Test Procedure
1.
Toggle 2074 trigger slope from positive to negative visa versa
2.
Verify on the oscilloscope that the 2074 transitions are
synchronized with the slope of the trigger

Test Procedure
1.
Verify that the 2074 outputs triggered waveforms spaced at 0.1
ms
2.
Modify the function generator offset to +2 V and change the
2074 trigger level to +4 V. Verify that the 2074 outputs triggered
waveforms spaced at 0.1 ms
3.
Modify the function generator offset to -2 V and change the
2074 trigger level to -4 V. Verify that the 2074 outputs triggered
waveforms spaced at 0.1 ms
