Floating Architecture

- PC-performance independent: multiple SPEA CPUs
  provide test program timing, while pc replacement does
  not require the test program requalification
- Multi-Core Architecture: possibility to develop and run 2 independent test programs simultaneously, in asynchronous way
- Pattern-based programming: -30% test time vs
- 64-line synchrobus and 16-line high-speed synchrobus for
  real-time instrument synchronization: no embedded delay
  when running pattern-based testing
- 99% parallel test efficiency
- Multi-site test capabilities for up to 256 devices in parallel
- High-density, floating instruments, for true parallel analog
- Universal slot architecture, up to 1,408 channels
- RF generators up to 3 GHz











Analog Pin Performance

- 1 SPEA board takes the place of 4 competitor boards
- Totally floating, independent for sensing/forcing per channel
- Wide V/I range: ±100V / ±1A, ±20V / ±2A, ±20V / 500mA
- 32 DVM digitizers into Readback, totally independent
  and independently floating
- 8 DVMs available on interface to measure on different
  points from the sourcing ones
- Clamp alarms, spike detector, automatic ramp generators
- Arbitrary Waveform Generators and Time Measurement
  Units per channel











Digital Pin Performance

- Test time for timing measurement is 1/8 than competitors
  for digital data calculation and protocol management
- 200 MHz frequency
- 16 M Pattern memory
- Voltage range -2 to +6.5V or -2 to 14V
- Active load integrated in the digital pin
- Integrated DPS (-2 to +24V, ±500mA)
- 8 integrated Timing Measurement Units (with possibility
  of multiple time measurements on the same channel)
- Integrated Programmable Logic Units











Signal Processing Instruments

- Octal Digitizer & DSP for real time data acquisition
  & processing: 16 bit HF, 24 bit Audio BW
- Quad AC generators: 14 bit HF, 20 bit Audio BW
