Acquisition Functions 131GENERAL TAB (OUTPUT PREFERENCES)General TabNumber of PulsesInitiate pulse sequencewith…ON/OFF ButtonOFF (red)ON (green)AUTOMATIC START(yellow)RecordingStart buttonIndicates the number of pulses to be output. When the Output Control panel is closed, thepulse output will be immediately stopped.Single will establish a single pulse for outputting. All pulse repetition options, entry boxesand scroll bars in both the control panel and preferences windows will be disabled(grayed).Multiple will establish a specific number of pulses for outputting. The selection willactivate an entry box where you can enter 1-254 pulses. When this option is selected, thePulse Repetition scroll bar is activated in the Output Control panel.Continuous will establish a continuous pulse train for outputting. When this optionis selected, the Pulse Repetition scroll bar is activated in the Output Control panel.MP30 Only If using High Speed mode (>2,000 s/s) and “Initiate pulsesequence with Recording” is selected, the stimulator cannot be turned off manuallysince the MP30 will not accept any commands from the computer until therecording has stopped.If “Initiate pulse sequence with ON/OFF button in Output control panel” isset, the pulse sequence will be stopped prior to acquisition and will have to bemanually turned back on after the recording.Controls the start and stop of pulses. Changes to Pulse Width and Repetition Rate can bemade in the Output Control panel entry boxes during a pulse sequence, and during arecording, if all other Preferences parameters allow it. Any change in the pulse output willoccur immediately. This lets you change the stimulator output “on the fly.”When “Initiate pulse sequence with ON/OFF button” is selected:The ON/OFF button controls pulse output independent of the acquisition status.OFF is always available.The ON/OFF button reflects the current output state, with one exception: if the pulsesequence lasts less than 0.5 seconds, the button will remain in the “ON” state for atleast 0.5 seconds to indicate that the ON state occurred.When the Number of Pulses selected is Multiple, ON/OFF acts as a momentary switch.Press the ON (green) button to start pulses;it will automatically turn OFF (red) at the end of the specified pulse train.The switch defaults to OFF. Saving a data file or saving as a Graph Template will save allstimulator preferences except the status of the pulse switch, which will always be saved inthe OFF position.When “Initiate pulse sequence with Recording” is selected:If the preference setting “Initiate pulse sequence with: ON/OFF button” is active,the control panel changes will take effect immediately. If settings are changedduring a pulse train, changes do not take effect until the next time the stimulator
