Slide switch; in combination with the TIME/DIV
switch selects the time coefficients. In A&B-mode
the display is chopped in position ms and
alternated in position Us.
Slide switch; allows increase of the horizontal
deflection by a factor of 5.
In combination with the Us/ms switch, selects
the time coefficients from 0.5 Us/DIV to
200 ms/DIV in a 1-2-5 sequence.
In the position X via A, horizontal deflection is
determined by the channel A input signal
(bandwidth < 2 MHz).
CAUTION: Extended high intensity may
damage CRT especially with a stationary or
slow-moving spot.
Slide switch; triggering is effected on the signal
derived from channel A or B, depending on the
switch position.
Slide switch; enables triggering on the positive-
going (+) or negative-going (—) slope of the input
signal.
Slide switch; the time base can trigger either on a
signal derived from channel A or B, or on a signal
applied to BNC connector EXT.
Slide switch; normal triggering. DC component
of the trigger signal is blocked.
TV line or TV frame synchronisation is obtained.
(Frame in position ms, and line in position ps).
BNC socket for external trigger input.
