QPHY-HDMI Variables

E

XECUTION

O

RDER

M

ODE

Choose between CablingOrdered and IndeOrdered to define how the tests will be run. Currently
only IndexOrdered is available.

D

EMO

M

ODE

Select demonstration mode. When enabled, previously stored HDMI waveforms will be used.

HDMI

VERSION TESTED

Select HDMI Compliance test version. There are two versions available: 1.4 and 1.3.

N

UMBER OF SWEEPS ACQUIRED FOR A MEASURE

Increase the number of sweeps to increase precision. Decrease for speed. Choose between 1,
5 or 10. Default is 10.

U

SER DEFINED SIGNAL VERTICAL GAIN

If set to default (or negative value), the script will initiate an automated find scale to determine
the gain and offset. If set to a positive value, it will be used to set the gain of all signals and the
"Re-use vertical settings" variable will be ignored. Default is 0.

U

SER DEFINED SIGNAL VERTICAL OFFSET

If variable is defined (> 0), this offset will be used for the signal and trigger levels.

R

E

-

USE VERTICAL SETTINGS

Enable re-use of memorized vertical settings (to speed up test). Choose between Yes and No.
Default is No (disabled) to ensure gain and offset are correctly set. This variable is ignored if
"User defined signal vertical gain" > 0.

S

AVE ACQUIRED WAVEFORMS

Saved waveforms can be used later in demonstration or optimized version of script. Choose
between Yes or No. Default is No. This setting is ignored (no save) if using stored waveforms is
enabled and in Demo mode.

S

ILENT MODE CONTROL

Turn on/off user interaction. Useful to let the test run repetitively in the background. Choose
between Yes or No. Default is No.

TMDS

D

ATA

P

AIR TO TEST

Define which Data Pair to test. Connect TMDS DATA + to C1 and DATA - to C2. Choose
between D0, D1, D2 or D1,D2,D3. The last option is the default and will test all Data Pairs.

U

SE STORED TRACE FOR PIXEL CLOCK MEASURE OPTIMIZATION

Use to measure the pixel clock frequency only once. Choose between Yes and No, Default is
No.
