Cleverscope
Vsat probe
The CS1133 VSAT probe is used to measure the saturation voltage of a switching transistor. It uses a 30mA high
compliance current source to measure the transistor forward voltage while the voltage across the device is less than
the clip level. The clip level can be set to 3 ranges; approximately 15V, 1.5V and 150mV. Above the clip level the VSAT
probe is disconnected from the Unit Under Test (UUT). It is expected that the UUT will have a good deal more than
30mA flowing through it so this small additional current will not significantly change the saturation voltage. The
CS1110 is designed to work into a 50 ohm load. The CS1133 is rated for operation over the input voltage range of 0V
to +3.3kV. It can also withstand negative overshoot on the UUT down to -100V for short term transients.
