There is considerable interest in generating complex waveforms to test radar and communications systems. An arbitrary waveform generator (AWG) is one of the most flexible methods of signal simulation
The DITO Electrostatic Discharge test system from EM Test is designed to generate random electrostatic discharges, similar to those that occur between a human body and any other surface capable of a different voltage potential.
Trio Test & Measurement has released the Wonder Wave series of arbitrary waveform generators from Tabor. These combine the capabilities of digital conversion and control with the signal integrity of synthesised analog generators.
Scientech Technologies has introduced two oscilloscopes - Caddo 802 and Caddo 803. These microcontroller-based models provide freedom from mechanical switching and give the feel of smooth digital touch. Caddo 802 is a 20 MHz dual trace model while Caddo 803 gives 25 MHz two channel four trace.
Anritsu has introduced the Broadband Site Master S810D/S820D series cable and antenna analysers that are claimed to provide the widest frequency bandwidth of any handheld instrument, allowing for the precise detection of faults in cables and antennas used in wireless backhaul and defence/aerospace applications.
The Schaffner model MFO 6501 magnetic field testing device provides power frequency testing in accordance with EN/IEC 61000-4-8 and 61000-4-9. The device consists of a programmable low impedance power amplifier, driving magnetic loop antennas such as the INA 702 or 701, or loops to individual user requirements.
The DLRO200 digital low-resistance ohmmeter is suitable for the wide range of low-resistance testing applications which require test currents of up to 200 A. This instrument, which is one of the lightest in its class, is not only very portable, but also features a robust IP54 (splashproof) case which ensures that it will easily withstand the rigours of use on site.
Frequency selective devices such as amplifiers, filters, directional couplers, attenuators and the like are characterised by their performance versus frequency. Measuring these characteristics is performed by various methods, most are frequency swept
