Performance Verification Procedures
This procedure uses the following convention to differentiate between front-pan-
el hard keys and displayed soft keys; hard keys are displayed in bold, and soft
keys are bold enclosed with < > symbols. For example: Measure hard key, and
<H_Timing> soft key.
The VM700A Auto Measure mode is used in this procedure. If you cannot find a
specific measurement in Auto mode, check that the measurement is selected in
Audio Outputs
