ToPer - To Period

Except when in External Trigger or Single Shot mode, all pulse outputs are based on an inter- nal timer called To. This menu is used to select the rate at which To runs by selecting the time period in microseconds between timer pulses. When in Continuous, Burst, or Duty Cycle mode, pulses are output at the rate determined by To. The frequency of pulse outputs in these modes can be found by taking the reciprocal of the To Period setting.

Width and Delay Menus

This set of menus is used to set the delay and pulse width for each of the output channels.

Note: Channel 2 delay is relative to the Channel 1 (T1) output.

Tn:Dly - Tn Delay

Each of the two channels has an independent delay setting which is set from the Tn:Dly, where n = 1 or 2.

When in any mode but External Trigger, the Delay setting sets the delay from the time the in- ternal timer To goes high until a pulse is output on a particular channel.

Note: In the case of Channel 2 (T2), the output is delayed from the active edge of T1 - not To as with the other channels.

When in External Trigger mode, the delays are with respect to the active edge of the external trigger input signal.

Tn:Wid - Tn Pulse Width

Each of the two channels has an independent pulse width setting which is set from the Tn:Wid menu, where n = 1 or 2.

The pulse width is used to specify the duration of the output pulse in μS. The setting of the output polarity (the Tn:Pol menu) for a particular channel determines whether the output is high for this duration or is low.

Tn:Pol - Tn Polarity

Each channel has an independent output polarity setting set from the Tn:Pol menu, where n = 1 or 2.
