5-6.Measurement Application (GOS-6051/6031)
The oscilloscope has a cursor measurement system for making accurate,
direct-readout voltage, time and frequency measurements. The measurements
described in this section are examples of typical applications using this
measurement system. After becoming familiar with the controls, indicators,
and capabilities of the instrument, you can develop convenient methods to
make the special measurement for your own applications.
Proceed a measurement by using the cursor according to the following steps:
1. Press the [△V—△T, 1/△T—OFF] pushbuttons to turn on the cursor and
measurement readout.
2. Press the pushbutton to select the seven measurement function in the
sequence as below:
△ V —△T —1/△T—OFF
3. Press the [C1—C2 TRK] pushbutton to select C1(▼) cursor, C2(▽) cursor
and tracking cursor.
4. Rotate the VARIABLE control knob to position selected cursor. Press one
of the VARIABLE control knob to select FINE or COARSE cursor move
speed.
5. Read the measurement value on the screen. Typical measurement readouts
and applications are shown in Figure 5-16. The measurement values are
automatically controlled by the VOLTS/DIV and TIME/DIV control
settings.

Figure 5-16: Cursor Measurement
(a).Typical △V (Voltage difference) for AC
voltage.
When both CH1 and CH2 are turned on,
the measurement value of CH1(△V1).
(b).Typical △ T(Time difference) cursor
measurement for rise time.
Proceed rise-time or fall-time measurement
requiring some additional signal scaling by
using the graticale rise-time measurement
aids. Number 0%, 10, 90 and 100 are
etched near the left vertical gratical line.
Use the following steps as a guideline to in
making rise-time measurement:
(c).Typical 1/ △ T cursor function for
frequency measurement.
When the two cursors are superimposed at
two edge points of the one period
waveform by the [C1—C2 TRK] and
VARIABLE controls, the measurement
value is displayed in frequency units on the
upper side of the screen.
NOTE. When the VOLTS/DIV or the TIME/DIV controls are in
uncalibrated setting, the △ V and △ T measurement values will be
displayed with divisions.
When the vertical mode is set to the ADD mode, and the CH1 and CH2
VOLTS/DIV controls are set to different scales, the △V measurement
values will be displayed with divisions.
