　　The current injector is one of the most versatile of the injector products. Coupled with the G5100A, or other equivalent function generator, it is capable of performing small signal load steps up to 40MHz, with very fast rising and falling edges. Using the G5100A, also allows the rise and fall times to be controlled, various waveforms or even arbitrary waveforms. This can be used to simulate the effects of many different types of loads, including high speed digital circuit loading, which is often largely dynamic.

　　The current injector can also be used to measure output impedance of power supplies, voltage regulators, power buses and even batteries. It can be used to non-invasively measure the stability of a combined input filter and the negative resistance of a switching power supply. It also has application in the measurement and extraction of transistor data, including small signal 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.

　　Measuring Output Impedance

　　The current injector has two connections for the output, Output and GND. The input is DC+AC and can be connected to either a signal generator or a network analyzer. A built in bias current enables Class A operation for use with a network analyzer. The Current Injector and DC Bias injector can also be used for this purpose.

　　The output current is reduced 40dB from the input signal, resulting in 10mA/V scaling. The current monitor is designed to be terminated into 50 Ohms and can be used with the network analyzer, an oscilloscope or a DMM to monitor current.

　　When used in conjunction with a voltage probe, the analyzer can measure Voltage/Current, which is the impedance. SpecificationsCharacteristicTypicalMaximum Input Voltage DC+ACVcc-1.5VOutput VoltageVcc-2VCurrent Monitor1V / AModulator Gain10mA / VOffset Current (typical)+/-24mAUsable BandwidthDC ~ 40MHzTemperature Range0 ~ 50°CMaximum Altitude6000 Ft

　　   J2112A - Product Information

　　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.
