Experienced AFG3000 users will find it especially easy to set up the new AFG2021. A The internal 4 128 kS memory and the USB memory expansion 3.5 inch color TFT screen shows relevant parameters in both graphic and capability provide substantial capacity for defining complex waveforms text formats, so you can have full confidence in your settings and focus on USB remote control port and USB flash drive port are included. GPIB the task at hand. The front-panel shortcut buttons and rotary knob provide and LAN interfaces are available as an option quick access to the most frequently used functions and settings. Built-in Modulation, Noise Generator, Burst, and Sweep modes for greater versatility Built-in waveforms provide quick access to commonly used signals Large 3.5 inch color screen displays both graphical and numeric waveform information simultaneously Menu and online help in 8 languages www.tek.com 1Datasheet Excellent frequency agility Traditional function generators created their output signals using analog oscillators and signal conditioning. The Tektronix AFG2021 relies on Direct Digital Synthesis (DDS) techniques. DDS technology synthesizes waveforms by using a single clock frequency to generate any frequency within the instruments range. DDS architecture provides exceptional frequency agility, making it possible to program fast frequency and phase changes, which is useful for testing radio and satellite system components, amplifiers, and filters. ArbExpress software helps you easily duplicate real-world signals. Insert productivity with SignalExpress Every AFG2021 ships with a free copy of the Tektronix Edition of National Instruments LabVIEW SignalExpress software for basic instrument control, data logging, and analysis. SignalExpress supports the range of Tektronix bench instruments enabling you to connect your entire test bench. You can then access each instrument from one intuitive software interface. This allows you to automate complex measurements requiring multiple Frequency range from 1 Hz to 20 MHz, supports a wide range of amplifier instruments, log data for an extended period of time, time-correlate data and filter testing applications. from multiple instruments, and easily capture and analyze your results, all from your PC. Only Tektronix offers a connected test bench of intelligent instruments to simplify and speed debug of your complex design. ArbExpress for real-world waveforms with minimal effort Connectivity With ArbExpress software, you can quickly create waveforms that can be copied to the AFG2021 to meet custom stimulus requirements. ArbExpress Using the front-panel USB host port, you can save your customized supports direct connection to Tektronix oscilloscopes and AFGs through waveforms or instrument settings onto a USB memory stick. Reloading the USB, GPIB, or LAN. The software allows you to import real-world signals data is easily done by plugging the device back into the USB host port. The captured with an oscilloscope onto a PC, then edit and download them onto USB device port and optional GPIB/LAN ports provide multiple alternatives an AFG to duplicate the captured waveform. This is extremely useful for for connecting the AFG2021 to your PC for waveform download and remote automotive, medical, and industrial applications where recreating sensor control. output is critical to analyzing the integrity of the design. Compact form factor The 2U height and half-rack width form factor allow the AFG2021 to be stacked on other bench instruments, such as digital multimeters, power supplies, and frequency counters, saving valuable bench space. With the optional RMU2U rackmount kit, GPIB interface, and full SCPI support, the AFG2021 is a perfect solution for automated test systems. 2 www.tek.com
