6. METHOD FOR CONNECTING SIGNALS
(2) When observing two waveforms
Observation of two waveforms can be made easily by
setting the MODE switch of vertical axis to ALT or CHOP.
When observing two waveforms of high repetition frequen
cies set the MODE switch to ALT and, in the case of low
frequencies, set it to CHOP.
When measuring the phase difference, measure after effect
ing synchronization with leading phase signal.
The first step of measurement is introducing the signal
desired to measure to the oscilloscope properly. Do it with
utmost care.
(1) When using a probe
Use the attached probe, AT-10 AJ 1.5, when measuring a
high frequency wave with high accuracy.
It should be noted, however, that since the input signal is
attenuated by this probe to 1/10 before it is input to the
oscilloscope the use of the probe is disadvantageous for low
level signals, and that at the same time the measuring range
is extended by that amount for high level signals.
< CAUTIONS >
o Do not apply a signal which exceed 400V (DC + peak
AC at 1 kHz).
o Bring the grounding point of the earth lead wire of the
probe close to the point to be measured when measur
ing a rapid rising signal or a high frequency signal. Long
earth lead wire may cause waveform distortions such as
ringing and overshoot.
