Reverse Engineering the PDA-100 PHOTODIODE ARRAY DETECTOR

Absorption detector capable of measuring the absorbance spectrum from 190 nm to 800 nm. A deuterium lamp optimizes the UV range (190 nm to 380 nm) and a tungsten lamp optimizes the visible range (380 nm to 800 nm).

PDA-100 Features:
- Deuterium and tungsten lamps
- wavelength range from 190 nm to 800 nm
- 1024-element photodiode array optimizes spectral resolution
- built-in holmium oxide filter verifies wavelength calibration accuracy

Four analog outputs

To power the lamps:
Pin 12 needs to powered with a CLOCK signal for the High Voltage transformer. Don't know the exact frequency (can someone measure, please?). Works for me with 20KHz.

Sequence to power the Deuterium: Set high voltage to about 25% (4V), LED NO/F lights up. Then turn "D2 Fil" up until NO/F light goes off, ignition flash, D/OK should light green. Then turn D2 Fil down to zero again.
