Solid State Voltage Injector
J2110A
While it is possible to obtain high quality injection transformers with bandwidths as wide as 1Hz to 5MHz or more, in some cases this is still insufficient for some tests. For example a typical heater control loop might have a bandwidth of less than 1Hz while some linear regulators and opamp circuits can have bandwidths of up to 100MHz or in some cases even higher. For these applications, a solid state injector can provide the necessary bandwidth. A solid state injector can perform at DC, while the upper frequency limit is dictated by the components selected and the printed circuit board material and layout. It is possible to obtain a solid state injector with a working range of DC – 200MHz, though above 50MHz the interconnection between the injector and the circuit being tested can become quite critical. It is essential that ripple from the injector power supply does not dramatically degrade the dynamic range or the signal to noise ratio of the measurement. The resulting plots are often much cleaner when using a solid state injector than with a transformer injector.

High Current Transformers
High Current Transformer is designed to elevate and check the temperature of the conductors at high current levels, in order to simulate the current loading conditions found in electrical circuits. High Current Transformer is designed as an open type transformer that uses the test object as its secondary coil or has 1 or 2-turn self secondary winding. The conductors cores' temperature depends on the short-circuit high current caused by the test object. According to the current going through the test object, the test temperature of the conductor will change. The loop temperature is measured by a thermocouple probe which is directly connected to conductor.
