H Turn the general purpose knob to select the CLK_FREQ.WFM file.
H Push ENTER.
3. Check clock frequency accuracy:
a. Check clock frequency accuracy at current clock frequency setting:
Check that the frequency counter reading falls between 249.9875 MHz
and 250.0125 MHz.
b. Check clock frequency accuracy for different clock frequency settings:
H Select Clock from the bottom of the SETUP menu.
H Turn the general purpose knob (or press the numeric and units keys,
and push ENTER) to select the first clock frequency listed in Table
C-3.
H Check that the frequency counter reading is within the frequency
