Section 4 — Measurement Types and their Uses80Long Time WaveformsLong time waveforms enable you to take a continuous recording over along time period (several hours, if required). This is useful for capturingtransients. Once you have started measuring, recordings are takencontinuously until your specified time period has elapsed, or you stop themeasurement manually. The length of time you can record for dependson the Equivalent Fmax. This determines the sample rate/lines ofresolution and the available memory remaining in the instrument.Measure Long Time WaveformsDuration is the total amount of time available for recording and isdisplayed in seconds. You can record for the full length of time availableor set a shorter time period. Your chosen time period is shown on top,while the available time is shown in brackets below this value.The Equivalent Fmax (which determines the maximum frequencydisplayed on your screen) will affect the available recording time. A highFmax reduces recording time, while a low Fmax increases the totalamount of time available for recording.While your instrument is recording, you can display the signal on yourscreen as a waveform. Alternatively, you can convert it to a spectraldisplay by pressing Display Type & Resolution and selecting yourpreferred display type.
