Individual Test Description

1. Frequency Accuracy Test

Description
This test checks the frequency accuracy of the E4980A/ E4980AL test signal.
The frequency accuracy is checked at 1MHz with a frequency counter. Since
the E4980A/ AL employs a Direct Digital Synthesizer for the signal source, the
frequency accuracy test at this frequency point can verify the accuracy for the
entire frequency range.

2. DC Source Level Accuracy Test

Description
This test checks the DC source level accuracy of the E4980A/ E4980AL DC
source port output signal.

3. DC Bias Level Accuracy Test

Description
This test checks the DC bias level accuracy of the E4980A/ E4980AL DC bias
signal.

4. DC Bias V Level Monitor Accuracy Test

Description
This test checks the DC bias V level monitor accuracy of the E4980A/ E4980AL.
(Option: 001 only)

5. DC Bias I Level Monitor Accuracy Test

Description
This test checks the DC bias I level monitor accuracy of the E4980A/ E4980AL.
(Option: 001 only)

6. AC Signal Level Monitor Accuracy Test

Description
This test checks the AC signal level monitor accuracy of the E4980A/ E4980AL.
