The Problem
LiDAR scenario emulation and pulsed-laser-diode test demand long, precisely-timed waveforms across multiple channels. Memory depth and trigger jitter usually become the limiting factors. Most arbitrary waveform generators (AWGs) run out of memory at 1 to 2 Gpts and accumulate jitter once channels are stacked.
Why the BNC 686 Fits LiDAR Test
A single AWG family that holds long scenarios in memory and keeps jitter and channel skew within instrument tolerances. Direct drive at usable amplitude removes the need for an external amplifier in most fixtures.
- Up to 9 Gpts of waveform memory per channel for long scenarios
- Sub-2 ps trigger jitter against an external master clock
- Sub-100 fs channel synchronization across separate units
- 50 ps timing resolution for emulated reflected pulses
- 5 Vpp into 50 Ω supports direct drive of pulsed laser diode test fixtures (or the BNC high-voltage pulse generator sibling for 50 V / 1 A square pulses)
Requirements vs. BNC 686 Capability
| LiDAR Test Requirement | BNC 686 Capability |
|---|---|
| Long-scenario waveform memory | Up to 9 Gpts per channel |
| Trigger jitter against external master clock | < 2 ps |
| Channel synchronization across separate units | < 100 fs |
| Timing resolution for emulated reflected pulses | 50 ps |
| Direct-drive amplitude into 50 Ω | 5 Vpp |
| High-current diode drive (sibling instrument) | BNC HV pulse generator: 50 V / 1 A square pulses |
Where This Is Running
OEM Sensor labs, defense electro-optical and infrared test groups, as well as LiDAR maker hardware teams, are currently interested in Berkeley Nucleonics arbitrary waveform generators for running long-scenario emulation across multiple channels.
