VERT MODE
DC: All components of the input
signal are passed to the Vertical
Amplifier.
Dual-purpose switch that, when
pulled out, limits the bandwidth of
the complete Vertical Deflection
System to approximately 20 MHz,
or when pressed causes signal pre-
sent in A Trigger Generator circuit
to be displayed on the CRT.
Pushbutton switch that inverts the
Channel 2 display.
Selects the vertical mode of opera-
tion.
CH 1: Displays Channel 1 only.
ALT: Dual-trace display of signals
on both channels. Display is
switched between channels at
the end of each sweep.
ADD: Signals applied to the CH 1
OR X and CH 2 OR Y connect-
ors are algebraically added and
the sum is displayed on the
CRT. The INVERT switch in
Channel 2 allows the display to
be CH 1 + CH 2 or CH 1 - CH
2.
CHOP: Dual-trace display of signals
on both channels. Display is
switched between channels at an
approximate repetition rate of
250 kHz.
CH 2 OR X-Y: Displays Channel 2
only. Must be pushed when op-
erating in X-Y mode.
A and B Triggering {both where applicable)
COUPLING
2-4
Determines the method used to
couple signal to input of trigger
circuits.
AC: Rejects DC and attenuates
signals below about 60 Hz. Ac-
cepts signals above about 60 Hz.
LF REJ: Rejects DC and attenuates
signals below about 50 kHz. Ac-
cepts signals above about
50 kHz.
SOURCE
SLOPE
LEVEL
HF R EJ: Accepts signals between
60 Hz and 50 kHz. Rejects DC •-·•
and attenuates all signals outside ..,
the above range.
DC: Accepts all trigger signals from
DC to 100 MHz or greater.
Selects source of trigger signal.
NORM: Internal trigger signal ob-
tained from Vertical Deflection
System. Actual source is
signal(s) displayed on CRT.
CH 1: A sample of the signal
connected to the CH 1 OR X
input connector is used as a
trigger signal.
CH 2: A sample of the signal
connected to the CH 2 OR Y
input connector is used as a
trigger signal.
EXT: Trigger signal is obtained
from signal connected to the
External Trigger Input con-
nector.
EXT --:--10 (A trigger circuit only):
External trigger signal is attenu-
ated by a factor of 10.
STARTS AFTER DELAY (B trig-
ger circuit only): B sweep starts
immediately after the delay time
selected by the DELAY-TIME
POSITION dial and the DELAY-
TIME switch.
LINE (A trigger circuit only):
Trigger signal is obtained from a
sample of the line voltage
applied to the instrument.
Selects the slope of the trigger
signal which starts the sweep.
+: Sweep can be triggered from the
positive-going portion of the
trigger signal.
-: Sweep can be triggered from the
negative-going portion of the
trigger signal.
Selects the amplitude point on the
trigger signal at which the sweep is
triggered.
