WebJun 29, 2024 · No active components—such as transistors or amplifiers—are used within these types of probes. Generally speaking, passive probes are easy to use, relatively inexpensive, and fairly rugged. Passive probes are typically available in the following configurations: 1×: no attenuation; 10×: factor-of-10 attenuation; 100×: factor-of-100 … WebThese are passive attenuators. They are very simple objects based on a resistive partition housed in male-female RCA connectors and can be used in particular when there are differences in sensivity between the source (CD player, preamp, etc.) and the amplifier.

WebOct 13, 2024 · The following simple circuit provides "6" dB attenuation and 50 Ω input impedance, assuming that the load at the output is also 50 Ω. (To be precise, it is an attenuator with a attenuation factor of 0.5 or 6.021 dB) simulate this circuit – Schematic created using CircuitLab Web1. The common-mode voltage in this circuit does not vary with input voltage. 2. The input impedance is determined by the input resistor. Make sure this value is large when compared to the output impedance of the source. 3. Using high-value resistors can degrade the phase margin of the circuit and introduce additional noise in the circuit. WebMay 5, 2024 · There are three principal passive attenuator configurations named after letters that their schematics resemble: L, T, and π. Each of these configurations can be either balanced or unbalanced. The balanced counterpart of the T-pad attenuator is known as an H-pad. Another variation is the bridge T-pad. The balanced π-pad is an O-pad. oxy dry sheeter
