2-2-7. X-Y Operation
The internal timebase of the OS-5060A are not utilized in X-Y operation ; deflection
in both the vertical and horizontal directions is via external signals.
Vertical channel I serves as the X-axis (horizontal) signal processor, so horizontal and
vertical axis have identical control facilities.
All of the V MODE, and trigger switches, as well as their associated controls
and connectros, are inoperative in the X-Y mode.
To set up OS-5060A for X-Y operation, proceed as follows ;
1. Push the X-Y switch (21)
CAUTION : Reduce the trace intensity,
lest the undeflected spot damage the
CRT phosphor.
2. Apply the vertical signal to the CH2 or Y IN connector (10), and the horizontal signal
to the CHI or X IN connector(9). Once the trace is deflected, restore normal
brightness.
3. Adjust the trace height with the CH2 VOLTS/DIV switch (14), and the trace width
with the CH1 VOLTS/DIV SWITCH (13). The PULL X5 MAG switches(15) and
(16) on the VARIABLE controls can be used if greater is necessary, so leave the
TIME VARIABLE control (25) knob pushed in.
4. Adjust the trace position vertically (Y axis) with the CH2 Vertical POSITION control
(18). Adjust the trace position horizontally (X axis) with the Horizontal POSITION
control (26) ; the CH1 Vertical POSTION control has no effect during X-Y operation.
5. The vertical (Y axis) signal can be inverted by pulling the CH2 Vertical POSITION
knob to activate the PULL CH2 INV switch (18).
