[Tester] Operations using EXT TRIG on INS-4020/4040 include EXTERNAL TRIG mode operation (Instruction Manual p.36) and remote operation (same manual p.51). Is there any difference between the two?

EXTERNAL TRIG mode operation (p.36): When operating by turning the EXT TRG button ON after power startup, start/stop operation is enabled.
During test start, when a Low level is detected from the external synchronization signal input connector (BNC), only one pulse is output.

Remote operation (p.51): When the power is turned on while the EXT TRG button is pressed, pulses continue to be output while a Low-level input is being applied from the external synchronization signal input connector (BNC), regardless of start/stop operation.
