Neurodiagnostic Instruments Service Manual
3 - 60 Revision 2/18/05
The digitized patient signal is transferred to the host PC
via a Universal Serial Bus (USB) port. Information for
synchronizing the data with stimulus events is placed
into the data stream as well.
Control and status information from the host PC to the
amplifier are exchanged along with the data on the
single USB interface cable.
Testing
The VikingQuest USB Diagnostics are the primary tool
for testing the amplifier system. The AutoTest checks
communication with the analog to digital converter on
the VikingQuest’s base board. The Headbox Test uses
the Trigger Out pulse to check the signal path integrity
farm the electrode input connectors on the preamplifier
to the host computer.
