INITiate

Syntax

INITiate

Description This command changes the state of the triggering system from the "idle" state to the

"wait-for-trigger" state. Scan will begin when the specified trigger conditions are satisfied.

Readings acquired during the scan are stored in the internal reading memory of the

instrument. Note that the INITiate command also clears the previous scan readings from

the memory.

If the scan list was defined (refer to the ROUTe:SCAN command ) already,

the INITiate command will scan the specified channel in the scan list. If the scan list was

not defined, an error will be generated when sending the INITiate command.

Explanation  Storing the readings into the memory using the INITiate command is generally faster

than sending the readings to the memory using the

READ? command. The INITiate

command is also an "overlapped" command, namely after sending the INITiate

command, you can send other commands that do not affect the measurements.

 When scanning the multiplexer channels, an error is generated if the DMM module is

disabled (refer to the

INSTrument:DMM command) or not installed in the mainframe

and the advanced source mode is disabled. The DMM module is not required when

scanning the multifunction module channels.

 When the scan is initiated, the instrument will open all the channels of the module of

the multiplexer channel in the scan list.

 The instrument scans the list of channels in ascending order from Slot1 through slot

5. The instrument stores the channel numbers in ascending order even when you

have already defined the order of the channels in the scan list. For Example, when

the channel numbers in the scan list are defined as (@109:101), the instrument

stores the channel numbers in 101, 102, 103… order.

 Once the trigger status of the instrument changes from “Idle” to “Wait-for –trigger”,

an error will be generated if you attempt to change any measurement parameters

(send the

CONFigure Command Subsystem and SENSe Command Subsystem

commands) or the triggering configuration (send the

TRIGger Command Subsystem

commands). To abort a scan in progress, send the ABORt command.
