(2) Cursor Measurement Procedures
1)
Apply the signal to the input connector. Select the chan-
nel to be used w i t h the V E R T I C A L MODE, and adjust
each control for the normal s w e e p display. Adjust the
V O L T S / D I V and S W E E P T I M E / D I V to obtain proper
waveform display. Set the V A R I A B L E used channel and
S W E E P T I M E to C A L condition.
2)
Select the VAT cursor mode with the C U R S O R S .
3 )
Adjust the AREF cursor to the left of the points to be
measured and the ^ c u r s o r to the right.
4)
Measured value is displayed following VAT in the up-
per right of the C R T .

12. RELATIVE MEASUREMENT
If the frequency and amplitude of the reference signal are
k n o w n , voltage and frequency of an unknown signal can
be measured without use of the V O L T S / D I V and S W E E P
TIME/DIV controls. This measurement uses the relative unit
determined by the reference signal for measurement of an
unknown signal.

* Vertical Sensitivity
Setting of the relative vertical sensitivity using a reference
signal amplitude
1)
Apply the reference signal to the input connector. A d -
just each control for normal s w e e p display. Adjust the
V O L T S / D I V and V A R I A B L E controls accurately so that
the signal amplitude coincides with a f e w divisions of
the graduation line.
Do not change V A R I A B L E setting after the above ad-
justment.
2)
Divide the voltage amplitude of the reference signal by
the
product of
the
V O L T S / D I V setting given in item 1) above.

3)
Discontinue applying the reference signal and apply the
unknown signal to the input connector. Adjust the
V O L T S / D I V to obtain proper w a v e f o r m observation.
Measure the waveform amplitude, and calculate the vol-
tage of the unknown
equation:
