The Instek MFG-2120MA is a single-channel 20 MHz ARB function generator with a pulse generator, whose frequency reaches 25 MHz. The AFG channel of the MFG2120MA outputs sine, square, and triangle, etc. The MFG-2120MA features true point-by-point output arbitrary waveform characteristics of 200 MSa/s sample rate, 100 MHz waveform repetition rate, 14 bit resolution, and 16k point memory depth. Independent input/output power amplifier with 20W, 10dB, DC-100KHz bandwidth, and distortion less than 0.1% can be applied to the audio application.

The overall design of the MFG-2120MA is earth ground isolation among output/input terminals and instrument chassis that can only be found in high-level signal sources. The output channels can sustain maximum isolation voltage up to ±42Vpk (DC+ AC peak value) to earth ground that is ideal for floating circuit tests. Multi-unit outputs can be executed without factoring in grounding reference issue. There is no additional isolation requirement for experiments such as "full-wave rectification" and "voltage doubler" which are easy and safe. An external power supply can bring up the DC bias voltage to ±42Vpk to meet the requirements of higher DC bias voltage such as automotive and educational applications.
