| Fig. 1. Elli30 PCIe Pattern Generator |
Elli30 PCIe is an advanced model of our previous pattern generators, designed
to improve performance of core operations. As its predecessors, Elli30 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.
The new solutions include:
- Digital board for PCIe bus slot inside the PC, to provide high productivity
and better compatibility with modern and future PC
- Two 2 GHz optical channels between Digital and Analogue modules to
improve the speed of data transfer and, accordingly, two fiber-optic cables
- Control of dwell time using a timer inside the pattern generator
Pattern Generator consists of:
- Analogue desktop unit with its own stabilized power supply
- Digital board for PCIe bus slot inside the PC
- Two fiber optic cables (2 meter, can be enlarged up to several
tens of meters)
- Set of interface cables
- Power cord
- Software drivers for 32-bit Windows OS 9х/NT/2000/XP/7/10
Digital board carries:
- Two 16-bit Digital-to- Analog Converters (50 MHz DACs)
- One 8-bit Analog-to- Digital Converter (ADC)
- Beam Blanker On/Off switch (TTL output level)
- Internal/External scan mode switch (TTL output level)
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 |
50 ns (20 MHz) |
| |
Dwell time resolution |
10 ns (100 MHz) |
| |
On-board image accumulation (per accumulation cycle) |
50 ns (20 MHz) |
| |
Minimal image acquisition time (time of XY DACs addressing + transferring
of ADC signal) |
0.8 us
(implying 12 accumulation cycles)
