⚫ Bias Voltage
The oscilloscope provides the bias voltage adjustment function for active probes.
This function is used to adjust the signal under test that exceeds the input
dynamic range of the probe amplifier to an appropriate range to ensure the
integrity of the signal under test. Press Bias, rotate the multifunction knob
or use the numeric keypad to set the DC bias voltage.
⚫ Probe Information
Press About to view information about the probe currently connected, such as
the manufacturer, model, serial number, and the last calibration date.
⚫ Probe Calibration
Press Calibration to start zero calibration automatically for the probe.
Amplitude Unit
Select the amplitude display unit for the current channel. The available units are W, A,
V, and U. When the unit is changed, the unit related to the relevant functions of the
channel will change accordingly.
Press 1 → More → Unit, press Unit continuously or rotate the multifunction knob
to select a unit. You can also enable the touch screen to select the desired unit
with touch gestures. The default unit for the value is V.
Channel Delay
When using an oscilloscope for actual measurement, the transmission delay of the
probe cable may bring relatively greater errors (zero offset). MSO7000/DS7000
allows you to set a delay time for calibrating the zero offset of the corresponding
channel. Zero offset is defined as the offset of the crossing point of the waveform
and trigger level line relative to the trigger position, as shown in Figure 2-2.
