Signal Generator by Keysight Technologies

Note : Your request will be directed to Keysight Technologies.

The M8199A from Keysight is an Arbitrary Waveform Generator (AWG) with an analog bandwidth of up to 70 GHz. It provides research engineers a high-performance signal source for arbitrary signals, enabling development of designs up to 140 GBaud. The generator has high flexibility with upgrade options from 2 channels at 128 GSa/s to 4 channels at 256 GSa/s. The M8199A 256 GSa/s AWG delivers twice the sampling rate of any AWG on the market (as for April 2021), coupled with at least 50 percent higher analog bandwidth. This allows research engineers to quickly develop advanced components for terabit transmission systems.

The M8199A allows dual polarization testing in a small form factor and the generation of complex signals with any modulation scheme (QPSK, nQAM, etc.). It has built-in frequency and phase response calibration for clean output signals with intrinsic jitter of less than 75 fs. The AWG incorporates digital correction techniques for frequency- and phase-response compensation of the AWG output and any external circuit to generate the desired signal at the device under test.

The M8199A is controlled by the M8070B systems application software. It includes a free MATLAB based utility called IQtools along with the instrument software. IQtools provides many waveform generation utilities as well as an option to download user-defined waveforms. IQtools also supports “in-system calibration” to measure and compensate the frequency and phase response of the AWG and any external circuitry. It can compensate skew between all channels.

The M8199A is an ideal solution to test various optical systems from discrete components like optical power amplifiers to more complex dual polarization systems such as optical modulators or optical receivers. Even for tests of signal processor ASICs or algorithm, this AWG is an excellent signal source to provide stressed signals to these devices. With high sampling rates, this generator has enough oversampling gain to generate extremely broad bandwidth, yet high fidelity RF signals for wireless and aerospace/defence applications. It can generate any arbitrary waveform that can be mathematically described (for example, a signal calculated in MATLAB can be downloaded directly into the M8199A).
