4DISPLAY5 DSP LINE ON OFF (ON)

Adjust the display line so that it is centered on the average trace noise, ignoring any residual responses (refer to the Residual Responses veri￿cation test for any suspect residuals).

9.Record the display line amplitude setting as TR Entry 1 of the performance veri￿cation test record as the noise level at 400 kHz. The average noise level should be less than the speci￿ed limit.
