4 - 60 COMMAND REFERENCE

INITiate:CONTinuous

Syntax: INITiate:CONTinuous <Boolean>

Query form: INITiate:CONTinuous?

Response: 1 0

1Continuous automatic initiation is ON.

0Continuous automatic initiation is OFF.

Description:

The INITiate:CONTinuous command selects whether the trigger system is continuously initiated or not. When INITiate:CONTinuous is ON, the trigger system is continuously initiating acquisitions. This can only be stopped by setting INITiate:CONTinuous to OFF or by sending *RST. The ABORt command stops the current acquisition, but doesn’t affect the setting of INITiate:CONTinuous. Therefore, new acquisitions are initiated immediately.

After a *RST command, INITiate:CONTinuous OFF is valid.

PROGRAMMING NOTES:

•During INITiate:CONTinuous ON the trigger system remains initiated (does not return to the IDLE state). This implies that when an *OPC command is given, bit 0 (OPC) in the standard Event Status Register (ESR) will never be

set. Neither the response to an *OPC? query will be generated, which causes a hang-up of the CombiScope when the response is read.

•After receiving one of the commands INITiate or INITiate:CONTinuous ON, the oscilloscope checks the following *RST trigger settings:

•	X-deflection	OFF
•	Del’d TB	OFF
•	Trigger	Edge
•	Level-PP	OFF
•	X vs Y	OFF
•	Roll mode	OFF
•	Event delay	OFF	digital mode
•	Peak detection	OFF

In case of a settings conflict, the command is ignored and error -221 "Settings conflict" is reported. To avoid this , first send a *RST command before sending an INITiate command.

Example:
Send → *RST	Resets the instrument.
Send → CONFigure:AC (@1)	Configures for AC channel 1.
Send → INITiate:CONTinuous ON	Continuous initiation.
Send → FETCh:AC?	Fetches AC-RMS value.
Read ← <AC-RMS voltage>	Reads AC-RMS voltage.
