| 25 With full video bandwidth. Reduce the specified minimum levels according to the reduction of sampling noise at lower bandwidths. |
| 26 Specifications are valid from +15 °C to +50 °C ambient temperature. Below +15 °C, video bandwidth and single-shot bandwidth continuously decrease down to 20 MHz (typical) at 0 °C. Accordingly, the sensor rise time increases up to 50 ns for signals below 500 MHz and up to 20 ns for higher frequencies (typical at 0 °C). |
