INITiate
The
INITiate
command subsystem places the multimeter in the wait-for-trigger state.
This command is most commonly used with
CONFigure
.
Subsystem Syntax
INITiate
[:IMMediate]
[:IMMediate]
INITiate[:IMMediate]
places the multimeter in the wait-for-trigger state. When a
trigger is received, readings are placed in mainframe/command module memory.
Comments
•
After the trigger system is initiated using
INITiate
, use the
TRIGger
command
subsystem to control the behavior of the trigger system.
•
If
TRIGger:SOURce
is
IMMediate
, the measurement starts and readings are stored
in mainframe/command module memory as soon as
INITiate
is executed.
Readings stored in memory from previous commands are replaced by the new
readings.
•
To transfer readings from memory to the output buffer, use the
FETCh?
command.
•
If the multimeter is in the wait-for-trigger state, the
ABORt
command places the
multimeter in its idle state and terminates any measurement in progress.
•
Each multimeter module is allocated enough mainframe memory to store 100
readings. Each reading stored is four bytes long. Since readings are stored in a
four-byte format,
INITiate
is faster than sending readings directly to the output buffer
using the
READ?
command. If more than 100 readings are requested, and memory is
available, the mainframe allocates additional memory to the multimeter.
•
The
READ?
command executes
INITiate
implicitly. The
MEASure
command
executes
READ?
implicitly.

Example
Placing Multimeter in Wait-For-Trigger State
CONF:VOLT:DC (@100:104)
!Function: DC voltage; specify channel list.
TRIG:SOUR EXT
!Trigger source is external BNC on
multimeter front panel.
INIT
!Place multimeter in wait-for-trigger state;
store readings in memory when trigger is
received.
FETC?
!Place readings in output buffer.
INIT
!You must reinitiate the wait-for-trigger
state after each trigger cycle.
