Packet-Master USB-PDT
Analyser Pod
The USB-PDT Analyser
Pod is an option for the Packet-Master USB-PDT to
allow it to be used as a non-intrusive Analyser for
PD-Communication between two third-party PD devices.
It is equally suitable for devices connected by a
separate PD cable, or for the case where one of the
devices has a captive cable.
The Pod is supplied
complete with a special cable to connect to the PDT.
A removeable VBUS link can be fitted with a suitable
wire loop for VBUS current measurements.
Pod Functionality
USB-PDT Analyser Pod
is fully featured and has no influence on Superspeed
signalling between the two devices under test.
Analyser Capture

During testing, the
entire sequence of PD messages is captured and displayed.
Each event is analysed in the Details pane. Every
bit field is analysed, described and any potential
non-compliances are highlighted.SOP', SOP'', SOP'_debug
and SOP''_debug messages are also displayed. The locations
of the packets and the scope captures, together with
voltage and current, are shown in the zoomable timeline.
