Agilent 81180A AWG

Today's complex, high-speed waveforms are often unable to be generated by a standard signal generator, so an arbitrary waveform generator (AWG) is used. However, the frequency range and reach of an AWG often falls short compared to a signal generator.

The Agilent Technologies 81180A AWG pushes the waveform envelope further into generator territory, with a sample clock ranging from 10MSps to 4.2GSp sand with up to 12bit vertical resolution. The bench-top unit provides one or two channels (coupled or uncoupled) with channel-to-channel skew less than 3ns, and even allows two AWGs to be linked to provide up to four synchronized channels. Users can select 16 or 64 million points/channel.

The AWG's output stage offers three software selectable amplifiers: for I/Q applications with 1GHz, differential DC-coupled output; for maximum bandwidth and flatness for direct RF applications, with AC bandwidth greater than 1.5GHz; and for time-domain situation with lowest overshoot and jitter, with transition times of 600ps. In addition, there is dynamic user control, via an external input, of segments and sequences, and remote control via LAN, USB and even GPIB.

The Aglient 81180A AWG also supports integration with Matlab, LabView and Agilent's Signal Studio applications. The unit begins shipping in May; pricing begins at $46,500.
