ADD will be difference in amplitude of the two signs. (EX: 4.2 Div - 1.2 Div = 3.0 Div.). When input sign has
phase difference of 180° two signs become sum of amplitude.
2.2.8 X-Y Operation
The internal timebase of the PeakTech 2020 GN / PeakTech 2030 KT are not utilized in X-Y Operation;
deflection in both the vertical and horizontal directions is via external signals. Vertical channel 1 serves as
the X-axis (horizontal) signal processor, so horizontal and vertical axes have identical control facilities.
All of the V MODE, and trigger switches, as sell as thire associated controls and connectors, are inoperative
in the X-Y mode.
To set up the PeakTech 2020 GN / PeakTech 2030 KT for X-Y operation, proceed as follows:
1. Turn the TIME/DIV switch (15) fully clockwise to its X-Y positions.
Caution: Reduce the trace intensity, lest the undelected spot damage the CRT phosphor.
2. Apply the vertical signal to the CH 2 or Y IN connector (22), and the horizontal signal to the CH 1 or
X IN connector (24). Once the trace is deflected, restore normal brightness.
3. Adjust the trace height with the CH 2 VOLTS/DIV switch (23) and the trace width with the CH 1
VOLTS/DIV SWITCH (27). The x5 MAG switch (3) on the VARIABLE controls can be used if greater
is necessary, so leave the VARIABLE control (27) knob set CAL.
4. Adjust the trace position vertically (Y-axis) with the CH2 Vertical POSITION control (7). Adjust the
trace position horizontally (X-axis) with the Horizontal POSITION control (10); the CH 1 Vertical
POSITION control has no effect during X-Y operation.
5. Vertical (Y-axis) sign may change the phase by 180° setting CH 2 INV switch.
2.2.9 Component Test Operation (Only PeakTech 2030 KT)
The component test board delivers a sine voltage (60 Hz) which is applied across the component under test.
The sine voltage across the test object is used for the horizontal deflection (V) and voltage-drop (current
through the test object) is used for vertical deflection (I) of the oscilloscope.
By this V-I characteristic curve, the good or fault of component is measured.
To set up the PeakTech 2030 KT for component test operation, proceed as follows:
1. Push the component test switch.
Then the horizontal bar graph of 8 div. is displayed on the screen. The position of bar graph is
controlled with CH2 V-POSITION (7) and H-POSITION (10).
2. Connect the component test input (36) and GND (37) to both terminals of component with DMM
Probe. Then V-I characteristic curve is displayed on the screen (see figure 2-6).
CAUTION!
Using the component test function, don’t apply the signal to CH 1 and CH2 input because the
oscilloscope doesn’t operate in the component test mode.
Don’t push x10 switch because the bar will be fatted. Don’t test the live circuit (operating the power
signal) component.
