Multi-application data display
First Claim
1. A test instrument for acquiring and displaying motor vehicle data, comprising:
- a scan interface component permitting communication between said test instrument and a motor vehicle onboard diagnostic (OBD) computer;
an external device interface component permitting communication between said test instrument and an additional data acquisition device; and
a communication subsystem that establishes communication between said scan interface and said external device interface components, said subsystem acquiring data from said scan interface and from such additional data acquisition devices as said external device interface component may be in communication with.

Abstract
A data display firmware improvement for a scan tool adds the capability to view in a single presentation data uploaded from a motor vehicle'"'"'s onboard diagnostic (OBD) computer synchronized with data from external test apparatus. The data display algorithms permit viewing of OBD data, including certain real-time oscilloscope-like waveforms, and allow viewing test results from compatible instruments, such as exhaust gas analyzers, including capturing realtime OBD signals, holding them until delayed events such as gas analyzer test results become available, then displaying the events on a common display as though available simultaneously in real time. The firmware upgrade is downloadable to existing products.
