Setting Up a Data Pattern

Imagine, you have designed a new digital circuit with ECL logic and

3.3 GHz clock, and you want to check its correct behavior.

To test it, you decide to simulate a 32-bit pattern signal with NRZ

data output format:

11110011100110010010100100000000

Now let’s set the instrument parameters

Whenever you change a parameter, the generated signal immediately changes.

To protect your DUT, make sure you disconnect the channel outputs first.

Do this by pressing the softkey next the following function:

Protect the DUT

The open contactor shows you

that your DUT is now disconnected

First, disconnect the outputs

to protect the DUT

Select the Unit

Choose the Pulse/Pattern Mode

for the Signal

These define the signal that will be generated.

Enter the Frequency value

using the keypad

1 2 3 4 5 6 7 8 9 10 11 12
