Tektronix CFG280 Function Generator

The CFG280 is a Function Generator from Tektronix. A function generator is a type of signal generator people use to generate many kinds of electrical waveforms over a range of frequencies.

• Frequency range: 0.1 Hz to 11 MHz (Calibrated); 0.01 Hz to 11 MHz (Uncalibrated)
• 1 Hz to 100 MHz Counter
• Square, Triangle and Sine Waves; TTL Output
• 20 dB Attenuator
• External Gate Input
• VCF (FM) Input
• AM 0 to 100% Input for External Sine Wave
• Internal or External Frequency Sweep
