On the 190 series what is the difference between Scope Record and Trend Plot?
The TrendPlot feature of the 190-series makes the instrument act as a paperless recorder that will collect a series of parameter measurements over time and will show the result as a graph, a trend-line, on screen. The measurements themselves can either be made using the Multimeter or can be any of the measurements that the oscilloscope can make on the waveform, like risetime- or dutycycle-measurements. The resulting TrendPlot graph will thus show the risetime or the dutycycle as it changes over a longer period of time. This is most useful for instance when studying the change of individual parameters over time or the influence of environmental changes like temperature over time. The ScopeRecord mode on the other hand is a genuine oscilloscope mode: the applied input voltage is registered over time and the resulting waveform is stored in a long memory record. In ScopeRecord mode, still the full bandwidth of the oscilloscope applies and so this mode can be used to see amplitude changes o
