1. The external trigger input terminal and trigger gate input terminal are also used as external clock input terminals. (On the
DL1735E/DL1740E/DL1740EL, the terminals are EXT CLOCK IN/EXT TRIG IN/TRIG GATE IN, and on the DL1720E it is
labeled EXT.)
See the specifications of the external clock input (see section 17.3).
2. Under standard operating conditions (see section 17.11) after the warm-up.
3. The input frequency range when using the terminal as a trigger gate input is DC to 50 MHz.
