Test Procedure
1. Perform Offset Accuracy tests on all channels using Table 6-5
Table 6-5, Offset Accuracy
Error Limits CH1
4.000 V ±45 mV
1.500 V ±20 mV
0 V ±20 mV
-1.500 V ±20 mV
-4.000 V ±45 mV
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.
Equipment: Oscilloscope, 50 Ω, 20dB feedthrough attenuator
Preparation:
1. Configure the Oscilloscope follows:
