J2112A - 產品说明

The J2112A Current Injector is an extremely versatile tool addition to the Picotest Signal Injector line-up. Coupled with the G5100A AWG, or other equivalent function generator, it is capable of performing small and large-signal load steps up to 40MHz, with up to 20ns rise/fall times, and with currents up to 1amp. Rise and fall times can be controlled and arbitrary waveforms can be used to drive the injector producing load current profiles of virtually any characteristic pattern. This is ideal for emulating all types of load conditions, including high speed digital circuit loading, battery discharge profiles, or spontaneous current spikes.

When coupled with a network analyzer, the Current Injector can be used to measure the output impedance of all types of circuits and systems including power supplies, voltage regulators, power buses, and batteries. It can be used to NON-INVASIVELY measure the stability of a combined input filter /negative resistance of a switching power supply or the phase margin of a linear or switching regulator WITHOUT the need to break the control loop.

It also supports applications in the measurement and extraction of transistor data, including current gain, Ft, and many other dynamic performance parameters. In RF and instrumentation circuits it can be used to provide constant current biasing for class A amplifiers and buffers.
