In the process of using oscilloscope, the probe selection of oscilloscope is very important!Below we will discuss some commonly used oscilloscope probe types and scope of use, to give you some guidelines, less detour.
General probes into active voltage probe, passive probe, differential probe, current probe, low capacitance probe, high voltage probe and so on.
Active voltage probe: generally suitable for single-terminal signal whose bandwidth is more than 500M Hz and amplitude is less than plus or minus 3 volts. Teck's active voltage probes are P7260, P7240, TAP1500, etc.Some models can measure 3dB bandwidth up to 6G.
Passive probe: generally used for testing single-end signals with bandwidth less than 500M Hz.It is an economical probe.The typical input capacitance is 8pF. The highest voltage is 300 Vrms. The compensation range is 8 to 12 pF.
Differential probe: generally used to test differential signals.It is divided into high bandwidth and high voltage.The high-voltage differential probe can test differential signals up to 4400 volts.The high bandwidth differential probe can test high speed signals up to 12.5G.Some products can even reach 16G Hz.
Current probe: hall effect is usually used to test current signal.The test range is generally from DC to 2G.The range is from 1 mA to 20000A.
Low capacitance probe: this is the probe set for matching.At present, there are few market models of this probe, which can measure bandwidth up to 9G Hz.
High voltage probe: suitable for testing high voltage signal, can measure up to 4000 volts, can be divided into single end and differential probe.
