AWG510 & AWG520 Service Manual
Amplitude, Offset Accuracy and Rise Time Tests (Direct DA Out)
These procedures check the accuracy of the AWG500–Series Waveform
Generator direct waveform outputs; amplitude and offset.
Equipment
required
A 50ĂΩ coaxial cable, a 50ĂΩ precision terminator, a BNC (female)ĆtoĆ
dual banana adapter, and a digital multimeter (DMM).
Prerequisites The AWG500-Series Waveform Generator meets the prerequisites
listed on page 4-13.
1. Install the test hookup and set test equipment controls:
a. Hook up DMM: Connect the AWG500–Series Waveform Generator CH1
output through a 50 Ω BNC coaxial cable, a 50 Ω precision terminator,
and an adapter (BNC-to-dual banana) to the DMM input connector (see
Figure 4–11).
