4-78 AWG510 & AWG520 Service Manual
Noise Output Tests
This procedure checks the AWG500–Series Waveform Generator noise output
characteristics.
Equipment
required
A 50ĂΩcoaxial cable, a DC block, an adapter (N male to BNC female),
and a spectrum analyzer.
Prerequisites The instrument mustmeet the prerequisites listed on page 4-13.
1. Install test hookup and set test equipment controls:
a. Hook up the spectrum analyzer: Connect the AWG500–Series Waveform
Generator NOISE OUT connector through the coaxial cable, adapter,
and DC Block to the input connector on the spectrum analyzer (see
Figure 4–37).
