In 2000, IET Labs acquired the GenRad standards, impedance decades, megohmmeters, digibridges, audio and strobe lines and now continues to manufacture, service and support these “In the Genrad Tradition…”

IET Labs – GenRad Impedance Instruments

Products include the Standards and Decades products (Resistance, Capacitance, Inductance), Digibridges, Megohmmeters, Audio products, and Strobotac lines.

GenRad 1546 Digital Stroboscope

Since GenRad introduced the first commercial electronic stroboscope in the 1930’s, the GR models have remained the world standard.

GenRad 1546 Digital Stroboscope

The GenRad 1546 digital stroboscope emits a high-intensity, short-duration flash of light. The stroboscope features an electronic pulse generator that controls the flash rate, a line-operated power supply, and a light-emitting diode (LED) five digit readout in flashes per minute.

The instrument has internally and externally triggered modes of operation. In the Internal mode, the stroboscopes flash is triggered by an internal oscillator pulse which can also drive other IET stroboscopes for additional light sources. In the External mode, the 1546 operates as a digital tachometer.

TTi – Thurlby Thandar Instruments

The LD400 is an inexpensive 400 watt electronic load which is suitable for testing and characterising a wide variety of dc power sources.

 LD400 – DC Electronic Load – TTi

Its wide voltage/current range, multiple operating modes and built-in transient generator give it the versatility to offer test solutions from the design laboratory through to the component test area.

LD400 - DC Electronic Load - TTi

The LD400 can operate at voltages below 500mV for currents up to 10 amps. At higher currents the fixed minimum resistance (typically better than 25milliOhms) gradually raises the minimum operating voltage, but it remains below 1 volt up to 40 amps and below 2 volts up to 80 amps.
