Tests on hi-fi components call for increasingly complex measurement techniques. Results obtained in the test lab must be verified in production, which usually requires economical solutions for handling large batches rather than the use of all available functions. The R&S UPL is an ideal choice for this task. It optimally complements its “bigger brother“,the Audio Analyzer R&S UPD, which is mainly employed in development. The two units share the exact same IEC/IEEE bus commands, which means they have the same operating concept and can be used together.

N Realtime display of results for one or both channels and several test functions. N Simultaneous display of frequency and phase. N With graphics, results can be read off with vertical and horizontal cursors. Tolerance curves or stored results can be added for comparison. N Sets of traces can be displayed, stored and evaluated for both channels. N Graphics options include traces and bargraphs, spectrum display, and three-dimensional waterfalls.

In many cases only a few parameters need to be modified after a measurement sequence has been started. Therefore, entry lines can be selected from the input panels for the generator, analyzer, etc, by means of a checkmark. They are then transferred to a status panel. The status panel thus gives a summary of parameters for a measurement routine, which offers the following advantages:

N Instrument settings can be displayed together with graphical and numeri- cal results. N All important information can be printed on a single hardcopy. N Instrument settings can be modified quickly without changing panels as the R&S UPL can also be operated from the status panel.
