LVDT driver characterization (not final)

 

  • Input signal: 4.86 Vpp at 10 kHz.
  • The input gain is the ratio of the amplitude measured at the probe point over the amplitude of the reference signal.
  • For some devices the phase was set to zero by visual inspection using an oscilloscope.
  • Phase measurements were recorded in photos which are uploaded to NAOJ's Google Photos.
LVDT Input gain Output gain resistance (Ohm) Phase (µs) Board and probe point
BF 0.975 57.1 21, signal ahead left board, P0
SF 0.977 57.5 20, signal ahead left, P1
F0 0.975 Yet to be set zero left, P2
IP #1 0.975 Yet to be set zero right, P0
IP #2 0.975 Yet to be set zero right, P1
IP #3 0.971 Yet to be set zero right, P2
