Digital Pulse Amplifier DIV 20
Digital pulse amplifier for all LM0202 and LM13 laser modulators with half wave voltage up to 590 V
Generates rectangular voltage pulses of variable pulse length and adjustable amplitude
Control via 5 V TTL signal
Specifications:
Signal voltage1)2): 30-590 V
Rise-/fall time (10-90 %) 3): < 28 ns, ( typ. 20-25 ns at 350 V, typ. 23-27 ns at 590 V)
Repetition rate4): 1 to 20 MHz
Offset-voltage1) 2): 0-590 V
External control via Sub-D25p-female-port
Line voltage: 90-264 V
Line frequency: 47-63 Hz
1) Relative to ground
2)This voltage can be set manually or externally by a control voltage from 0 to +10 V (input impedance 5 kΩ) with a speed of <100 ms from 70 V to 480 V (rise) or from 480 V to 70 V (fall) respectively
3)The optical rise-/fall time is achieved with a modulator LM 0202, connected via the standard connection cable (L = 80 cm)
4)Typical maximum signal voltage at repetition rate 5 MHz 300 V, at 3 MHz 400 V and at 1 MHz 590 V
