Squarewave
Characteristics
This tests the characteristics of the square waveform. It includes
transition times, aberrations and skew between channels. Each
channel has its own set of amplifiers and attenuators and therefore,
the characteristics are tested on each channel separately.
Squarewave Checks Equipment: Oscilloscope, 50
Ω
, 20dB feedthrough attenuator
Preparation:
1. Configure the Oscilloscope follows:
Termination: 50
Ω
, 20 dB feedthrough attenuator at the
oscilloscope input
Setup: As required for the test
2. Connect 2074 Channel outputs to the oscilloscope input
Configure the 2074 as follows:
Frequency: 1 MHz
Waveform: Squarewave
Amplitude: 5
V
Output: On
Test Procedure
1. Perform Squarewave Characteristics tests on all channels using
