Tek Probe 
 
1.  Probe Type 
Probe Type displays “Tek Probe”; for example, when Tek (Tektronix) P6245 
probe is connected.  
Note: When a Tek probe is used, the oscilloscope sets the channel input 
impedance automatically according to the model of the probe actually 
connected.  
 
2.  Mode 
Press Mode and turn the multi-function knob   to select the probe model 
corresponding to the probe actually connected. You can press this softkey 
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.
