Self Test
Self Test Overview
Self Test Overview
Self Tests are a series of internal tests designed as a diagnostic tool to check
instrument hardware functionality and basic performance under controlled
conditions. If the test results fall within predetermined limits a pass is reported.
Self Tests do not require the signal generator to be adjusted before they will
pass. This means that some instrument performance failures may not be
detected or reported as a Self Test failure.
Self Tests should be run before, and after, an assembly has been replaced.
If the signal generator powers up despite having a hardware issue or any
performance verification failure, troubleshooting should always start with
running the Self Test and resolving reported failures.
Not all Self Tests are run on all models of the X-Series signal generators.
Depending on the installed standard and optional hardware, specific Self Tests
are activated and made available.
