Trigger Function
Trigger Input
A trigger input operation example is shown in Figure 2-20 . Measurement or source
output can be started by the input trigger sent through the port specified by the TGP
command. See
Table 2-3 .

Initial Settings The following functions are available in the initial settings:
• Trigger port: Ext Trig In
• Trigger type: Start Measurement (type 1)
• Commands for the trigger wait: WS, TM3, or PA with TM3
Input Trigger
The E5260/E5270 responds to the input trigger (minimum pulse width 10
μ
s) that
changes the signal level from high (approx. 2.4 V) to low (approx. 0.8 V). This is
negative logic. You can change it to positive logic by using the third parameter of
the TGP command.
Measurement
Trigger Delay
Delay time from a trigger input to starting a step measurement. The delay time is
available for the Start Step Measurement trigger (type 3). You can set the delay time
value by using the WT command.
