Event Input and Enhanced Mode Tests
These procedures check the event input signals and enhanced mode operation.
. 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).
