OSCILLOSCOPE GAINS NEW OPTIONS FOR POWER-SUPPLY ANALYSIS AND USER-DEFINED MATH
Two new options – a power-supply analysis function and user-defined math capabilities – have been added to the range of enhancements available for the Yokogawa SignalXplorer DL9000 Series of digital oscilloscopes.
The power supply analysis function (Option /G4) includes automated measurements and statistical analysis of key parameters required for power supply design, including harmonics, switching loss, power factor, impedance, watt-hours and ampere-hours. When the power supply analysis function is installed, it includes the user-defined math function (Option /G2).

Key features include the correcting (de-skewing) of the difference in the transfer time of analysed signals. Using the de-skew correction signal source (Yokogawa model 701935), users can automatically or manually correct the difference in delay or response time between probes.
Waveform computation facilities include active power, impedance and Joule-integral calculations, with the results being displayed as computed (math) waveforms. Harmonic analysis on the power supply current can be carried out to test compliance with IEC 61000-3-2 and EN61000-3-2 (pre-compliance testing). It also supports the display of history and cycle statistics and trends.
With the user-defined math function (Option /G2), up to four equations can be defined using mathematical functions, differentials and integrals, trigonometry and other operations, and can be computed simultaneously. In addition to these operations, equations can reference up to 26 amplitude, high/low, and other measurement parameters, making it easy, for example, to normalise data with the amplitude measurement parameter.
Waveforms of computed results can be used for X-Y displays, FFT analysis, histograms, and other representations.
The Yokogawa SignalXplorer DL9000 Series of oscilloscopes includes models with bandwidths of 500 MHz, 1 GHz and 1.5 GHz, sampling rates of 2.5 and 5 GS/s per channel, and memory depths of 2.5 and 6.25 Mword per channel.
