TA TRIGGER ACQUISITION
Purpose: The command will simulate a trigger, meaning it will initiate an acquisition
(assuming the ScopeMeter was ready to be started).
This command acts as a hardware trigger that starts a new acquisition.
In SINGLE shot acquisition mode the trigger system must have been armed with the
AT (Arm Trigger) command before the TA command can be used.
Command Syntax:
TA<cr>
Response Syntax:
<ackn><cr>
Example: See example below
‘***************** Beginning of example program *****************
CLS ‘Clears the PC screen.
OPEN “COM1:1200,N,8,1,CS,DS,RB2048” FOR RANDOM AS #1
PRINT #1, “TA” ‘Sends TRIGGER ACQUISITION command.
GOSUB Acknowledge ‘Input acknowledge from ScopeMeter.
END
‘******************* Acknowledge subroutine *********************
‘Use this subroutine after each command or query sent to the
‘ScopeMeter. This routine inputs the acknowledge response from
‘the ScopeMeter. If the response is non-zero, the previous
‘command was not correct or was not correctly received by
‘the ScopeMeter. Then an error message is displayed and
‘the program is aborted.
Acknowledge:
INPUT #1, ACK ‘Reads acknowledge from ScopeMeter.
IF ACK <> 0 THEN
PRINT “Error “; ACK; “: “;
SELECT CASE ACK
CASE 1
PRINT “Syntax Error”
CASE 2
PRINT “Execution Error”
CASE 3
PRINT “Synchronization Error”
CASE 4
PRINT “Communication Error”
CASE IS < 1
PRINT “Unknown Acknowledge”
CASE IS > 4
PRINT “Unknown Acknowledge”
END SELECT
PRINT “Program aborted.”
