2.Select the AWG2021 waveform file, and set AWG2021 controls:

a.Initialize AWG2021 controls: Push UTILITY￿Misc￿Config...￿Re- set to Factory￿O.K.

b.Select waveform file:

￿Push SETUP￿Waveform Sequence, if necessary, to select a waveform file for CH1.

￿Turn the general purpose knob to highlight the DIGI_OUT.WFM file.

￿Push ENTER to select the file.

c.Set AWG2021 controls:

￿Push MODE￿Cont

3.Turn on the AWG2021 CH1 output: Push the CH1 button so that the LED above the CH1 output connector is on.

4.Check the digital data output signals:

a.Enable power supply output: Turn on power supply output.

b.Check the signal levels:

￿Contact the oscilloscope probe to the pins on J200 and J210 (see Figure C-21). Check that the oscilloscope display shows these signals:

Data signals D0±D11, D0±D11 are differential ECL output. Clock signals CLK and CLK are differential ECL output. All other pins are ground.
