Line Injector
J2120A
-
While the injection transformer is a very wideband adapter, it is not useful for measuring ripple rejection (PSRR) of a power supply or even an opamp. This is because the attributes that make the injection transformer perform so well also result in a transformer that is intolerant of DC current. Even very small DC currents (5mA or less) can greatly reduce the signal capacity or even totally saturate the transformer. For this reason, the Picotest line injector (J2120A) is another essential test adapter.

Power Line Isolators & Conditioners
-
A power line conditioner (also known as a line conditioner or power line conditioner) is a device intended to improve the quality of the power that is delivered to electrical load equipment. While there is no official definition of a power conditioner, the term most often refers to a device that acts in one or more ways to deliver a voltage of the proper level and characteristics to enable load equipment to function properly.In a nutshell, poor incoming electrical power converted to good output power.

Transmission Line Probes
-
Transmission line probes are a special type of passive probe designed for use at very high frequencies. They replace the high impedance probe cable found in a traditional passive probe with a precision transmission line, with a characteristic impedance that matches the oscilloscope input (50 Ohm). This greatly reduces the input capacitance to a fraction of a picofarad, minimizing the loading of high frequency signals. A matching network at the tip increases the DC input resistance. While they have lower DC input resistance than a traditional passive probe (usually 500 Ohm) to 1kOhm), the input impedance of these probes remains nearly constant over their entire frequency range. A traditional /10 passive probe will have a 10 MOhm) input impedance at DC, however this impedance drops rapidly with frequency, passing below the input impedance of a transmission line probe at less than 100 MHz.

Power Line EMI Adapters
-
How much EMI noise is on your power lines indeed? How to assess the levels of noise and its properties when it is obviously a bad idea to connect your oscilloscope or a spectrum analyzer directly to your power lines?Our EMI interface adapters provide a barrier for high mains voltages but a straight passage for high-frequency signals so that you can connect your sensitive instrument to power lines for analysis and quantification. We offer plug-in and hand-held adapters which can measure both differential ("normal") and common-mode noise.
