Pseudo-random noise generation commands

This section provides command line procedures for generating pseudo-random noise.

Generating pseudo-random noise

The following is an example of using commands to first configure and then generate

pseudo-random noise.

To generate pseudo-random noise:

1. Using a terminal emulator, establish a terminal connection with the generator. Refer to

“Setting up a terminal connection with the generator” on page 14.

2. Enter the following commands to configure the generator to output a digital signal

(HDMI or DVI):

SROP 2 4

This removes analog friendly mode and configures the generator to output either a DVI

or HDMI signal depending on the interface hardware the generator is equipped with

(DVI or HDMI).

3. (optional) Enter the following command to set the status display mode:

SROP 8

4. Enter the following commands to generate pseudo-random noise.

PNSF 0 // selects internal timing source for pseudo-random noise

PNST 1 // specifies QDI-BCM algorithm

PNSA 1 // sets pseudo random noise to be calculated each pixel clock

PNSM 0 // sets pseudo random noise test to run in auto mode

PNSP 0 // sets procedure for pseudo-random noise test to “continuous”

PNSG 1 // enables the pseudo-random noise test

PNGU // turns on the pseudo-random noise test

<CR> // a carriage return halts the continuous test

5. Enter the following commands to stop pseudo-random noise generation.

PNSG 0

PNGU
