5. Signal Adjustment

Lissajous
Oscilloscope
CH2 CH1
Move the detector head in the azimuth direction shown in the figure, and then adjust so that the Lissajous is
within the range of the specified values over the entire length.
<Specified values>
A/B signal output type ...... Output format A : Amplitude 0.9 Vp-p to 1.8 Vp-p
Analog output type ........... Output format H : Amplitude 0.3 Vp-p to 0.6 Vp-p
Azimuth direction
• For output format A, the center of the Lissajous' figure is 0 V. For output format F, G, and H, the center of
the Lissajous' figure is 2.5 V.
• Turn off the interface unit before connecting or disconnecting the oscilloscope.
