Palo Alto, Calif. At the European Microwave Week 2005 conference and show, Agilent Technologies rolled out two additional models to its N6030A Series AWG (arbitrary waveform generator) family. The company now has four different AWGs with various bandwidths and fidelity ranges to meet the varying needs of our aerospace and defense and emerging-communications engineers.
The N6032A, a dual-channel AWG designed for radar and military communications, delivers 625-Msample/s performance, with 15 bits of vertical resolution per channel. It can create wideband waveforms up to 250-MHz wide.
The N6033A, designed for satellite communications and general-purpose wideband applications, delivers the same speed but with 10 bits of vertical resolution per channel. That makes it a low-cost dual-channel AWG.
Three new software options build upon the N6030A Series's ability to create realistic wideband signal simulations. A DDS (direct digital synthesis) software option (dubbed Option 330) lets radar and emerging-communications engineers create basic waveforms in the AWG's memory and then modify the behavior with profiles for AM (amplitude modulation), PM (phase modulation), and FM (frequency modulation).
This capability lets you simulate testing without the time and expense of field trials, such as in-flight and in-orbit testing. This option can also be used to simulate fading profiles in receiver testing for satellite and 4G (fourth generation) signals, such as MIMO (multiple input, multiple output) formats.
A second software option is dynamic sequencing. Sequencing software (Option 300) enables radar and military communications engineers to build custom signal scenarios on-the-fly. You can dynamically access up to 16k of previously stored sequences through a 16-bit interface, and then re-play these complex waveforms to respond to changing threat environments, or to create signals where the next waveform to be played isn't known in advance.
The last of the three software options is an AWGN (additive white Gaussian noise) option. Dubbed Option 250, it lets receiver designers perform front-end receiver testing without expensive external noise signal sources. Controlled amounts of wideband noise pedestals (500-MHz wide) can be added to test waveforms.
This can help you better understand receiver sensitivity such as Eb/Nothe ratio of a signal's energy per bit (Eb) to the spectrum noise density (No)versus BER (bit-error rate). Because both the reference waveform and noise pedestal are generated inside the AWG, you can avoid measurement drift and errors normally associated with manually combining the two signals externally.
