UNI-T UTG4082A Generator

The UTG4082A Function/Arbitrary Waveform Generator is a modern dual-channel generator utilising direct digital synthesis technology to produce an accurate and stable output of arbitrary waveforms with a resolution of 1 µHz, a maximum output frequency of 80 MHz and a sampling rate of 500 MS/s. The output signals include sine, square, sawtooth, harmonic, pulse, Gaussian noise, DC and arbitrary waveforms.
Multiple modulation modes are available, including AM, FM, ASK, FSK and PSK, as well as signal modulation using PWM, BPSK, QPSK, OSK, DSB-AM, SUM, QAM, frequency sweep, etc., from an internal or external source, with linear and logarithmic sweeping.
The generator is intended for use in the design, development, testing, troubleshooting and repair of electronic and electroacoustic equipment, such as the testing of circuits and devices in cellular and wireless systems, radio and television systems; testing of semiconductor components, etc. Thanks to DDS technology, it is capable of generating precise and clean signals with minimal distortion.
A user-friendly panel with simple controls and a clear display allows you to work much more efficiently and quickly. It features a USB interface and powerful software for transferring data to a computer.
The internal 7GB non-volatile memory stores more than 160 waveform traces, e.g. mathematical, bioelectrical, medical, trigonometric, antitrigonometric, transient phenomena in motor vehicles, etc. You can store a waveform of any type up to 32 Mpts in length in this memory. It also features a built-in frequency meter (counter) for external TTL signals up to 800 MHz. It offers an excellent price-to-performance ratio and a wide range of functions. It is suitable for use in university laboratories, research institutes, etc. This instrument complies with the safety requirements of IEC 61010-1, up to the CAT II 300 V insulation and overvoltage standard.
