When using the network analyzer to measure impedance, such as the capacitance and ESR or a capacitor, or the DCR of an inductor, etc., it is often necessary to provide a voltage bias to the device being tested. This is true of semiconductor junction capacitances, varactors, and some ceramic capacitors (especially X5R). In these cases the impedance is a function of the DC bias on the device. The Picotest DC bias injector (J2130A) is used for this purpose during impedance measurements.

Quantum SMART Fixture - Accel-RF Corporation

Accel-RF Corporation, the world leader in turnkey RF automated reliability test instruments, has "unplugged" the industry-leading RF SMART Fixture from their automated test platform and made it available for benchtop test. The NEW Quantum SMART Fixture is a programmable self-contained DC bias and RF stimulus control module capable of synchronizing sequenced independent pulsed-bias and pulsed-RF signals to a DUT or remote fixture. The signals are controlled from a user interface compatible with Accel-RF's LIFETEST software. The Quantum SMART fixture is capable of "active" temperature control and monitoring of a remote DUT through embedded firmware in the microprocessor
