Digital Telemeter

Key characteristics of DT include :

• 2, 4 or 8 channel wireless versions are now available
• The telemetric headstage features include:
  • small size and low power consumption
  • wireless operation time depends on battery (for example, 4 hours operation with 8 gram rechargeable coin cell; 8 hours with 35 gram battery; etc.)
  • operates with on-subject battery, or two wire supply for recordings of unlimited duration
  • working range between transmitter and receiver up to10 m
  • signal digitized at the subject, and available at the receiver either in digital form for direct processing, or as analog outputs that can be fed into virtually any recording system
  • this means the DT can simply plug in to replace existing headstages and tether cables in virtually any recording system
  • DT works well even in noisy lab environments
  • normal data direction is from subject to recording system, but up to four additional digital signals can be sent back to the subject, allowing for wireless stimulation or triggering of reward devices (optional current source or other interface circuit required)
• Three receiver versions:
  • with analog outputs compatible with most existing recording systems
  • with digital outputs for Axona dacqUSB recording systems
  • as a complete standalone recording system for any PC with a USB port

Key benefits of DT include :

• DT is wireless and miniature which gives the researcher more flexibility in designing experiments
• DT replaces a rack of analog amplifiers
• DT is superior to the 12- or 16-bit PC-based analog-to-digital converters of conventional recording systems. The electrode signals are digitized right at the headstage, with 24-bits of resolution, and then transmitted using digital techniques that guard against any noise pickup between the subject and recording system
