D1 connector. Proceed this step as changing the cable connection
from D1 to D9
H Check the low level, high level and period: Do the procedures in step
4.a for each of DIGITAL DATA OUT connectors from D1 to D9.
5. End procedure: Retain the AWG520 settings.
Equipment
required
Two 50ĂΩ SMBĆtoĆBNC coaxial cables (same length), 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 and D1 outputs through 50 Ω
SMB-to-BNC coaxial cables with the same length to the oscilloscope
CH1 and CH2 input connectors, respectively (see Figure 4–35).
