The Elli29 PCI is a perfected model of our previous pattern generators. As
its predecessors,
Elli29 is an advanced data acquisition product with high speed Digital-to-Analog
addressing capabilities and Analog-to-Digital sample conversion in conjunction
with improved noise-immunity.
Pattern Generator solutions include:
Digital board for PCI bus slot inside the PC
Analog desktop unit with its own stabilized power supply
2 meter fiber optic cable
Set of signal cables
Power cord
Software Drivers
Analog unit is connected to Digital board by fiber optic cable to perform galvanic
decoupling from PC and to provide high speed noise protective data transfer.
Pattern Generator boards carry:
Two 16-bit Digital-to- Analog Converters (DACs) (60ns Settling Time)
Output XY DACs and input ADC voltages can be tuned for arbitrary intervals
in ±10.0 V range.
Time characteristics of the Pattern Generator depend on Exposure / Image
Acquisition modes:
Minimal exposure dwell time (period of XY DACs addressing)
0.15
us
Minimal Image Acquisition time (period of XY DACs addressing + getting
ADC signal)
1.0 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
Minimal exposure dwell time in BeamOutAfterPoint mode (time between BlankOff
- BlankOn addressing)
