MODEL 6050 PIEZOELECTRIC CARD
• Complete piezoelectric signal conditioner with 16-bit
analog-to-digital converter
• Supports both VM (voltage mode, low impedance) and CM
(charge mode, high impedance) type piezoelectric
transducers
• Programmable constant current excitation supply for VM
transducers is software settable to 1, 2, 4, 5, 10 and 20mA
• Programmable gain steps of 1, 2, 5, and 10 for VM
transducers and steps of 1, 2, 5, 10, 20, 50 and 100 for CM
transducers
• Programmable digital filter
• Fixed low-pass anti-aliasing filter (six-pole)
• Input connections to user's transducer via BNC connector
