Requirements and Restrictions

Do not change the oscilloscope settings when the test runs. If you change the settings when the test runs, the software may give abnormal test results.
Prerequisites
TekVisa must be installed on the oscilloscope. If you do not have TekVisa,
you can download it from http://www.tek.com/site/sw/detail/1,1059,2704,00.html.
If the signal is not connected and the noise level is less than 50 mV, then the
software detects and displays a message such as 'Improper Waveform.'
For better and reliable results
Before you run any test, calibrate the probes and oscilloscope for Signal
Path Compensation.*
8
If the signal is not connected and the noise level is less than 50 mV, then the
software detects and gives a message such as 'Invalid Signal.'
* To calibrate an oscilloscope, on the oscilloscope menu bar, click Utilities > Instrument Calibration, and then click Calibrate.

This happens due to the following reasons:
1. Oscilloscope bandwidth is less than 4 GHz. For higher resolution HDMI
signals, you need at least a 4 GHz oscilloscope. Your oscilloscope bandwidth is less than 4 GHz. You cannot measure less than 1 ns Tbit signals accurately.
2. Serial Pattern Trigger option is not available. Source Intra-pair skew test
requires serial trigger (Option ST) but it is not found in the oscilloscope. You cannot perform the Source intra-pair skew test.

3. Maximum available record length for two channels is less than 16 M.
For HDMI compliance testing, you need at least 16 M record length in two channels. This is available with Option 4 M or above, but it is not available in the installed oscilloscope. The software runs the eye and jitter measurements with the maximum available record length.
Depending on the type of oscilloscope that you have, you can start the software in different ways.

Select different physical channels (A1, A2, B1, B2, C1, C2, D1, D2) for a given logical channel (Clock, Data0, Data1, Data2).
Switch on the AWG and wait for the AWG software to load. Check GPIB connections. Ensure that the primary address of AWG in the Utility > Network > Address matches with the GPIB-ENET configuration of the oscilloscope. Ensure that the GPIB­ENET configuration on your oscilloscope matches the signal sources configuration in the software.

connection.
194 Jitter value is unavailable. Signal is not probed at the proper
201 Edges on the Wfm are lesser than
the configured number of edges.
202 Calculated skew is greater than the
oscilloscope skew range.
203 Cycle has less than 20 sample
points.
Signal sources connection has failed. It may be due to DTG or AWG connection failure. DTG connection has failed. This could happen if:
The DTG is not switched on There is a mismatch in the GPIB-
ENET configuration, software GPIB configuration, and DTG remote control configuration
If the GPIB cable is not connected properly.
AWG connection has failed. This could happen if:
The AWG is not switched on There is a mismatch in the GPIB-
ENET configuration, software GPIB configuration, and AWG remote control configuration
If the GPIB cable is not connected properly
Primary addresses of DTG and AWG are same.
test points.
Deskew number of edges set by the user to perform the deskew is not available on the waveform.
The calculated skew value is greater than the oscilloscope deskew range.
Insufficient number of samples in a complete cycle. The number of data points in the identified cycle is less than 20 data points.
For DTG connection failure: Switch on the DTG and wait for the
DTG software to load. Check the GPIB connections. Ensure that the primary address of DTG in the remote control matches the GPIB­ENET configuration of the oscilloscope. Ensure that the GPIB­ENET configuration on your oscilloscope matches the signal sources configuration in the software.
For AWG connection failure: Switch on the AWG and wait for the
AWG software to load. Check the GPIB connections. Ensure that the primary address of AWG in the Utility > Network > Address matches with the GPIB-ENET configuration of the oscilloscope. Ensure that the GPIB-ENET configuration on your oscilloscope and signal sources configuration
in the software match.
Select distinct primary addresses for DTG and AWG.
Follow the instructions in the setup diagram and probe the proper signal.
Ensure that the edges in the waveform and the display in the numeric input are the same. Adjust the horizontal scale to increase the number of transition that is required to adjust the deskew.
The deskew will be done to the maximum deskew value that is applicable to the oscilloscope.
Increase the sampling rate.
