10.Calculate the frequency settability by performing the following steps:
a.Calculate the frequency dierence between Counter Reading 2 and Counter Reading 1.
b.Calculate the frequency dierence between Counter Reading 3 and Counter Reading 1.
c.Divide the frequency dierence with the greatest absolute value by two and record the value as TR Entry 1 of the performance verication test record. The settability should be less than 6150 Hz.
d.Press 4PRESET5 on the EMC analyzer. The timebase DAC will be reset automatically to the value recorded in step 5.
