2. Set the AWG500–Series Waveform Generator controls:
a. Initialize the AWG500–Series Waveform Generator controls:
Push UTILITY (front–panel)!
System (bottom)!Factory Reset (side)!OK (side).
b. Select waveform file for DIGITAL:
H Push the DIGITAL button.
H Select the waveform for the DIGITAL: Load the DOUT.PAT as
referring to the procedures on page 4–15.
c. Set the digital data output low level:
H Set the low level: Push VERTICAL MENU (front–panel)!
Low Level (side).
H Enter numeric value of –2: Push –, 2 and ENTER keys in this order.
d. Turn on the digital data out: Push the Output side button so that the
Output is set to On.
3. Turn on the AWG500–Series Waveform Generator output: Push the RUN
button so that the LEDs above the RUN button lights.
NOTE. At the output level measurements from an oscilloscope, do not measure
the high and low level voltages that contain the ringing by overshoot or
undershoot. Always perform the measurements after the level has been stabled.
4. Check the digital data output level accuracy:
a. Check the D0 output level:
H Check the low level: Check the reading for the low level on the
oscilloscope screen is within the range between –2.2 V and –1.8 V.
H Check the high level: Check the reading for the high level on the
oscilloscope screen is in the range between 1.8 V and 2.2 V.
b. Check the output level from D1 to D9:
H Change the cable connection: Disconnect the SMB-to-BNC cable
from the DIGITAL DATA OUT:D0 connector and connect it to the
