Trace
+
Card
begins the process used to save trace data, limit-line tables, or amplitude-
correction factors on the memory card. Pressing Trace
+
Card
accesses
a
softkey
menu that allows you to select the trace to be saved (trace A,
trace B, or trace C) and accesses the LIMIT LINES and AMP COR
softkeys.
To save a trace, press TRACE A , TRACE B , or TRACE C , use the numeric
keypad to enter a trace register number, and press
@!iE].
To save limit-line
tables or amplitude-correction factors, press LIMIT LINES or AMP COR , use
the numeric keypad to enter a trace register number, and press
@iEEQ
If
windows are being used, only the trace of the active window will be saved.
If you want the file name of the stored data to contain a prefix, press
Change Prefix to enter a prefix before storing the data. If the trace data
was stored using a prefix, the file name is t(prefix)-(register number). If no
prefix was available, the data is stored under
t-(register
number). File names
for limit-line tables and amplitude-correction factors are treated the same way
as file names for trace data, except “1” or “a” is used instead of “t.” If a screen
title is present, it is saved with the trace data. The time and date that the data
was stored is appended to the screen title.
When comparing a trace displayed in view mode with a recalled trace, it is
possible to over-write the displayed trace by recalling the trace data. This can
happen because the instrument state is saved (and recalled) with the trace
data.
For example, if you save trace A when it is in clear-write mode, place trace A
in view mode, then recall the trace data into trace B, trace B will be placed
in view mode, but the trace mode of trace A is changed to clear-write mode
(since the trace mode of trace A was clear-write when it was saved). To avoid
this problem, we change the trace mode of the traces to view or blank mode
before saving the trace data.
