mode. As the ranges are changed, the cursor will
remain at the same position as the previous range.
3. If the instrument is setup in the dual cursor
mode, cursor 1 can also be adjusted; however, it
will be placed back at the "0" distance marker
whenever a new range is selected.
2.3.2 Distance Between Cursors
Distance readout format may be selected in the setup menu
as either single distance cursor or dual distance cursor.
Single Cursor Operation
Single cursor operation uses a single distance cursor to
display the distance to fault. All measurements are refer-
enced from the zero distance marker and the front panel
cursor keys control cursor movement. Remember that the
distance measurement is from the transmitted pulse, to the
cursor. Accuracy of the distance reading is dependent on
the placement of the cursor and an accurate VOP.
Dual Cursor Operation
When a test is initiated, the independent cursors are used
to measure the distance to a fault or to the end of the cable.
The cursors are interchangeable; but, to reduce confusion,
use the 1st cursor to mark the point you are measuring
from and the 2nd cursor to mark the point you are measur-
ing to. The cursors will retain their accuracy and resolu-
tion regardless of distance or horizontal zoom settings.
Model 3300's unique dual independent cursors allows you
to place cursors at, and measure to (or between) ANY TWO
POINTS on the waveform. The distance displayed will au-
tomatically adjust with the movement of the cursors. The
front panel cursor keys control Cursor 2 and a menu selec-
tion controls Cursor 1.
DISTANCE BETWEEN CURSORS is automatically cal-
