Event Input and Enhanced Mode Tests
These procedures check the event input signals and enhanced mode operation.
NOTE. The event input check with strobe off and strobe input check are struc-
tured as a continuous test. After Check Event Input with Strobe Off, the next test
uses the connections and oscilloscope settings from the last test.
Equipment
required
A 50ĂΩ coaxial cable, an oscilloscope, and customĆmade ground
closure.
Prerequisites The AWG500-Series Waveform Generator 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 CH1 output connector through the coaxial cable to the
oscilloscope CH1 input connector (see Figure 4–21).
