Setting the Trigger Type Configuration
External Trigger via the Computer Interface
Slow
Medium
Fast
[1] Depends on A/D trigger speed.
[2] Depends on how fast the trigger signal is transmitted.
Rate
To set the trigger type configuration using the computer interface, enter the command
TRIGGER <type> (where <type> is the trigger type) and press Enter. See Table 4-3 for
trigger types.
Select trigger type 3 or 5 to enable the settling delay if the input signal is not stable before
a measurement is triggered. Typical settling delays are provided in Table 4-3. RS-232
reading transfer rates are provided in Table 4-4.
To trigger a measurement using the RS-232 computer interface, enter the command
*TRG and press Enter. See the “Common Commands” section later in this chapter for use
of *TRG command.
To trigger a measurement using pin 9 of the RS-232 interface, see
Figure 4-1.
In external trigger mode (mode 2 to mode 5), *TRG command is always
available.
If you enter the remote mode with trigger type 4 or 5 selected, the Meter remains in
its external trigger state; however, because the Meter is in the remote mode, you will
only be able to trigger measurements with rear trigger types 4 and 5. To exit remote
mode, perform steps 1 and 2 and select trigger type 2 or 3 (as applicable).
