Display modes

The CH1 - CH2 - ALT - CHOP vertical modes are selected using vertical sensitivity
switches (5) (11) and the timebase switch (15).

Display channel CH1 only:
Set the CH1 switch (5) to one of the twelve positions from 20 V to
5 mV/div, and set the CH2 switch (11) to the OFF position.
Display channel CH2 only:
Set the CH2 switch (11) to one of the twelve positions from 20 V to
5 mV/div, and set the CH1 switch (5) to the OFF position.
Display channels CH1 and CH2 in alternate mode:
Set the CH1 (5) and CH2 (11) switches to one of the 12 positions from
20 V to 5mV/div, and the timebase switch (15) to one of the 13 positions
between 0.5 ms and 50 ns.
Display channels CH1 and CH2 in CHOP mode:
In a single scan, the channel changes from CH1 to CH2 at the chopping
frequency (about 200 kHz).
Set the CH1 (5) and CH2 (11) switches to one of the 12 positions from
20 V to 5 mV/div. and the timebase switch (15) to one of the 8 positions
between 200 ms and 1 ms.
Display channels CH1+CH2:
The difference between channels CH1-CH2 is displayed if -CH2 mode is
active.
To obtain this mode, set the CH1 (5) and CH2 (11) sensitivity switches to
one of the 12 positions 20 V to 5 mV and press on the ADD key.
Display channels CH1 and CH2 in orthogonal coordinates (CH1 in X,
CH2 in Y):
The timebase is disabled, vertical framing is done using the POSITION
control (10), and horizontal framing is done using the POSITION control
(6).
This mode is obtained by setting switch (15) to one of the 3 XY positions.
Inversion of channel CH2:
Press on key (9) to invert CH2.
Sweep speed: 21 positions from 50 ns to 200 ms/div.
XY: When the switch is on the XY position, channels CH1 and CH2 are
displayed in orthogonal coordinates (CH1 in X, CH2 in Y); the timebase
is disabled.
Horizontal expansion (x10):
Horizontal expansion magnifies some details and reaches 10 ns/div.
(control disabled at 50 ns/div.).
