2. Set AWG2021 controls and select the waveform:
a. Initialize AWG2021 controls: Push UTILITY!Misc!Config...!Re-
set to Factory!O.K.
b. Select the waveform file:
H Push SETUP!Waveform Sequence, if necessary, to select a

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/Divider from the bottom of the SETUP menu, or select
Clock if the instrument is not equipped with Option 02.
H Turn the general purpose knob (or press the numeric and units keys,
and push ENTER) to select the first clock frequency listed in
