|---|---|---|---|---|
| PicoScope 9402-05 | 5 GHz | 2 | 1 TS/s | 70 ps |
| PicoScope 9404-05 | 5 GHz | 4 | 1 TS/s | 70 ps |
| PicoScope 9402-16 | 16 GHz | 2 | 2.5 TS/s | 22 ps |
| PicoScope 9404-16 | 16 GHz | 4 | 2.5 TS/s | 22 ps |
Key Features
SXRTO Architecture
Combines real-time sampling with random equivalent-time reconstruction for repetitive high-speed signals.
5 GHz and 16 GHz Models
Choose 5 GHz models for lower-cost high-speed timing, or 16 GHz models for faster serial and pulse work.
12-bit 500 MS/s ADCs
Maintains 12-bit acquisition architecture while using equivalent-time sampling to view fast repetitive signals.
2 or 4 Channels
Two-channel and four-channel models support differential pairs, multi-lane timing and multi-point system validation.
Eye and Mask Testing
Useful for serial-data transmitter checks, pulse analysis and waveform quality evaluation.
Compact PC-connected Format
USB-connected instrument keeps the measurement hardware close to the DUT while using a large PC display.
