Rhs2116 Trigger Data

The following excerpt from the HeadstageRhs2116 example workflow demonstrates how to save data about the Rhs2116 stimulus.

The Rhs2116TriggerData operator generates a sequence of Rhs2116TriggerDataFrames. Its DeviceName property is set to "HeadstageRhs2116/StimulusTrigger" which links Rhs2116TriggerData to the stimulus devices on the RHS2116 Headstage.

The CsvWriter operator selects Clock, Delay, Status, and Origin members from the Rhs2116TriggerDataFrame to write to a file with a name of the following format: rhs2116trigger_<filecount>.csv. These members are selected using the CsvWriter's Selector property. They contain the following information:

• Clock: the AcquisitionClockHz-based sample times that a stimulus trigger is received
• Delay: the delay between receiving the trigger to the physical application of the stimulus, in microseconds, as defined by the input to Rhs2116StimulusTrigger
• Status: the delivery status of the stimulus. This includes whether the stimulus was delivered or why it might not have been delivered (i.e. if stimulator is disarmed or the stimulus sequencer is already in the midst of delivering a stimulus).
• Origin: specifies whether the stimulus was triggered by writing to a register, setting a local GPIO pin, or via an external synchronization source
