(2) Select
Coupling
in the bottom menu.
(3) Select
DC
in the right menu. Both DC and AC components of the signal are
passed.
(4) Select
AC
in the right menu. The direct current component of the signal is
blocked.
2. To adjust the probe attenuation
For correct measurements, the attenuation coefficient settings in the operating
menu of the Channel should always match what is on the probe (see "
the Probe Attenuation Coefficient
" on P11). If the attenuation coefficient of the
probe is 1:1, the menu setting of the input channel should be set to X1.
Take the Channel 1 as an example, the attenuation coefficient of the probe is
10:1, the operation steps are shown as follows:
(1) Push the
CH1
button to show the CH1 SETUP menu.
(2) Select
Probe
in the bottom menu. Select
Attenu
in the right menu, select
10X
in the left menu.
3. To measure current by probing the voltage drop across a resistor
Take the Channel 1 as an example, if you are measuring current by probing the
voltage drop across a
1Ω resistor, the operation steps are shown as follows:
(1) Push the
CH1
button to show CH1 SETUP menu.
(2) Select
Probe
in the bottom menu. In the right menu, set
MeasCurr
as
YES
,
the A/V radio menu will appear below. Select it; Click
or
to set the
Amps/Volts ratio. Amps/Volts ratio = 1/Resistor value. Here the A/V radio
should be set to 1.
4. To invert a waveform
Waveform inverted: the displayed signal is turned 180 degrees against the
phase of the earth potential.
Taking the Channel 1 for example, the operation steps are shown as follows:
(1) Push the
CH1
button to show the CH1 SETUP menu.
(2) Select
Inverted
in the bottom menu, switch to
ON.
the waveform is inverted.
Push again to switch to
OFF,
the waveform goes back to its original one.
5. To set bandwidth limit
When high frequency components of a waveform are not important to its
analysis, the bandwidth limit control can be used to reject frequencies above 20
MHz.
Taking the Channel 1 for example, the operation steps are shown as below:
(1) Push the
CH1
button to show CH1 SETUP menu.
(2) Select
Limit
in the bottom menu.
