(25) H POSITION (Real Time mode only)
The control knob enables a horizontal position shift of the signals. In
combination with MAG the function makes it possible to shift any part of the
signal on the screen.
In X-Y mode, the control knob are used for the X deflection.
(26) TIME/DIV-VAR– Control knobs
Turning the knob clockwise to reduce the deflection coefficient in a 1-2-5
sequence and turning it in the opposite direction (CCW) to increase. The
time coefficient(s) will be displayed in the readout.
In the REAL TIME mode, the time deflection coefficients between 0.5s/DIV
and 0.2μs/DIV can be chosen in 1-2-5 sequence, if the MAG function is not
activated.
In the STORAGE mode, the sampling method is changed automatically by
the TIME/DIV range.
Equivalent sampling (EQU): 0.2μs/DIV to 0.5μs/DIV.
Only a repetitive signal can be stored.
Normal sampling (SMPL): 1μs/DIV to 0.1s/DIV.
Single shot and repetitive signal can be stored.
Roll mode: 0.2s/DIV to 100s/DIV.
For observing flickering low-speed signals.
VAR (Real Time mode only)
Pressing the pushbutton to select the TIME/DIV control knob function
between time base switch and vernier (variable). In the Real Time mode,
after switching on the VAR, the time deflection coefficient is still calibrated
until further adjustments are made. Turn the TIME/DIV control knob counter
clockwise to increase the time deflection coefficient (reduce the deflection
speed) and the deflection coefficient becomes uncalibrated. The current
setting is displayed by the “>” symbol in the readout.

(27) X-Y
Pressing the pushbutton when using the instrument as an X-Y oscilloscope.
The time deflection coefficient is replaced by the “X-Y” symbol in the
readout.
In this mode, the X (horizontal) signal is connected to the input of CH1; the
Y (vertical) signal is applied to the input of CH2 and has a deflection range
from less than 1mV to 20V/DIV at a reduced band-width of 500kHz (Real
Time mode).
In the Storage mode, the X-Y operation is same as the REAL TIME mode.
The storage waveform bandwidth of both X and Y signal are up to
50MHz/30MHz.
(28) ×1/MAG
Pressing the pushbutton the select the sweep time between ×1 (normal) and
MAG (magnify). If the MAG function, the signal display will be expanded
and consequently only a part of the signal curve is visible. The interesting
part of the signal can be made visible with the aid of the H POSITION
control in the REAL TIME mode.
(29) MAG FUNCTION
Ч5-Ч10-Ч20 MAG
When MAG has been done, the displayed waveform will be expanded to the
right and left with the center of the CRT. The magnification ratio can be
selected from among three stage of Ч5-Ч10-Ч20 MAG by pressing this
pushbutton.
ALT MAG
Pressing the pushbutton, the primary sweep waveform along with the
magnified sweep waveform. The magnified can be displayed
simultaneously using the ALT-MAG function. The magnified sweep
waveform appears 3 divisions below the primary sweep waveform.
