This wonderful feature is reminiscent
of the days of the old paper strip chart recorders. There have been
many improvements in instrumentation since those days, but the strip
chart concept still offers the best graphic depiction of amplitude
over time. The Strip Chart function can record amplitude over time
from 1 minute to 8 hours, plus a continuous recording mode. The finished
chart can be saved to a tab-delimited ASCII character file and transferred
to a PC for further display and manipulation, using Ivie's "IvieXLS" graphing
software or any other compatible means.
Weighting and Filtering - All
of the SPL detectors can be applied to Strip Chart as can the weighting
and filtering.
Chart Time - Chart Time settings
allow the user to select the amount of time it takes the strip chart “pen” to
trace a line from the far right of the display to the far left. Minimum
time is 1 minute, maximum is 8 hours, and there is “continuous” setting
as well.
Set dB Scale - As in the RTA
display, this function allows the user to set the amplitude resolution
of the display. |
