Xt, X10, X50 Magnify Switch
The
Xl, XlO, X50
Magnify switch selects the amount of hori-
zontal magnification
(Xl, XlO, X50).
The magnified trace is
that part of the unmagnified trace registered around the cen-
tre vertical graticule line.
In Store mode, with
M
cursors selected, operation of the
horizontal magnify switch will also magnify the distance be-
tween the cursors as they are attached to the waveform(s).
The
Xl, XlO, X50
sweep magnification switch also functions
on reference waveform displays and provides for a horizontal
expansion of 10 and
50
times.

Variable SEC/DIV (VAR) control
The Variable SEC/DIV (VAR) control continuously varies the
uncalibrated sweep time per division in the Non-Store posi-
tion up to at least 2.5 times the calibrated time per division,
set by the SEC/DIV switch.
The VAR SEC/DIV is not operational in Store mode.
Pushing the lower switch of the Variable seconds per divi-
sion controls sets the SEC/DIV switch to the UNCAL position
and increases the sweep time per division. Pushing the upper
switch of the variable time per division controls reduces the
sweep time perdivision until it has reached the calibrated
position.
