Model 2750 Multimeter/Switch System User’s Manual Common Commands 12-7
The Model 2750 has three overlapped commands:
:INITiate
:INITiate:CONTinuous ON
• *TRG
NOTE See *OPC, *OPC?, and *TRG for more information.
The INITiate commands remove the Model 2750 from the idle state. The device opera-
tions of :INITiate are not considered complete until the Model 2750 returns to idle. By
sending the *WAI command after the INITiate command, all subsequent commands will
not execute until the Model 2750 goes back into idle.
The *TRG command issues a bus trigger that could be used to provide the arm, scan, and
measure events for the Trigger Model. By sending the *WAI command after the *TRG
command, subsequent commands will not executed until the pointer for the Trigger Model
has finished moving in response to *TRG and has settled at its next state.
Programming example – The following command sequence shows how to use the WAI
command to allow the 2750 to wait for the programmed measurements to be completed
before requesting a reading.
SYST:PRES ‘ Returns 2750 to default setup.
INIT:CONT OFF ‘ Disables continuous initiation.
ABORt ‘ Aborts operation. Places 2750 in idle.
TRIG:COUN 1 ‘ These two commands configure the 2750
SAMP:COUN 30 ‘ to perform 30 measurements.
INIT ‘ Starts measurement process.
*WAI ‘ Sends the WAI command. Program waits for
‘ 2750 to go into idle before executing next
‘ command.
DATA? ‘ Requests one reading.
