This handy tool lets you test active and passive components at frequencies up to 3 GHz. I tried an early unit, using it for radiated and conducted EMI emissions testing. After almost ten years, Picotest has launched a new version of its Harmonic Comb Injector (generator). The J2150B ($495) is one of the pieces I’ve […]

APEC 2025 test equipment: power sources and loads
Powering electronic devices requires the testing of power supply and charging circuits, battery management systems (BMSs), and battery cells. Many of these circuits require voltage, current, and power measurements, plus numerous others. Oscilloscopes and probes let you see the waveforms in power-delivery circuits, but the circuits themselves may need simulated batteries and simulated loads. That’s […]
Review: PCBite circuit board holder and probe kit
The PCBite kit holds your circuit board in place while you probe it, reducing the risk of short circuits. Recently, I’ve had to test and characterize many small PC boards, including embedded processors, DC-DC converters, and other wireless-related products, for EMC issues. I’ve never really had an easy way to keep these boards from moving […]
Water-cooled probe injects disturbances onto power rails
The P2124 from Picotest let’s you inject modulation signals onto your board’s power rails for noise immunity testing.
