CartPico attenuators allow you to increase the input range of your oscilloscope, or reduce the output level of fixed-amplitude signal sources. Pico terminators are useful for connecting signals from low-impedance sources into instruments with high-impedance inputs, such as oscilloscopes.
TA050 – Attenuator Set
The TA050 attenuator set consists of four coaxial attenuators designed for use with signals up to 1 GHz. Each attenuator has a male and a female BNC connector.
Usage note
The TA050 attenuators must be used with a matched 50-ohm source and load. If you wish to attenuate a signal before feeding it into a high-impedance measuring instrument, you must add a 50-ohm feedthrough terminator such as the Pico Technology TA051 feedthrough terminator.
