23 Set the Waveform Generator’s frequency to 10 MHz; set the amplitude to 400 mV pp, offset 0V,
square wave.
24 On the DCA screen, press Time Delay. Ensure that the delay is set to 24 ns, then check the period
at the Function/Arbitrary Waveform Generator and scale settings shown in Table 2-3 and record
them in the Performance Test Record.
25 Press the Clear Display hardkey before recording the new reading.
