5.2.10.1 Restrictions on Using External Trigger
This section describes restrictions on using the external trigger (TRIGGER IN signal).
As in slave CH in the synchronized operation, TRIGGER IN signal controls the timing of source and mea-
surement to synchronize with the external devices.
Confirm the following restrictions before inputting the external trigger to prevent malfunctions of source
and the measurement.
Restrictions:
1. Do not input the TRIGGER IN signal in Standby status or when switching between Operate, Suspend,
and Standby.
2. Ensure that the TRIGGER IN signal, the trigger from the TRG key, and Remote trigger (*TRG) do
not overlap.
3. Restrictions on Pulse period setting value Tp and Hold time setting value Th
When using the external trigger (TRIGGER IN signal) setting, pulse period Tp and Hold time Th are
restricted (see Table 5-13 and Table 5-14).
4. Restrictions on the time Thp (ext) from Sweep-start to the next Trigger signal input
Setting the time Thp (ext) from inputting Sweep-start trigger-signal to inputting the next step trigger
signal is restricted for the sweep source (see Table 5-13 and Table 5-14).
5. Restrictions on the required time Top from specifying Operate to inputting the external trigger
Minimum time is required for the time Top from specifying Operate by a remote command or an
external signal (OPR In signal) to inputting the external Trigger (See Table 5-15).
6. Allow the 6241A/6242 at least 10 ms after completion of the previous Sweep to input sweep-start
TRIGGER-IN signal.
