6. The

Mode

field defines how the trigger activates a sequence. Each mode are not compatible with each combi-

nation of trigger type and repeatability. Figure

2.8

shows the different available combinations for the different

Trigger Modes. Four Modes are available and are the following:

Uninterrupted

: This mode activates the channel sequence when an input greater than 3.3 V is detected

by the BNC input. Following input pulses will be ignored while the sequence is running (Fig.

2.4

). When

the

Repeatable sequence

checkbox is checked, the sequence will restart with the arrival of the first input

pulse after the sequence has finished (Fig.

2.4b

). This mode is available for

Triggered

pulse only.

Pause

: This mode activates the channel sequence when a rising edge greater than 3.3 V is detected on

the BNC input (Fig.

). Following input pulses (when

will pause the sequence and the sequence will continue when the next rising edge is received.

When the

Repeatable sequence

checkbox is checked, the sequence will restart with the arrival of the first

input pulse after the sequence has finished (Figs.

: This mode activates the channel sequence when a rising edge greater than 3.3 V is detected on

the BNC input (Fig.

reception of the following rising edge. Triggers only affect the output voltage value. When the
