Pulse (source only)
Rate : 1 Hz to 10KHz
Input voltage amplitude range on frequency is 1 to 20 V, Trigger level 0.2 to 10 volt. Minimum pulse width 10
µS.
Output amplitude is adjustable from 1 to 20 V and is a square wave with a 50% duty cycle.
For output frequency, a slight negative offset of approximately -0.1 V is present to assure zero crossing.
