Operating Mode Tests
The following procedures verify the operation of the Cont, Triggered and Gated
modes.
NOTE. When you output signals from the CH1 or CH1
OUTPUT, check that
the other OUTPUT ( CH1
or CH1 ) LED is off. If the other OUT-
PUT LED is on, push the CH1
or CH1 OUT button to turn off the output.
Equipment
required
A50W SMAĂcoaxial cable,ĂaĂSMA (female)ĆBNC (male)Ăadapter, and
an oscilloscopeĂ(TDS784D).
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 to connect the AWG710 Arbitrary Waveform
Generator CH1 output connector to the oscilloscope CH1 input connector
(see Figure 4–5).
