AWG510 & AWG520 Service Manual
Clock Output Tests
These procedures check the AWG500–Series Waveform Generator clock output
signal.
Equipment
required
A 50ĂΩ BNC 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 CLOCK OUT output through a 50 Ω BNC coaxial cable to
the oscilloscope input connector (see Figure 4–36).
Connect the BNC
connector end to
CLOCK OUT connector
