Overview of Remote Control
Trigger System
The following two sample programs show the difference between the :TRIG
command and the *TRG commands.
10 ASSIGN @Adrs TO 717
20 REMOTE @Adrs
30 OUTPUT @Adrs;"*RST;*CLS"
40 OUTPUT @Adrs;":TRIG:SOUR BUS"
50 OUTPUT @Adrs;":ABOR;:INIT"
60 OUTPUT @Adrs;":TRIG"
70 OUTPUT @Adrs;":FETC?"
80 ENTER @Adrs;A,B,C
90 END

80 END
Measurement State
In the "Measurement" state, the instrument waits for the sweep delay time to
elapse when it is specified and then starts a measurement cycle (sweep).
When the instrument finishes measurement, the trigger system behaves in one
of the following ways depending on the setting of the continuous initiation
mode.
If the continuous initiation mode is off:
If the continuous initiation mode is on:
When the E4980A/AL is in remote mode, measurements can be made only
on the screen displayed by pressing [Display Format].
A typical flowchart of data transfer using the trigger system is shown below.

In the "Waiting for Trigger" state, the E4980A/AL is triggered by sending
the *TRG command or the TRIGGER (GET) bus command, and
measurement results in one trigger sequence can be read without sending
the :FETCh? query command in the "Idle" state.
Therefore,
"*TRG" = ":TRIG;:FETCh?"
The trigger system switches to the "Idle" state
The trigger system switches to the "Idle" state and then
automatically switches to the "Waiting for Trigger" state
