Pico Technology PG914 Pulse Generator

Overview

The Pico Technology PG914 is a portable, USB-powered pulse generator combining external tunnel diode pulse heads with integrated step recovery diode SMA outputs. This hybrid configuration provides maximum flexibility for spectral and time-domain transmission and reflectometry measurements across a wide range of applications and frequency bands.

• Pulse frequency: 1 GHz maximum
• Pulse width: 200 ns to 4 microseconds adjustable
• Internal clock: 1 microsecond to 1 second period adjustable
• Tunnel diode transition time: < 40 ps
• SMA output transition time: < 60 ps single-ended
• Tunnel diode output amplitude: Fixed 200 mV
• SMA output amplitude: 2.5 V to 7 V variable
