P-Scope Quick Start Guide – Rev. AP5 P/N 68-00214
Chapter 1 - Getting Started
This chapter provides an overview of the HDMI P-Scope. The P-Scope is an HDMI analyzer for HDMI
source devices. It provides visibility into the HDMI protocol to help resolve common interoperability
problems in HDMI systems.
What kinds of data does the P-Scope allow you to view?
By providing visibility into the HDMI protocol the P-Scope enables you to detect changes and anomalies
in the HDMI signal and to compare data types. The following is a list of the data types you can view
(currently):
Data Islands, including:
oInfoframes (AVI, Audio, Source Product Descriptor, etc.)
oGeneral Control Packet (GCP)
oAudio Clock Recovery (ACR)
oAudio Sample Packet
Timing parameters (examples)
oPixel rate
oVertical sync
oHorizontal sync

What is in the P-Scope shipping box
You will find the following items in the P-Scope shipping box:
Quantum Data P-Scope test instrument.
Ethernet crossover patch cable (P/N 30-00151) – used for connecting to the P-Scope over the LAN
interface.
Detachable power cable – used for powering the P-Scope.
HDMI cable (P/N 30-00146) – used for connecting to the P-Scope to the device under test.

Front Panel
The P-Scope front panel has two LEDs. The green LED is a power indicator; the yellow LED indicates
that the hard drive is being accessed. There is power up button to turn the P-Scope on (along with the
rocker switch on back). There are two (2) USB connectors which are not used and one firewire connector
that is not used.
Interface Description
The P-Scope (rear view shown in the photo below) provides an HDMI input for connecting to an HDMI
source device.
HDMI Rx connector (the top most HDMI connector shown in the figure below) enables you to monitor
the HDMI protocol from an HDMI source device.
HDMI Tx connector (the lower HDMI connector) is not currently functional.
Control Interface
There is an Ethernet jack on the lower half of the back panel of the P-Scope frame. This is used to
establish an IP session with the P-Scope application.

Chapter 2 – Overview of the P-Scope Application
Overview
This chapter describes the P-Scope application windows. The P-Scope is an application that runs on your
local PC.
Main Window
The main window is shown in the figure below (without any other windows open). The P-Scope window
enables you to close, maximize and right-size (float) any or all of its windows. You can also detach the
windows and drag them out of the main window.

Top level buttons and their functions
There are a series of top level buttons on the P-Scope graphical interface. These are described in the
following table:
Button Function
Capture Control Opens up the Capture Control window which enables you to capture data and
set up the triggers for capturing the data.
Frame Selector Opens up the Frame Selector window which enables you to select frames for
viewing.
Frame Data Chart Opens up the Frame Data window which enables you to view frame protocol
statistics and access lower level (more detailed) data.
Detailed Data Opens up the Detailed Data window which enables you to view the details of
each transaction for all lines in a previously selected frame.
Video Frame
Viewer
Enables you to see the video pattern that is active (sent in from the source) for
a particular frame.
Frame # Chart This button appears once you have accessed a specific frame from the Frame
Data Chart window. When it is present, clicking on it will open up the Frame #
Chart window which enables you to view protocol statistics for each line in the
frame. It also enables you to access the Detailed Data window to view lower

P-Scope Quick Start Guide – Rev. AP5 P/N 68-00214
The following table defines the items in the Trigger Setup window:
Item Type Options/Settings Description
No Trigger (One
Shot Capture)
The capturing of data begins when the Capture
button is pressed and ends when the frame
capacity, defined by the Frame Count slide bar,
is exhausted.
No Trigger
(Running Capture)
The capturing of data begins when you click the
Capture Data button and ends when you click
the Stop Capture button. The data that is
captured is the set of frames that end at the
stop capture point and extend back in time to
cover the set of frames determined by the
capacity of the buffer as defined by the Capture
Buffer % sidebar.
Capture
Method
Pull down:
Video Format
Change
The capturing of data begins at the initial
occurrence of the trigger event (a video format
change). A video format change is any change
in pixel rate beyond a threshold defined by
the % Clock Deviation parameter.
% Clock
Deviation
Slide Bar: 0 to 100% Defines what constitutes a Pixel Clock Change.
Expressed in percentage of the pixel rate. This
option is only available when you have selected
Video Format Change option is set to Trigger on
Pixel Clock Change.
# Frames
Before Stop
Slide Bar: 10 to 100 The number of frames that are captured after
the trigger criteria is met. This option is only
available when you have selected Video Format
Change option is set to Trigger on Pixel Clock
Change.
Begin Indicates that the data that is captured and
stored for later analysis is the data throughout
out a range which begins at the trigger point and
extends to the range of frame data whose
capacity is defined by the Capture Buffer %
setting.
Trigger
Position

Alpha release
Slide Bar:
Center Indicates that the captured data, stored for later
analysis, is the data throughout out a range
such that the amount of data is distributed
equally around the trigger point. In other words,
equal amount of frame data prior to the trigger
point as there is after the trigger point.

P-Scope Quick Start Guide – Rev. AP5 P/N 68-00214
End Indicates that the data that is captured, and
stored for later analysis, ends at the trigger point
and extends earlier in time to an amount of
frames determined by the Capture Buffer %
setting.
Slide Bar 0 – 100% Enables you to set a percentage of the
maximum number of frames for capture and
storage by sliding the bar to a particular value.
You can capture up to about 1150 frames at
576p/480p and about 204 frames at 1080p.
