trigger
Input scan triggering modes
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 maximum
 Trigger level: Programmable (12-bit resolution)
 Latency: 350 ns typical
 Accuracy: ±0.5% of reading, ±2 mV offset maximum
 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 (maximum)
External-single channel digital trigger (TTL trigger input):
 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
 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, maximum
