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 the strobe input check are
structured as a continuous test. After the Check Event Input with Strobe Off test
is complete, the Check Strobe Input test uses the connections and oscilloscope
settings from the Check Event Input with Strobe Off test.
Equipment
required
AĂ50ĂW SMAĂcoaxial cable,ĂaĂSMA (female)ĆBNC (male)Ăadapter and
oscilloscopeĂ(TDS784D), and customĆmade ground closure. See Figure
4-3 for the connections.
Prerequisites The AWG710 Arbitrary Waveform Generator must meet the
prerequisites listed on page 4-8.
Do the following steps to install the test hookup and set the test equipment controls:
1. Use a 50 W SMA coaxial cable and a SMA(Fe)-BNC(Fe) adapter to connect
the AWG710 Arbitrary Waveform Generator CH1 output connector to the
oscilloscope CH1 input connector (see Figure 4–20).
