Traces that have not yet been filled in the Spectrogram display are empty; there is no DATA
header for them. The file ends after the last non-empty trace.
Imagine that, at the point where a Spectrogram Meas Result is requested, the following screen is
showing:
For the purpose of this example, we have set the Average/Hold Number to 10, thus we have only
traces 0 thru 10. The Spectrogram was started at 02:28:08:700 pm on April 25, 2012 (that is, 700
ms after 2:28:08 pm), although the screen dump itself shows a duifferent time, as it was taken ten
minutes after the Spectrogram data. Trace 0 is showing a start time of 5.30 seconds, meaning 5.3
secodns after the Spectrogram started (trace 10 has a strat time of 0, as it was the first trace
taken but has now rolled up into the tenth trace slot).
The Meas Results file, when opened, shows the header data and ten traces of trace data. Below is
an extract from the result file for the above display. Note the start time of 20120425142808700
showing in the last row before the first DATA row, and the relative time of 5.299231048 showing
in the first DATA row:
