6-153. Adjusting the Edge Aberrations for Board 5500A-4004 Follow this procedure only if you have Board 5500A-4004 (Fluke PN 937383). 1. Adjust the dc offset on the 11801B so the peak of the square wave is on the center line.
Page 247 SC300 Option SC300 Hardware Adjustments for the A4 Board Typically this board shows aberrations of 1%. Note Aberration adjustments are interactive with rise time adjustments. When you have completed this aberration adjustment, verify the edge rise time to ensure that it remains within tolerance. If it does not, repeat the aberration and rise time adjustments until you achieve the best compromise, within the listed tolerance levels.

5500A Service Manual 6-154. Adjusting the Rise Time for the Edge Function This procedure adjusts the edge rise time, and must be performed after repair. Both boards use the same procedure to adjust the rise time. 6-155. Equipment Setup Before you start this procedure, program the Calibrator Mainframe to output 250 mV p- p @ 100 kHz.
