Sinewave
Characteristics
This tests the characteristics of the sine waveform. It includes
distortions, spectral purity and flatness. Each channel has its own set
of amplifiers and attenuators and therefore, the characteristics are
tested on each channel separately.
Sinewave
Distortions Equipment: Distortion Analyzer, Spectrum Analyzer, and
ArbConnection
Preparation:
1. Connect 2074 Channel outputs to the distortion analyzer input.
2. Configure the 2074 as follows:
SCLK: As required by the test
Waveform: Arbitrary
Amplitude: 5
V
Output: On
3. Using ArbConnection prepare and download the following
waveform:
Wavelength: As required by the test
Waveform: Sinewave
Test Procedure
1. Perform Sinewave distortion tests on all channels using Table
6-7
