96A V\/F preamp adjustment summary<\/h2>\n

This post explains how to calibrate your 96A V\/F amplifier that is\u00a0 used on PHI Auger and XPS surface analysis systems.\u00a0\u00a0 You will need a voltmeter, an oscilloscope, a 30 Meg ohm test resistor and two clip leads.<\/p>\n

\u00a096A V\/F preamp Calibration procedure<\/strong><\/p>\n

    \n
  1. Turn off the 32-100 electron multiplier supply (or the card rack power)<\/li>\n
  2. Remove the HV POS In, POS out and COL cables from the 96A V\/F preamp<\/li>\n
  3. Remove the 96A V\/F preamp cover.<\/li>\n
  4. Turn ON the 32-100 electron multiplier supply (or the card rack power)<\/li>\n
  5. Measure voltage between L1 and L2, should be 28 to 30V DC<\/li>\n
  6. Adjust R23 for 0V betweenTP2 and HV POS in.<\/li>\n
  7. Adjust R18 for zero Hz on Frequency output<\/li>\n
  8. Adjust R37 for 0V on Analog output<\/li>\n
  9. Connect 30 Meg ohm load resistor between L2 and the COL resistor<\/li>\n
  10. Adjust R8 for 1MHz on the frequency output<\/li>\n
  11. Adjust R28 for 10V on the Analog output<\/li>\n
  12. Remove the 30 Meg ohm load resistor<\/li>\n
  13. Adjust R18 for 100 Hz on the Frequency output<\/li>\n
  14. AdjsutR37 for .1V on the Analog output<\/li>\n
  15. Repeat steps 5 through 10.<\/li>\n
  16. Turn off the 32-100 or card rack power.<\/li>\n
  17. Replace the cover on the 96A V\/F preamp.<\/li>\n
  18. Reconnect the HV POS In, POS out and COL cables to the 96A V\/F preamp<\/li>\n<\/ol>\n
