The USB-61210 conversion clock may originate with the internal hardware timer or externally via CONV (external A/D conversion clock) pin. While the conversion clock source can be chosen by setting AI source configuration, if precision acquisition is required, use of the internal hardware timer is recommended.

Page 37: Trigger Modes
An external digital trigger occurs when a rising or falling edge is detected on the digital signal connected to the AITG (analog input trigger) pin. Trigger polarity can be programmed using JYTEK software drivers. Signal level of the external digital trigger signals should be LVTTL-compatible, with a minimum pulse of 20ns. -
Page 38: Figure 3-9: Delayed Trigger
Delayed-Trigger Acquisition Mode (no retriggering) Delay-trigger acquisition is indicated when the data collection is to be delayed following the trigger event, as shown. Delay duration is speci- fied by a 32-bit counter value, whereby maximum delay is the period of TIMEBASE X (2 - 1), and minimum delay the period of the timebase. -
Page 39: Figure 3-11: Pre-Trigger
An example is shown, in which N samples of data are acquired after the first trigger signal, after which the USB-61210 awaits the next re-trigger signal (re-trigger signals occurring before the N samples are completed will be ignored). -

cation. After software start, the counter calculates the number of active edges on GPTC_CLK when GPTC_GATE is in its active state. After the completion of the pulse-width interval on GPTC_GATE, GPTC_OUT outputs high and current count value can be read by the software application. -
Page 45: Figure 3-18: Mode 5-Single-Triggered Pulse
Mode 5: Single-Triggered Pulse This mode generates a single pulse with programmable delay and pro- grammable pulse-width following an active GPTC_GATE edge. These programmable parameters can be specified in terms of periods of the GPTC_CLK input. When the first GPTC_GATE edge triggers the single pulse, GPTC_GATE has no effect until software start is executed again. -

Mode 7: Single-Triggered Continuous Pulse Generation This mode is similar to Mode 5 except that the counter generates con- tinuous periodic pulses with programmable pulse interval and pulse-width following the first active edge of GPTC_GATE. When the first GPTC_GATE edge triggers the counter, GPTC_GATE has no effect until software start is executed again. -
