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 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 femto-second-range can be achieved and maintained.
