Low-cost arbitrary/function generator for entry-level test/education

April 01, 2015 // By Graham Prophet
Tektronix’ AFG1022 offers a high level of price/performance, and integrates with the TekSmartLab Wireless Lab Management configuration.

Compared to scope-based signal generators or stand alone AFGs in its price class, the AFG1022 offers better performance and greater flexibility, Tek asserts. Key performance specifications include dual-channel, 25 MHz bandwidth with 1 mVpp to 10 Vpp output, 14-bit vertical resolution and 1 µHz frequency resolution. It provides a 125 Msample/sec sample rate along with 64 MB of built-in non-volatile memory and USB memory expansion for user-defined waveforms.

The instrument offers 50 built-in standard function and arbitrary waveforms with continuous, modulation, sweep and burst modes to cover almost all the test requirements found in basic education labs. A built-in 200 MHz counter with 6-digit resolution offers frequency, period, pulse width, and duty cycle measurements.

Colleges and universities globally are, Tek says, looking to outfit labs with modern test instrumentation to better prepare students for the real world. With the addition of the AFG1022, Tektronix offers educational institutions a complete set of affordable instruments including oscilloscopes, signal generators, digital multi-meters and power supplies, all tied together with TekSmartLab.

To maximise learning, the AFG1022 incorporates an intuitive user interface with a 3.95-in. TFT colour display, shortcut buttons and rotary knob for quick setting adjustments. It is priced at €532/ £438.
