    1 in stock

    ScanaQuad series of logic analyzers and signals generators are four channel, USB powered devices that allow you to capture signals, visualize and analyze them on a host computer software, and generate signals. Generated signals may be arbitrarily created signals, or the user may play back previously captured signals. ScanaQuad offers an intuitive way of analyzing logic signals, backed with exciting features like enhanced ±35V input protection, adjustable input threshold, direct connection to RS232/485, CAN and LIN buses, ability to trigger on specific protocols (like a UART word or an I²C address). The signal generator end was designed to be very versatile: Precise control over loop point can be achieved as well as the ability to generate arbitrary signals on any number of channels while recording the result on the others. ScanaQuad input/output stage is fully protected while offering flexible options like Open Drain outputs and configurable pull up/down resistors. Furthermore, the digital signal generator has an adjustable output voltage from 1.6V to 5V, which covers most TTL, CMOS, and LVCMOS applications. Features 4 channels configurable as input or outputs 200MHz Sampling frequency 4M Points memory per channel Adjustable input threshold from 0.5V -> 3V Input protection up to ±35V 2 configurable differential input pairs Adjustable digital output voltage level 1.8V -> 5V Optional pull up/down resistors on all probes Outputs can be configured as open-drain Included ScanaQuad SQ200 device USB cable 5 pins gripper probes cables

What is a signal generator or function generator? Why are signal generators necessary?

A signal generator or function generator is an analog or digital device that generates voltage waveforms at a predetermined frequency and applies them to a device under test. A signal generator is an essential tool for testing circuits. A signal generator is easy to operate thanks to the buttons and switches on the main panel, which allow you to adjust the most important aspects of a waveform, such as its speed, amplitude, and offset, as well as add simple distortion and modulation.

What are the most common signal generators?

When it comes to possible applications, we'll go through some of the most common signal generators, each serving a different function. To generate simple repetitive waveforms – and to improve, test and repair electronic equipment – you can use a function generator.

The sine wave is the most common waveform, but sawtooth, step (pulse), square, and triangle waveform oscillators are also common. You can also use them to test amplifiers or to introduce an error signal into a control loop. The ability to add a DC offset is another feature found on many function generators. Function generators are usually used with analog circuits.

Although function generators cover both audio and RF frequencies, they are rarely used in applications that require low distortion or stable frequency signals. Other signal generators are better suited when those features are needed.

A complex signal generator, an arbitrary waveform generator (AWG or ARB), creates arbitrary waveforms within a certain frequency range, accuracy, and output level. Unlike a function generator, which can only output a limited number of waveforms, an AWG allows you to select a waveform as a source in several ways. If you want an application with a higher design and testing level, you use an AWG.

RF signal generators are used in wireless communications applications. They usually support analog modulation such as AM, FM, and PM. RF signal generators are therefore intended for anyone involved in RF or microwave testing and development.

Audio signal generators are signal generators used for the sound range, from 20 Hz to 20 kHz and above. They produce sine waves for audio applications. In addition, their most striking features are the audio measurements of frequency response and distortion measurements. Audio signal generators should have a flat response and low levels of harmonic distortion.
