| Bandwidth | 50 MHz min |
| Threshold voltage | 1.2V - 2.3V |
| Data buffer Size | 1 Meg samples per channel |
| Pre/post-trigger buffer | Data buffer is divided in pre- and post trigger section, sizes can be set in 1000 samples steps |
| Internal sampling clock | |
| Rates | 500MHz, 200MHz, 100MHz, 50MHz, 25 MHz, 10MHz, 5MHz, 2.5MHz, 1MHz, 500kHz, 250 kHz, 100kHz, 50kHz, 25 kHz, 10kHz, 5kHz, 2.5kHz |
| Stability | 100 ppm |
| External sampling clock | Input to Ch7 |
| asynchronous | clock on rising/falling edge, 25 MHz max. |
| synchronous | clock on rising/falling edge, 10 MHz max. |
| data valid 30 ns before and after clock edge on Ch7 | |
| Digital logger clock | |
| Rates | Log rate: 1 second to 1 hour in 1 second steps |
| Stability | Logger timing obtained from PC |
| Post Trigger Delay | Depending on sampling frequency; 500MHz: maximum delay = 131 us 200MHz: maximum delay = 10 ms 1MHz: maximum delay = 16 sec 2.5kHz: maximum delay = 6710 sec Accuracy: 5 x sampling period. |
| Trigger conditions | |
| Pattern | "1", "0" and "don't care" conditions selectable on all channels |
| Edge | On any channel. Rising edge, falling edge, or change-of-state |
| Edge/Pattern combinations | edge up, edge down, edge up OR edge down (change-of-state) pattern pattern OR edge up/edge down/change-of-state pattern AND edge up/edge down/change-of-state pattern THEN edge up/edge down/change-of-state edge up/edge down/change-of-state THEN pattern pattern < duration (glitch capture). Duration ±20ns tolerance, 1 ms max. pattern > duration. Duration ±20ns tolerance, 1 ms max. |
| Continuous | Unconditionally: Screen updates at regular intervals Conditionally: Display updates on set Edge/Word trigger condition |
| Mouse/Keyboard | A trigger may be forced |
