State of sequence
The following three states are available in the sequence operation.
IDLE state
When the KPM1000 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 (When :INIT:CONT is ON, send :INIT:CONT:SEQ1 OFF;:ABOR.)
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 KPM1000 enters the INITiated state.
If the trigger source is set to IMMediate, measurement is started immediately.
If the trigger source is set to BUS, the KPM1000 enters the WTG (Waiting for Trigger) state.
WTG (Waiting for Trigger) state
If a trigger is sent when the KPM1000 is in the WTG state, measurement starts.
Auto continue mode
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).
When the sequence operation auto continue mode is turned on
If the trigger source parameter is set to IMM, the measurement starts immediately. When the operation is complete, a new measurement automatically starts. 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.
If the parameter is set to BUS, the measurement starts after the KPM1000 receives a software trigger. When the operation is complete, the KPM1000 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.
When the sequence operation auto continue mode is turned off
The measurement currently in progress continues unless ABOR is sent. The operation does not automatically continue to the new measurement.
