qStep 6: In the Generator CLOCK section, the FREQUENCY LED should be on. If it is not, press the ‘FREQUENCY’ key to select it.

qStep 7: Use the Generator CLOCK up/down keys to change the output frequency.

qStep 8: Check that the frequency displayed by the Analyzer matches the Generator output to within ± 0.1 MHz. (Note that the resolution of the Analyzer is 0.01 MHz and that the resolution of the Generator is 0.001 MHz.

qStep 9: At the Generator, use the ‘STEP’ key to select another frequency step size (note the placement of the underscore on the Generator frequency display), and repeat steps 7 and 8 at this step size.

qStep 10: Repeat steps 7 through 9 for all step sizes.

Confirmation of Selectable Data Patterns

qStep 11: In the Generator PATTERN section, verify that the PRBS LED light is on. If not, press the PRBS key to select it.

qStep 12: Press the Generator PATTERN up/down keys to select PRBS pattern PN7.

qStep 13: Verify that the Analyzer displays the same PRBS pattern as the Generator.

qStep 14: At the Analyzer, press the ‘CLEAR’ key in the ERROR HISTORY section.

qStep 15: Verify that the four ERROR HISTORY LEDs are off and stay off.

qStep 16: At the Generator, use the PATTERN up/down keys to select the next PRBS pattern.

qStep 17: Repeat steps 13 through 16 for each of the five PRBS patterns.

qStep 18: In the Generator OUTPUT section, press the ‘INVERT DATA’ key. The INVERT DATA LED will light.

qStep 19: Verify that the INVERT DATA LED in the Analyzer INPUT section is also on.

qStep 20: Repeat steps 12 through 17, noting that INV is displayed after the PRBS pattern on the Analyzer display.
