To store a waveform, scroll through the menu items until
STORE is highlighted. SUPER-STORE will prompt the
operator to select a memory location.
NOTE: If a memory location is selected which
already has a stored waveform, the user will be
prompted to overwrite the existing waveform or
cancel the store. Memory locations do not have
to be “cleared” to use.
The user can clear all waveforms in memory by
using the “clear waveform” function.
To choose a previously stored waveform, scroll through
the menu until RECALL is highlighted. A memory se-
lection list will appear allowing the user to select the
desired memory location. Choose any of the stored
waveforms by scrolling to the desired number. When
the desired location number is highlighted, press
*
to
select the stored waveform to be displayed with the
live waveform. All instrument functions will operate
normally.
SUPER-STORE will optimize the distance and resolution
of a stored waveform based on the pulse width of the
test. The following table describes minimum distances
versus pulse width of a stored waveform.

2.3.10 Noise Filter / Powered Cable
Testing a cable that has power or a signal present is
possible, although for safety reasons, it is not recom-
mended.
WARNING
: The Model 1205CXA’s input is pro-
tected. The instrument features a POWERED
CABLE WARNING which appears in the mes-
sage center when a cable with power present
is attached. However, for safety reasons, it is
recommended that the Model 1205CXA
NOT
be connected to cable where a signal or power
is present.
If you must test a cable with power present, the Model
1205CXA features NOISE FILTERS. If the Model
1205CXA is connected to a cable with power present,
the microprocessor automatically filters out the power
