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.*

 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.

Tbit is the time that is required to transmit one bit of data. Tbit is one bit time at the specified pixel clock frequency (= T

For all the tests that require clock, the software calculates Tbit. For all the other tests, you have an option of either recalculating Tbit or use the previous tbit value for the test.

If you click Re-calculate, the software computes the specified number of averages of T then the software uses the previously calculated Tbit value or you can also again recalculate Tbit by using the tbit pane.

To calculate Tbit for a measurement, use the tbit pane. You can calculate Tbit for Duty Cycle, Rise Time, Fall Time, Over/Undershoot V-H, Over/Undershoot V-L, Inter-Pair Skew for Clock-Data Tests, Inter-Pair Skew for Data-Data Tests, IntraPair Skew, Low Amplitude +, and Low Amplitude - measurement if the clock is not connected.
