Amplitude accuracy checks tests the accuracy of the output amplifier
and attenuators. Each channel has its own set of amplifiers and
attenuators and therefore, the accuracy is tested on each channel
separately.
Equipment: DMM
Preparation:
1. Configure the DMM as follows:
Termination:
Function:
2. Connect 2074 Channel outputs to the DMM input
3. Configure the 2074 as follows:

Offset accuracy checks tests the accuracy of the offset generators.
Each channel has its own set of offset generators and therefore, the
accuracy is tested on each channel separately.
