Overview

Use the DVI and HDMI analyzer option to test source

products, such as set-top boxes, as well as repeaters

and cables. Source product manufacturers will find this

option invaluable for verifying signal quality, timing, color

encoding, and E-EDID/E-DDC/HPD-related behavior.

The analyzer option adds a digital video receiver to the

base instrument. This receiver emulates a sink device

(display), while the generator output emulates a source

(host) device. The receiver presents an on-the-fly re-

programmable E-EDID to the source, and analyzes

incoming video for data errors and timing anomalies. The

receiver can analyze video from the instrument itself or

from an external source. Results can be displayed on the

connected monitor or generator LCD.

The HDMI and DVI analyzer option converts the incoming

digital signal to an analog signal, which can be connected

to an analog display for monitoring incoming content. The

analyzer also routes incoming audio to a SPDIF output,

which can be connected to an external digital speaker or

audio analyzer.

Signal quality can be measured without meticulous

inspection of a display screen. The analyzer accepts stan-

dard QDI-BCM pseudo-random noise test patterns, which

allow overall signal quality to be measured and expressed

in simple objective terms. In cases where the analyzer is

connected to a video source that does not support the

rendering of pseudo-random noise data, a “delta error”

measurement technique can be alternately used, which

counts flickering pixels in still-frame test images. Detailed

pixel-by-pixel analysis is also supported for checking

color encoding, scaling, and masking in test images.

Timing can be measured, independent of video content.

The analyzer option is also excellent for finding problems

with repeaters, cables, cable extenders, and distribution

systems. Everything needed to test transmission systems

from end-to-end, using pseudo-random noise or test

images, is now available in a single instrument.

Signal Analyzer Features

> EEPROM Emulator emulates an EEPROM (up to

8 blocks) with rapid on-the-fly re-programmable

E-EDID for testing how source devices respond to

different sink devices.

> Hot-Plug Generator generates hot-plug events

in concert with E-EDID changes.

> Timing Analyzer measures timing of external

video signal.

Measurements: pixel rate, fields-per-frame, H

and V rate/total/active, sync delay/width/polarity/

H-to-V alignment

Machine Unit Accuracy: zero tolerance

Frequency Accuracy: < 0.3%

> Pixel Data Analyzer measures pixel values and

detects flickering pixels in user-defined region of

1024 square pixels.

Error Tallies: delta errors (in static images)

Tally Range: 0 to 4095

> Packet Analyzer displays InfoFrame, general control,

audio sample, ACR, and generic data along with audio

channel status and errors.

> Pseudo-Noise Analyzer:

Noise type accepted: QDI-BCM

Error Tallies: Errors by channel (0, 1, and 2), total

pixel errors, floating-point pixel error rate (in errors-

per-billion)

Tally Range: 0 to 4095

PN Error Memory: One expected and one measured

24-bit value

Calibration: Pattern with known number of errors

(PRN_5 or PRN_9)

> AV Port for monitoring incoming HDMI signal, which

is output as YPbPr component analog video and SPDIF

digital audio.

> HDCP for functionally testing content protection

protocol (production key is provided).

Signal Generator Feature Extensions

The analyzer option enables these transmitter-

related features:

provided)

Sequence Length: manually set from 4 to (2^31-1)

pixels or automatically set to hActive*vActive

Bit-to-Bit Correlation: none

Noise Value Advance: manually choose between every

pixel and active pixels only or automatically set to

active pixels only

Sequence Repeat: continuous or stop after n=1

to 4,294,967,295 sequences

Seed Value: manually set form 0x00000001 to

0x7FFFFFFF or automatically set to 0x08000001
