TIP
The oscilloscope auto-recognizes certain probes with a fixed attenuation ratio. After that, the
probe ratio will also be auto recognized to save you from configuring it manually.
Skew
The difference in the delays between the probes, known as skew, can cause great
cable-delay errors in measurement results. To eliminate this problem, this series
oscilloscope provides the deskew function. Click or tap the Skew input field to set the
delay time with the pop-up numeric keypad. You can also use the corresponding
numeric keypad to set the value. The value ranges from -100.00 ns to 100.00 ns, and
the default is 0.00 s.
Bias
The oscilloscope provides offset adjustment function for active probes. This function
is used to adjust the signal under test which is outside the probe amplifier input
range to a proper range so as to ensure the signal integrity. When working with the
RP7000/PVA7000 series probe, you can click or tap the input field of Bias to set the
bias voltage of the probe.
Probe Information
After the oscilloscope recognizes the probe automatically, you can view information
about the currently connected probe in the probe menu, such as the vendor, model,
serial number, and the last calibration time.
Go Back to the Vertical Menu
In the
Probe setting menu, click or tap Vertical to go back to the Vertical menu.
5.9 To Specify the Amplitude Unit
Click or tap the channel status label at the bottom of the screen, and then the
Vertical menu is displayed. Click or tap the Unit drop-down button to select W, A, V,
or U. The default unit is V.
Changing the amplitude unit also changes the units of the functions related to the
channel accordingly.
5.10 To Adjust Bias
When you use an oscilloscope to make actual measurements, a small offset that arises
from the temperature drift of the component or external environment disturbance
