In 1895 William Roentgen observed X-rays although he could not explain their mechanism. The following year Henri Becquerel demonstrated that certain compounds of uranium emitted radiation that resembled X-rays. He showed this activity differed from the phenomenon of phosphorescence. The radiation seemed to be emitted continuously from the uranium. Did this violate the well-known principle […]
Meters & Testers
Non-contact voltage true-rms ac/dc clamp meters measure voltage, current simultaneously
The new Fluke 377 FC and 378 FC Non-Contact Voltage True-RMS ac/dc Clamp Meters are the only clamp meters that make accurate non-contact voltage measurements without test leads. The Fluke 377 FC and 378 FC True-rms clamp meters use Field-Sense technology to make testing faster and safer, all without touching a live conductor. You get […]

A portfolio of Smart Bench Essentials (SBE) lab bench products deliver the power of four unique instruments, including a triple-output power supply, an arbitrary function generator, a digital multimeter and an oscilloscope, through one powerful graphical interface offering integrated data management and analysis capabilities. Keysight’s SBE lab bench products are reliable and capable instruments developed […]
Clamp meter optimized for photovoltaic system tests
A solar clamp meter can measure up to 2,000 Vdc and 1,500 Vac (using PVHV leads) during installation, maintenance, monitoring and testing of photovoltaic systems and standard ac or dc electrical equipment. The DCM1500S can also measure ac and dc current up to 1,500 A and offers a true RMS reading on the ac range […]
Kit verifies isolation effectiveness of RF shielded enclosures
The JRE TVK Isolation Tester can help verify the proper shielding isolation of RF enclosure test set-ups. This test combination, consisting of the STA-1, a sensitive handheld spectrum analyzer, and the HPSS-1, a high power 2.45-GHz test signal source, can easily and quickly measure enclosure isolation down to less than -100 dB. The TVK Isolation […]
Source measurement units reliably gauge currents from nanoamps to amps in a single sweep
The R&S NGU series of high-precision SMUs feature innovative current feedback amplifier technology that provides both maximum sensitivity and accuracy to reliably measure currents from nanoamps to amps in a single sweep. To handle rapidly changing load conditions typical of battery-powered communications devices switching between sleep and transmit modes, the R&S NGU features an optimized control loop […]
Programmable dc electronic loads offer four-mode operation, transient testing
The Teledyne LeCroy T3EL15030xP Programmable DC Electronic Loads are versatile test devices which feature four operating modes to provide wide ranging test capabilities. In Constant Current mode, the electronic loads will sink a constant current, regardless of the voltage at the device terminals. Its Constant Voltage mode causes a constant voltage to appear at its […]
Portable tester checks, verifies EV charging systems
The HT Instruments MacroEVtest is a portable device for verifying the operation of electric vehicle supply equipment (EVSE) and for safety tests in private and industrial environments. The MacroEVtest, in combination with the EV-Test100 EV adapter, connects to a charging station to allow the verification of the EVSE’s complete functionality and electrical safety in compliance […]
