X-Y Mode; Waveform Magnification - Tenma 72-6802 User Manual

X-Y Mode

Background
The X‐Y mode compares the amplitude of two
signals (CH1 and CH2), one as X‐axis (CH1) and
the other as Y‐axis (CH2). The X‐Y mode is useful
for measuring the phase difference of two signals,
video color patterns, and frequency response.
Steps
1. Make sure both CH1 and CH2
waveforms appear on the
display. For details, see page30.
2. Move the TIME/DIV knob to the
X‐Y position.
3. The CH1 and CH2 signals appear in the X‐Y
mode and the X‐Y indicator in the LCD display
( X‐Y ) turns on.
4. To adjust the X‐axis position and
deflection, use the horizontal
POSITION knob (position) and
CH1 VOLTS/DIV knob
(deflection).

5. To adjust the Y‐axis position and
deflection, use the CH2 vertical
POSITION knob (position) and
CH2 VOLTS/DIV knob
(deflection).
The oscilloscope can magnify the waveform by ten
times in the horizontal direction. The
magnification is useful for observing complex
signals.
1. Make sure the waveform is shown on the
display.
2. Press the ×10 MAG switch. The
waveform becomes magnified
by ten times in the horizontal
direction.
