 Key Applications

As devices and interfaces become faster and more complex, the M8195A AWG gives you the versatility to create the signals you need for digital applications, optical and electrical communication, advanced research, wideband radar and satcom.

Coherent optical – a single M8195A module can generate two independent I/Q baseband signals (dual polarization = 4 channels) at up to 32 GBaud (and beyond).

Multi-level / Multi-channel digital signals – generate PRBS2, NRZ, PAM4, PAM8, DMT, etc. signals of up to 32 Gbaud. Embed/de-embed channels, add jitter, ISI, noise and other distortions.

Physics, chemistry and electronics research – generate any mathematically defined arbitrary waveforms, ultra-short yet precise pulses and extremely wideband chirps.

Wideband RF/μW – generate extreme wideband RF signals with an instantaneous bandwidth of DC to 25 GHz for aerospace/defense/communication  applications

Coherent optical applications

The M8195A supports leading edge research for 100 Gb/s, 400 Gb/s and 1 Tb/s optical transmission systems that require a very wideband electrical stimulus with a variety of complex modulation formats from QPSK to nQAM to OFDM at symbol rates up to 32 GBaud and beyond.

In order to drive dual-polarization systems, the M8195A has 4 independent, yet precisely synchronized analog output channels in a single module. Since all 4 channels are generated by the same instrument without any external circuitry, precise synchronization down to the fem to-second-range can be achieved and maintained.

The M8195A uses digital pre-distortion techniques for frequency- and phase-response compensation of the AWG output and any external circuits. These are required in order to achieve a clean signal at the device under test.

Distortions generated by cables, amplifiers, etc. can also be compensated by embedding /de-embedding the S-parameters of the respective circuits or by performing an in-situ calibration using Keysight 81195A Optical Modulation Generator software.

In conjunction with the 81195A Optical Modulation Generator software clean signals and signals stressed with impairment patterns can be generated both offline on a PC or in real-time using the hardware DSP block, which allows the parameters of the waveform (e.g., the pulse shaping filter coefficients) and impairment generation to be adjusted at run-time without downloading a new waveform.

Multi-level/multi-channel digital signals

Increasing the data throughput on digital interfaces has traditionally been accomplished by increasing the data rate or by increasing the number of parallel signals. However, at a certain point, it is more cost-effective to consider multi-level signaling techniques. Examples are high-speed backplane connections using PAM4 or PAM8, and also technologies in the mobile application space.

The M8195A is ideally suited to address those multi-level/multi-channel interfaces using any standard or custom data format, such as PAM-n (n = 3,4,5,...) or DMT. The M8195A supports pattern lengths up to PRBS 231-1* and baud rates up to 32 GBaud, including the necessary parameter changes, such as variable transition times, various pulse-shaping filters, adding distortions, and can also generate PAM-n signals with non-equidistant voltage levels. The flexibility of the waveform generation at highest speeds, combined with excellent intrinsic jitter performance makes the M8195A truly a future-proof instrument – independent of the direction technology is moving.

At data rates of multiple Gb/s, the effect of cables, board traces, connectors etc. have to be taken into account in order to generate the desired signal at the test point of the device under test. The M8195A incorporates digital pre-distortion 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. Channels can be embedded/de-embedded if the S-parameters of the respective circuits are provided.

With up to 4 differential output channels per 1-slot AXIe module and the ability to synchronize multiple modules, the M8195A is well-suited to stimulate multi-lane high-speed interfaces in a very economic fashion.

With the integration of the M8195A AWG into the M8000 Series of BER test solutions, Keysight allows you to address your high-speed digital receiver test needs with the M8070A software platform and choose the BERT or AWG that best meets your needs.

Physics, chemistry and electronics research

You can generate any arbitrary waveform that you can mathematically describe (e.g. in MATLAB) and download it directly to the M8195A. This includes ultra-short yet precise pulses down to ~100 ps pulse width or extremely short, yet wideband RF pulses and chirps.

In conjunction with the M8197A synchronization module, these signals can be triggered from external sources with very low jitter.

Wideband RF/μW signals

The M8195A can address wideband wireless, EW and comms/satcom applications where extremely wide instantaneous bandwidth (DC to 25 GHz) and fast frequency hopping are critical parameters.

With built-in frequency and phase calibration, it is straight forward to generate wideband multi-tone signals with a flat frequency response up to 25 GHz.

Wideband wireless signals with any modulation scheme (e.g. nPSK, nQAM, APSK, OFDM, etc.) can be generated directly at carrier frequencies of up to 25 GHz. In many cases, this saves an additional up-conversion stage (e.g. in case of IEEE 802.11ad) or enables waveform generation directly at the carrier frequency.

Note that the available frequency range depends on the number of channels that are used simultaneously as well as the amount of memory per channel (see sample memory modes in this document).
