4 - 60 COMMAND REFERENCE
INITiate:CONTinuous
Syntax:
INITiate:CONTinuous <Boolean>
Query form:
INITiate:CONTinuous?
Response:
1 | 0
1 Continuous automatic initiation is ON.
0 Continuous 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.
