1 The external trigger input terminal (EXT TRIG IN)/trigger gate input terminal (TRIG GATE IN) is also used as an external
clock input terminal (EXT CLOCK IN). See the specifications of the external clock input (see section 17.4).
2 Under standard operating conditions (see section 17.12) after the warm-up.
3 The input frequency range when using the terminal as a trigger gate input is DC to 50 MHz.
