Product Overview

ROHDE & SCHWARZ AFQ100A

The R&S AFQ100A from Rohde & Schwarz is a high performance self-contained and flexible baseband source that perfectly meets the requirements of digital baseband development and compolex modulation scheme generation and testing. Featuring a maximum clock rate of 300 MHz, a bandwidth of 200 MHz (RF) and a waveform memory of up to 1 Gsample, the R&S AFQ100A provides the functionality and flexibility that is required for development and production tests on receivers and components of modern digital communications standards such as WiMAX and LTE.

The R&S AFQ100A combines flexibility with outstanding signal quality. Their spurious suppression, for example, is first-rate and frequency response is extremely linear. All these essential features combined with a wealth of other functions make the R&S AFQ100A a very versatile baseband generator.

Digital communications are what the R&S AFQ100A was designed for:

• Variable memory clock rate (1 kHz to 300 MHz) can optimally be adjusted to the useful signal 
• RF bandwidth of 200 MHz, e.g. for compensating higher-order non-linearities of multicarrier power amplifiers (MCPA)
• Long signal duration of up to 1 Gsample (B11 option). Long signals are needed e.g. for bit error ratio (BER) measurements
• WinIQSIM2™ options for communications standards such as WiMAX, LTE, HSPA, etc.

Aerospace and defense applications

• High bandwidth for generating very short pulses with short rise and fall times
• Pulse Sequencer Software for generating complex pulse patterns (K6 option)
• Accuracy
• Removable hard disk to meet high security requirements

Outstanding signal quality

• Excellent spurious-free dynamic range (SFDR) of up to typ. 83 dBc
• Frequency response of typ. 0.1 dB across 100 MHz I/Q bandwidth
• Frequency response compensation
• Very pure sine-wave source

Broad scope of applications

• Analog I/Q outputs (balanced and unbalanced) and optional digital outputs, e.g. for D/A and A/D converter tests
• Multisegment waveform for reducing switching time between different test signals and thus improving test throughput
• Numerous trigger and marker capabilities, e.g. for synchronization with a DUT
• Optional BER measurements for characterizing receivers

Easy creation of test signals

• Digital standards using R&S®WinIQSIM2™
• Pulsed signals with Pulse Sequencer Software
• MATLAB Transfer Toolbox for easy interoperability with MATLAB®
• ARB Toolbox for converting numeric I/Q data into AFQ waveform files

Easy operation

• Remote control via GPIB, USB and LAN
• User interface via external monitor or Windows XP Remote Desktop
• USB connectors for USB equipment (keyboard, mouse, memory stick)
