including the characteristics and signal connections
for the USB Analysis Probe module.
Characteristics
The following operating characteristics are not
specifications, but are typical operating characteristics
for the USB Analysis Probe.
Standards Supported
The Universal Serial Bus Specification Revision 1.0
Power Requirements
The USB Analysis Probe does not draw power from
the USB wire. All power is provided by the logic
analyzer.
Logic Analyzer Required
166x, 167x, 1655x
USB State Analysis - 2 PODS
Number of Probes Used
USB Timing Analysis - 3 PODS
Supported speeds
The USB Analysis Probe supports both full speed and
low speed operation.
Signal loading
The USB Analysis Probe presents one USB
transceiver load onto the USB. The Analysis Probe
IN and OUT connectors (D+, D-, GND and VCC) are
daisy chained so that the USB traffic is not
interrupted.
All signal etch length, trace velocity and impedance is
within specification.
