Pattern Generator boards solutions include:
Pattern Generator boards carry:
Output XY DACs and input ADC voltages can be tuned for arbitrary intervals in ±12.0 V range. Time characteristics of the Pattern Generators depend on Exposure / Image Acquisition modes: |
| Time characteristics | Elli-28 | Elli-27 | |
| |
Minimal exposure dwell time (period of XY DACs addressing) | 0.2 us | 0.4 us |
| |
Minimal Image Acquisition time (period of XY DACs addressing + getting ADC signal) | 2.0 us | 3.5 us |
| |
Dwell time step (accuracy of dwell time increasing) due to empty loop of PC depends on processor frequency. For example, if processor frequency is 1000 MHz then dwell time step is near | 2 ns | 2 ns |
| |
Minimal exposure dwell time in BeamOutAfterPoint mode (time between BlankOff - BlankOn addressing) | 0.4 us | 0.4 us |
| |
On-Board Image Accumulation (per Accumulation cycle) | 0.12 us | - |
