External KX Project tracker

  • 3458A footprint, 2U 19" rackmount chassis with front-panel. Aluminum or steel frame, aluminum front panel.
  • Noritake 256x64 dot-matrix graphics VFD
  • LTZ1000A isothermal voltage reference (maybe two), target - 1ppm/year max
  • Integrating multislope ADC in CPLD + LTC2442 ADC for residual charge measurement.
  • 8 1/2 resolution (will see about accuracy)
  • LTC2756 DAC
  • Front and rear therminals (6 wire)
  • DC Voltage measurement: 2mV, 20mV, 200mV, 2V, 20V, 200VDC ranges.
  • DC Voltage source: 2mV, 20mV, 200mV, 2V, 20V ranges.
  • DC Current measurement: 20uA, 200uA, 2mA, 20mA, 200mA.
  • DC Current source: 20uA, 200uA, 2mA, 20mA, 200mA.
  • 2W ohms, 200, 2k, 20k, 200k, 2M, 20M, 200M, 2G ranges
  • 4W ohms, 2, 20, 200, 2k, 20k, 200k, 2M, 20M, 200M ranges
  • 6W ohms, 2, 20, 200, 2k, 20k, 200k, 2M, 20M ranges
  • Temperature measurements: RTD, -200°C to +1000°C, Thermocouples T,K -200°C to +1000°C
  • Simple AC measurement features, up to 400VAC (prolly base on AD637JR as TRMS converter)
  • PASS/FAIL Function
  • Ratio measurement function
  • Configurable buzzer
  • Digital inputs/outputs (8bit + 8bit)
  • Digital side: NXP Cortex MCU, ALTERA FPGA.
  • USB, RS232, Bluetooth interfaces. Maybe Ethernet, but that's for sure last-last option.
  • 100W linear power supply (25W display, 30W analog stuff, 25-30W heaters, 15W for anything else)
  • Fanless
  • 4-layer PCBs
  • Extensive internal monitoring (temperature sensors, voltage sensors)
  • Maybe battery option for voltage references (to keep them hot at least 24-48 hours during transportation for example)
  • Software support - LabView on host PC.
  • Low-noise mode (noisy devices switched off, remote controls only?)

Wanted software/firmware developers for this hobby project :)
Limited hardware samples might be possible.
