M-Power-line
The M-Power-Line convinces with its robust design, high efficiency, compact dimensions and excellent price-performance ratio. By using a Power Factor Controller (PFC) the input voltage may vary from 100V to 254V. This means that the devices can be used anywhere in the world regardless of the typical national power supply system. The simple operation and easy readability of relevant characteristic values (target/actual/state/alarm message) make the devices particularly attractive for use in many branches of industry as well as research institutes.

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.

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.
