AWG510 & AWG520 Service Manual
Digital Data Output Tests (Option 03 Only)
These procedures check the AWG500–Series Waveform Generator digital data
output level accuracy and skew.
Equipment
required
A 50ĂΩ SMBĆtoĆBNC coaxial cable, and an oscilloscope.
Prerequisites The instrument must meet the prerequisites listed on page 4-13.
1. Install the test hookup and set test equipment controls:
a. Hook up the oscilloscope: Connect the AWG500–Series Waveform
Generator DIGITAL DATA OUT:D0 output through a 50 Ω SMB-to-
BNC coaxial cable to the oscilloscope input connector (see Figure 4–34).
Connect the SMB
connector end to DIGITAL
DATA OUT:D0 connector
Oscilloscope
