AFG31000 Series - 2

Datasheet Basic and Advanced Modes The AFG31000 series is the industry’s first arbitrary function generator with full function Basic (AFG) and Advanced (Sequence) modes. In Basic mode, the AFG31000 generates traditional functions and arbitrary waveforms. The touchscreen and front-panel controls make it simple to set up. Basic mode lets you change frequency without the need to worry about waveform length and sample rate. This feature is useful in analog designs that characterize filter/amplifier frequency responses or in digital designs where clock rates change frequently. Advanced mode lets...

AFG31000 Series - 3

AFG31000 Series InstaView™ technology shows the actual waveform at the DUT Most waveform generators assume they are driving a 50 Ω impedance. However, most devices under test do not have a 50 Ω impedance. This mismatch results in an inconsistency between the waveform as set on the AFG and the signal at the DUT. With InstaView turned on, the AFG31000 shows the waveform as observed at the DUT. A large touch screen and smart user interface With InstaView turned off, the AFG31000 works like a traditional function generator. Due to an impedance mismatch, the AFG display shows a different...

AFG31000 Series - 4

Datasheet Built-in ArbBuilder tool makes creating and editing arbitrary waveforms easier than ever In the past, you needed a PC with waveform editing software to create or edit your arbitrary waveforms. The waveform would then need to be downloaded to the AFG using either a USB stick or a data cable connection. The process was time-consuming, especially when waveforms required frequent changes. ArbBuilder is a built-in application on the AFG31000 series that lets you create and edit your arbitrary waveforms directly on the generator. You can create arbitrary waveforms with the Equation...

AFG31000 Series Double Pulse Test Reduce development time with ready-to-use, built-in applications The AFG31000 includes Double PulseTest, a downloadable plugin software application that enables double pulse applications for the power and semiconductor markets. The Double Pulse Test user interface provides touch-and-swipe or point-and-click control for generating at least two varying pulse widths. These pulses can be output to an isolated gate driver to trigger power devices such as MOSFETs or IGBTs. The Double Pulse Test on the AFG31000 offers the design and test engineer the ability to...
