continuously to switch the current probe model. The probe models available
include P6205, P6241, P6243, P6245, P6246, P6247, P6248, P6249, P6250,
P6251, P5205, P5210, P670X, P671X and TCP202.
3. Ratio
Ratio displays the current probe ratio. If the probe currently connected
supports multiple probe ratios, you can use Ratio to select the desired probe
ratio. The probe ratios available are related to the model of the probe.
4. Front-End
Front-End displays the type of the front end of the probe currently connected.
If the probe currently connected is P670X, P671X or TCP202, this menu item is
not provided.
In addition, the oscilloscope supports the probe calibration and bias voltage
adjustment of some Tek probes, including P6241, P6245, P6246, P6247, P6248,
P6249, P6250 and P6251. For these probes, Probe-Cal and Bias Voltage are
provided in the probe submenu.
5. Probe-Cal
Press Probe-Cal and ground the probe input terminal according to the probe
calibration prompt message. Press OK and the oscilloscope starts calibrating the
probe.
6. Bias Voltage
Press Bias Voltage and turn the multi-function knob to adjust the DC bias
voltage.
Note: The adjustable range of the DC bias voltage is related to the probe model
and probe ratio (only for models that supports multiple probe ratios). For the
details, please refer to the technical specifications of the corresponding probe.
