Tektronix , Inc.a provider of test, measurement and monitoring instrumentation has introduced new AWG5000 series of arbitrary waveform generators (AWG), built on the same platform as the recently introduced AWG7000 series.
With a single AWG5000, customers are able to generate high-resolution signals for testing both analogue and digital baseband and intermediate frequency (IF) circuits in mixed-signal devices, increasing test efficiency and reducing costs. The AWG5000 is ideal for testing digital RF technologies including software defined radios and radars, WiMAX, WiFi, MIMO and UWB.
Digital RF refers to the integration of digital computing and traditional analogue radio frequency technologies and is a major technical driver enabling new wireless applications. Digital RF applications combine both digital and analogue signal processing technology such as analogue-to-digital converters (ADCs), digital-to-analogue converters (DACs), and RF functions that is within a single device, presenting unique test requirements.
With variable sample rates up to 1.2 GS/s and 14- bit resolution, either two or four analogue channels and up to 28 digital outputs, the AWG5000 series enables engineers to effectively and efficiently test emerging digital RF applications using real-world signals.
According to Tektronix, the integration of digital and analogue circuits in digital RF designs can lead to implementation challenges. Engineers performing design validation and characterisation of mixed-signal devices often have to depend on multiple instruments with complex and expensive test setups for their signal generation needs. The Tektronix AWG5000 solves this problem.
The AWG5000 provides both analogue and digital IQ signals and direct IF beyond the capabilities of any single alternative such as RF signal or pulse pattern generators. With a single instrument, the AWG5000 provides engineers with an efficient test signal generator for both digital baseband and IF.
AWG5000 provides complete digital and analogue signal generation capabilities
Depending on whether the interface between baseband and RF is analogue or digital, engineers require a signal generator with both high vertical resolution and spurious free dynamic range (SFDR) for analogue I/Q (in-phase carrier amplitude/quadrature phase carrier amplitude) and IF, or with parallel digital outputs for digital I/Q.
A signal generator with both analogue and parallel digital outputs for digital baseband is ideal for creating, replicating and generating either ideal, distorted or real-life signals including noise, jitter, glitches and other imperfections to assist with prototype debug and verification of the baseband/RF interface.
The AWG5000 series consists of four models, offering two and four analogue channels with two versions of each, with variable sample rates up to 600 MS/s and 1.2 GS/s. All four models of the AWG5000 feature 14-bit vertical resolution enabling signal generation with a high 80dB SFDR and two digital markers per analogue channel.
The two channel versions feature an option for a pair of 14-bit parallel digital outputs which enable test of digital IF or digital I/Q systems. Additionally, the four channel models are ideal for test of 4x4 MIMO systems. The combination of speed, resolution and digital output capability is good, making the AWG5000 one of the first signal generators capable of meeting mixed signal test needs.
Greater ease-of-use and productivity
Tektronix user experience designers researched signal source customer usage patterns and needs to determine requirements for the AWG5000. Based upon this research, the AWG5000 is equipped with a 10.4 inch LCD touch screen colour display and an intuitive user interface employing Windows XP to help engineers be more productive.
The integrated display and UI reduces the need for external devices and enables faster and easier setup, thus reducing time to productivity. The AWG5000 offers better usability for the lab. Additionally, with Gigabit Ethernet LAN and GPIB interfaces, the AWG5000 provides the necessary interface control for use in manufacturing.
The AWG5000 enables easy data interchange with third-party software including MatLab, MathCad and Microsoft Excel, which are often used in the creation and generation of waveforms, data streams and mixed signals as an aid to design, prototype, debug and test compliance of the new products.
In addition to being ideally suited for the digital RF world, the AWG5000 with its range of mixed signal analog and digital signal generation capabilities follow its predecessor products, the AWG400 and AWG500 series as being the mixed signal generation tool of choice for designers of signal conversion devices such as D/A and A/D converters, display and imaging devices and consumer and and computing devices.
