Offset Cal
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 may occur on the zero-cross voltage of the channel, which will affect the
measurement results of the vertical parameters. MSO7000/DS7000 allows you to set
an offset calibration voltage for calibrating the zero point of the corresponding
channel, so as to improve the accuracy of the measurement results.
Note: If the zero-cross voltage of the channel has a larger amplitude offset that
exceeds the adjustable null range, please perform self-calibration for the
instrument to ensure the measurement accuracy. For details, refer to
descriptions in "Self-calibration".
Press 1  More  Offset Cal, rotate the multifunction knob or use the
numeric keypad to set the offset calibration value.
Channel Label
The instrument uses the channel number to mark the corresponding channel by
default. For ease of use, you can also set a label for each channel. For example,
" ".
Press 1  More  Label to enter the label setting menu. You can use the built-in
label or manually input a label. Three input methods are available for you to input a
label name, including Chinese, English, and Traditional Chinese.
The label setting menu includes the following menu items.
 Press Display to turn on or off the display of the channel label. If it is enabled,
the label will be displayed at the left side of the waveform. When on, CH1 is, by
default, displayed to be the channel label.
 Press Library to select the preset labels such as CH1, ACK, ADDR, BIT, CLK, CS,
DATA, IN, MISO, MOSI, OUT, RX and TX.
 Press Label and the label editing interface is automatically displayed as shown in
Figure 2-3. You can input the label manually. For the label input method, refer to
"To Create a Folder".
