PCM-3780 User Manual 52 D.7 Mode F W aveforms Non-Retriggera ble One-Shot Mode F provides a non-retriggerabl e, one-shot, timing function . The counter must be arm ed before it will fun ction. Applicati on of a gate edge to the armed counter will enable c ounting.
53 Appendix D D.8 Mode G W aveforms Software-T riggered De layed Pulse One-Shot In Mode G , the gate does no t affect the counter's operation. Once armed, the counter will count to TC twice and then autom atically disarm itself.
PCM-3780 User Manual 54 D.9 Mode H W aveforms Software-T riggered Delayed Pulse One-Shot with Hardwar e Gating Mode H is identical to Mode G except that the gate inpu t is used to qual- ify which source edges are to be count ed. The counter must be armed for counting to occur .
55 Appendix D D.10 Mode I W aveforms Hardware-T riggered Delayed Pulse S trobe Mode I is identical to Mo de G , excep t that counting will not begin unti l a gate edge is applied to an armed coun ter . The counter must be armed before application of the trigg ering gate edge.
PCM-3780 User Manual 56 D.1 1 Mode J W aveforms V ariable Duty Cycle Rate Generator with No Hardware Gat ing Mode J will find the greatest usage in frequency generatio n applications with variab le duty cy cle requirements. Once ar med, the count er will count continuousl y until it is issued a DISARM command.
57 Appendix D D.12 Mode K W a veforms V ariable Duty Cycle Rate Generator with Level Gating Mode K is identical to Mode J except that source edges are only counted when the Gate is active.
PCM-3780 User Manual 58 D.13 Mode L W aveforms Hardware-T riggered Delayed Pulse One-Shot Mode L is similar to Mode J except that counting will not begin before a gate edge is applied to an armed coun ter . The counter must be armed before application of th e triggering gate edge; g ate edges applied to a dis- armed counter are disregarded.
59 Appendix D D.14 Mode O W aveforms Hardware-T riggered S trobe with Edge Disarm Mode O, shown in Figure O, is identical to Mode C except that the counter will be disarmed while an in active-going gate edge is applied to the counter . And the counter will hold the count value until it is issued a LOAD command or REST command.
PCM-3780 User Manual 60 D.15 Mode R W a veforms Non-Retriggerbale One-Sh ot with Edge Disarm Mode R is identical to Mode F except that the counter will be disarmed while an inactive-going ga te edge is applied to the counter . The counter will hold the count value until it is issued a LOAD command or REST command.
61 Appendix D D.16 Mode U W a veforms Hardware-T riggered Delayed Pu lse S trobe with Edge Disarm Mode U is identical to Mode I except that the counter will be disarmed while the gate and inactive-going gate edge is applied to the counter . The counter will hold the count value unt il it is issued a LOAD command or REST command.
PCM-3780 User Manual 62 D.17 Mode X W a veforms Hardware-T riggered Delayed Puls e One-Shot with Edge Disarm Mode X is identical to Mode L excep t that the counter will be disarmed while an inactive-going ga te edge is applied to the counter .
