Long Time Waveforms
Long time waveforms enable you to take a continuous recording over a
long time period (several hours, if required). This is useful for capturing
transients. Once you have started measuring, recordings are taken
continuously until your specified time period has elapsed, or you stop the
measurement manually. The length of time you can record for depends
on the Equivalent Fmax. This determines the sample rate/lines of
resolution and the available memory remaining in the instrument.
Measure Long Time Waveforms
Duration is the total amount of time available for recording and is
displayed in seconds. You can record for the full length of time available
or 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 frequency
displayed on your screen) will affect the available recording time. A high
Fmax reduces recording time, while a low Fmax increases the total
amount of time available for recording.
While your instrument is recording, you can display the signal on your
screen as a waveform. Alternatively, you can convert it to a spectral
display by pressing Display Type & Resolution and selecting your
preferred display type.
