Note: The measurements should be made by crossing a 10uF electrolytic
and a 0.1uF ceramic disk capacitor at each output measuring band-
width from DC to 20MHz. If ambient temperature is under 20 or
over 30, the AC input should be nominal input.
4.6. Remote ON/OFF Control
The power supply outputs shall be enabled with an active-low TTL signal.
When TTL signal is low, the DC outputs are to be enabled. When TTL
signal is high or open circuited, the DC outputs are to be disabled. Electronic
means or a mechanical switch may activate the TTL signal. After the TTL
signal is active high, must wait for 3 seconds before active low again.
