State of Sequence

The three states (IDLE state, INITiated state, and WTG tate) are available in the sequence operation.

IDLE state

When the PCR-M/ PCR-LE/PCR-LE2 is turned on, all the trigger subsystems are in the IDLE state. In this state, the trigger subsystems ignore all triggers. Sending one of the following commands at any time also returns the trigger subsystems to the IDLE state.

The sequence does not start in the IDLE state, even when TRG is sent.

:ABORt (":INIT:CONT OFF;:ABOR" on the PCR-M if the auto continue mode is turned on)

*RST

*RCL

IEEE488.1 sdc(Selected Device Clear) or dcl(Device Clear)

INITiated state

If INIT is sent in the IDLE state, the trigger function starts and the PCR-M/ PCR-LE/PCR-LE2 enters the INITiated state.

If the trigger source is set to IMMediate, the settings are changed immediately, or the measurement, power line abnormality simulation, or sequence starts immediately.

If the trigger source is set to BUS, the PCR-M/ PCR-LE/PCR-LE2 enters the WTG (Waiting for Trigger) state.

WTG (Waiting for Trigger) state

If a trigger is received in the WTG state, the settings are changed, or the measurement, power line abnormality simulation, or sequence starts.

Auto continue mode (TRANSIENT and ACQUIRE of PCR-M only)

If auto continue mode is turned on, measured data is automatically refreshed without having to send the INIT command each time. In normal cases, turn auto continue mode off (default).

If you are using the PCR-M series with firmware version 1.19 or earlier, see here.

When the sequence operation auto continue mode is turned on

When the trigger source is set to IMMediate, the settings are changed immediately, or the measurement, power line abnormality simulation, or sequence starts immediately. When the operation completes, the new change is made automatically, or the measurement, power line abnormality simulation, or sequence starts automatically. However, if auto continue mode is on, the MEASure, READ, and FETCh queries operate in the same manner. This means that sending multiple FETCh queries results in different measurement results, and simultaneity is lost.

When the trigger source is set to BUS, the PCR waits for a software trigger before making the change or starting the measurement, power line abnormality simulation, or sequence. When the operation has completed, the PCR waits for the next trigger.

The ABORt command to the measurement function is invalid, because the trigger subsystem automatically exits the IDLE state even if aborted. The *RST/*RCL command resets the continuous operation to off.

When the sequence operation auto continue mode is turned off

The change or measurement currently in progress continues unless ABOR is sent. The operation does not automatically continue to the new change or measurement.
