Choosing a probe with the correct bandwidth enables you to use your scope to its full potential.

CMMR is a measure of how well a differential probe will reject signals common to both test points, leaving the desired signal to be displayed by the scope.
Since the input of every oscilloscope is different our probes have a compensation adjustment so the capacitance of the probe can be adjusted to match the capacitance of the scope input. The compensation range is the range of adjustment available. Matching probe and scope capacitance is important to prevent waveform distortion.
Select a probe that is at least the same bandwidth as the oscilloscope you intend to use; however, for optimum performance, select a probe with two times the bandwidth of your test instrument.
Passive X10 probes allow you to read a signal 10 times the amplitude of that viewed with a X1 probe. Example: an eight-division graticule on 5V/Div setting would display a 40 volt peak-to-peak signal using the X1 setting. You can view a 400 volt signal using the X10 setting.
Readout is an activator pin that protrudes out of the BNC connector of an X10 or X100 probe that completes a circuit. There are contacts around the BNC connector on the front of the oscilloscope and the attenuation is automatically set. If your scope does not have contacts around the BNC connector, it does not need this feature.
Impedance is a measure of how much a signal will be restricted. In general, it is best to have high resistance and low capacitance to ensure signal quality, accuracy of tests, and to ensure the probe doesn''t load down the circuit under test.
This specification provides you with the maximum voltage between the inputs the differential probe can be subjected to. This is important because the maximum voltage should never be exceeded.
You will receive one differential probe, 2 probe tips, and 2 retractable sprung probes for accessing small wires for measurements.
With 20 MHz bandwidth, a switchable attenuation of 20:1, and 200:1 (part no. ADF25), you can measure high-voltage circuits, motor speed controls, power supply design, and high-power electronic converters.
Yes, TPI oscilloscope probes can be used with most major brands of scopes.

Solid, does the job

I got the P250 mostly for use with vacuum tube radios, where I encounter somewhat high voltages at high impedances. The high input impedance doesn't load the circuit as much as a x10 probe. The lack of a switch means one less thing to fail or to set wrong. The probe and provided accessories are solid, sturdy, and well-finished.
