If a trace is memorized as trace n, whatever trace was previously memorized as trace n will be
overwritten and cannot be retrieved. However, the title of the memorized trace is not affected
by the memorization of a new trace.
[ DISPLAY TRACE N]
Menu F1-1: Presents a prompt to enter the number of the trace in memory that it is desired to
examine. When a UNITS key is pressed, the specified memorized trace will replace the entry
channel measurement trace. The memorized trace title will replace the title of the entry chan-
nel (when the channel title has been turned on).
[
CLEAR TRACE N]
Menu F1-1: Clears a memorized trace. When a memorized trace is cleared, it is replaced with a
0 dBm trace so that it will have no effect if ratio’ed with a measurement trace. The title of the
memorized trace will also be cleared.
When a number is entered, the memorized trace is cleared and the entry area of the display will
indicate that the operation was completed.
[ CLR ALL TRACES]
Menu F1-1: Clears all of the memorized traces. When a memorized trace is cleared, it is
replaced with a 0 dBm trace so that it will have no effect if ratio’ed with a measurement trace.
The titles of the memorized trace will also be cleared. (See the Trace Memory description on
page 2-19).
When [ CLR ALL TRACES ] is pressed, the entry area of the display will show the prompt:
CONFIRM TO CLEAR
The softkey menu will present the option of either clearing all traces or to abort the clearing
function. When [
CLR ALL TRACES ] is pressed a second time, all memorized traces will be
cleared. The entry area of the display will indicate that the traces have been cleared and the
instrument will return to menu F1.
NOTE:
A trace cannot be restored once it is cleared.
NOTE:
This action cannot be reversed once accomplished. Cleared traces cannot
be restored.
