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-voltage^{1) 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
