Tektronix UPL06

This Analyzer performs all measurements using digital signal processing.

Analog signals to be tested undergo elaborate preprocessing before they are digitized and measured by means of digital routines.

For example, in THD measurements, the fundamental is attenuated by means of a notch filter and the residual signal amplified by 30dB before it is digitized.

In this way, the dynamic range can be extended beyond that offered by the internal 20 bit converter.

This provides sufficient margin for measuring converters of the future, which will be more advanced than those with present day technology (see graph on
the right).

This concept ensures performance and flexibility by far superior to instruments providing purely analog or digital measurements.
