For DL1540/DL1540L External clock can be selected from the following two signals.
• Input signal to “EXT CLOCK IN”
Connector type : BNC
Maximum input voltage : ±6 V
Input frequency range : 40 Hz to 15 MHz (only for continuous clock)
Input level : TTL/CMOS level recommended (0.3 Vp-p or greater at the end of
the connector, ±0.15 V or greater relative to the threshold level)
Input impedance : Approx. 1 MΩ
Threshold level : 1.5 V or 0.15 V
Minimum pulse width : 25 ns or more for both High and Low levels
• Input signal to CH4
Input frequency range : 40 Hz to 40 MHz (only for continuous clock)
Input level : 2 divp-p or higher
Threshold level : Set by the trigger level (CH4)
Minimum pulse width : 5 ns or more for both High and Low levels
* Measured after 30-minute warm-up, under the standard operating conditions stipulated on page 16-8.
