In the right menu, select
Coupling
as
DC
. Both DC and AC components of
the signal are passed.
(3)
In the right menu, select
Coupling
as
AC
. The direct current component of
the signal is blocked.
2.
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)
In the right menu, select
Inverted
as
ON
, the waveform is inverted. Push
again to switch to
OFF,
the waveform goes back to its original one.
3.
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 "
How to Set
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 to1X.
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)
In the right menu, select
Probe
. In the left menu, turn the
M
knob to set it as
10X
.
4.
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 1
Ω resistor, the operation steps are shown as follows:
(1)
Push the
CH1
button to show CH1 SETUP menu.
(2)
In the right menu, set
MeasCurr
as
Yes
, the A/V radio menu will appear
below. Select it; turn the
M
knob to set the Amps/Volts ratio. Amps/Volts
ratio = 1/Resistor value. Here the A/V radio should be set to 1.
Use Mathematical Manipulation Function
The
Mathematical Manipulation
function is
used to show the results of the addition,
multiplication, division and subtraction operations between two channels, or the FFT
operation for a channel
.
