Sine tests apply either a single frequency or sweep for the operator to evaluate a unit's distortion. It can also apply a single frequency so NWin can measure the unit's output level.
Prompt - The text specified is presented to the operator at the test end in the form 'Prompt (Y/N)?'. Whether 'Y' or 'N' is a pass is set by Yes/No on the main test window. We have found that on the whole operators are less intimidated if asked to confirm a unit isn't a bad one rather than affirm it's a good one. Whilst waiting for the operator's response NaTKiT will continue to apply whatever is the last tone of the test.
- When set only the Low
(Hz) frequency and NWin, not
the operator, decides pass or fail by measuring the input and applying it to the
High Limit (dB) - The upper limit and can be set in the range 0 - (Low Limit (dB) + 1) dB.
Low Limit (dB) - The upper limit and can be set in the range -99 - (High Limit (dB) - 1) dB.
