(3) INTEN—Control knob (REAL TIME Mode only)
The control knob is used for adjusting the traces intensity in the real time
mode. Turning the knob clockwise to increase the intensity while turning it
counterclockwise to decrease the intensity.
(4) FOCUS
The control knob effects both the trace and the readout sharply.
(5) CAL
The terminal provides a reference signal of 0.5Vp-p at 1kHz for probe
adjustment.
(6) Ground Socket—Banana Socket galvanically connected to safety earth
This socket can be used a reference potential connection for DC and low
frequency signal measurement purpose.
(7) TEXT/ILLUM—Control knob with a double function.
The pushbutton is for selecting the text readout intensity function or scale
illumination function, and indicates the letter “TEXT” or “ILLUM” in the
readout. Press the pushbutton for the following sequences:
“TEXT” — “ILLUM” — “TEXT”
The TEXT/ILLUM function is associated the VARIABLE (9) control knob.
Turning the knob clockwise to increase the text intensity or scale
illumination, while turning the knob counterclockwise to decrease it.
Pressing the knob to switch the TEXT/ILLUM on or off.
In the STORAGE mode, the brightness of the waveform on the screen can be
controlled by the “TEXT”.
(8) CURSORS MEASUREMENT FUNCTION
There are two pushbutton and associated the VARIABLE (9) control knob.
When the pushbutton is pressed, the three measurement functions will be
selected in the sequence as follows:
△V—△T—1/△T—OFF

△V: Two horizontal cursors appear. The voltage between the two cursors is
calculated according to the setting of VOLTS/DIV, and displayed with
△V on the upper side of the CRT.
Single channel mode (CH1 or CH2):
The △V measuring result is automatically related to the deflection
coefficient of the active channel. The readout displays “△V1…” or
“△V2…”.
Dual channel mode:
The cursor lines must be set on the CH1 or CH2 signal. As the
deflection coefficients may be different, it will be required to select
between the deflection coefficient of CH1 and CH2.
ADD mode:
In ADD (addition) mode, normally two input signals are displayed as
one signal (sum or difference). As the result can only be determined if
both (calibrated) deflection coefficients are equal, the readout indicates
“ △ V…” without any additional channel information. Different
deflection coefficient settings or uncalibrated deflection coefficients
are indicated in the readout as “△V=…DIV”.
X-Y mode:
In the X-Y mode, the instrument is automatically set to △ V
measurement. The deflection coefficient selected for each channel may
be different, thus as in DUAL mode the △V cursor measurement
requires a channel selection. Under channel 1 (X signal) measuring
condition the cursor lines are displayed as vertical lines and the readout
displays “△VX…”. Pressing the pushbutton, select channel 2 (Y
signal) measuring, then the cursor lines are displayed as horizontal
lines and the readout indicates “△VY…”.
△T: Two vertical cursors appear. The time between the two cursors is
calculated according to the setting of TIME/DIV, and displayed with
