2.Set AWG2005 controls and select the waveform:
a.Initialize AWG2005 controls: Push UTILITYMiscConfig...Re( set to FactoryO.K.
b.Select the waveform file:
Push SETUPWaveform Sequence, if necessary, to select a waveform file for CH1. Waveform Sequence toggles between the CH1 files (upper list) and the CH2 files (lower list).
Turn the general purpose knob to select the CLK_FREQ.WFM file.
Push ENTER to select the file.
3.Check clock frequency accuracy:
a.Check clock frequency accuracy at current clock frequency setting: Check that the frequency counter reading falls between 19.99996MHz and 20.0016MHz (between 19.9999 MHz and 20.0001 MHz for the instrument with Option 05).
b.Check clock frequency accuracy for different clock frequency set" tings:
Select Clock from the bottom of the SETUP menu.
Push Source from the side menu to highlight Internal.
Select Internal Clock from the side menu.
Turn the general purpose knob (or press the numeric and units keys, and push ENTER) to select the first clock frequency listed in Table 474.
Check that the frequency counter reading is within the frequen7 cy range listed in the table for the clock frequency setting (refer to right column in the table for the instrument with Option 05).
Repeat this step for each clock frequency and frequency range listed in Table 474.
