19 Select the Best Sensitivity Sampler Bandwidth. Close dialog box.
20 On the DCA screen, press Time Delay, then check the period at the scale and synthesized CW
generator settings shown in Table 2-2 and record the results in the Performance Test Record.
a Press the Clear Display hardkey and wait for the averaging to complete before recording the
