Thursday, November 14, 2013: Signal generators or function generators are electronic devices that generate repeating or non-repeating electronic signals (in either the analogue or digital domains). They are generally used to design, test, troubleshoot and repair electronic or electroacoustic devices. Major factors that are presently driving the signal generators industry are the rapid developments in the communications industry, huge potential in the Asia Pacific market, and continuous growth of the demand for signal generators in the aerospace and defence sectors. In this section, we feature signal generators and analysers that were launched in India in the past seven months. However, companies like Teledyne LeCroy, Yokogawa, Aeroflex have not launched any products in this space in this period.
Model: 4050 series, Brand: B&K Precision, Manufacturer: B&K Precision Corporation, USA
Launched in August 2013, the 4050 series is a line of four dual-channel function/arbitrary waveform generators.
Key features
-
All models are dual-channel, providing a main output voltage that can be varied from 0 to 10 Vpp into 50 ohms, and a secondary output that can be varied from 0 to 3 Vpp into 50 ohms
-
Their large 8.89cm colour LCD display, rotary control knob, and numeric keypad with dedicated waveform keys and output buttons make waveform adjustments quick and effortless
-
The 4050 series provides users 48 built-in arbitrary waveforms and the ability to create and load up to 10 custom 16 kpt waveforms using the included waveform editing software
