viPrintf(vi, "*CLS\n");// Clears signal generator status byte
viPrintf(vi, "STAT:OPER:NTR 8\n");// Sets the Operation Status
Group // Negative Transition Filter to indicate a // negative
transition in Bit 3 (Sweeping)
// which will set a corresponding event in // the Operation
Event Register. This occurs // at the end of a sweep.
viPrintf(vi, "STAT:OPER:PTR 0\n");// Sets the Operation Status
Group // Positive Transition Filter so that no
// positive transition on Bit 3 affects the // Operation Event
Register. The positive // transition occurs at the start of a
sweep.
viPrintf(vi, "STAT:OPER:ENAB 8\n");// Enables Operation Status
Event Bit 3 // to report the event to Status Byte // Register
