Introducing the JUNTEK Dual Channel Signal Generator also known as the PSG9080, a programmable function arbitrary wave source that boasts a maximum frequency of 80MHz.
With the ability to output various waveforms and voltage-controlled adjustments, this little device packs a punch.

The versatility of the JUNTEK PSG9080 is impressive with its ability to output sine waves, square waves, triangle waves, and arbitrary waves. The firmware can be updated in real-time ensuring any bugs are quickly fixed. The high sampling rate of up to 300MSa/s allows for more waveform data per unit time, resulting in more precise outputs. Modulation functions are also available in single or dual channels. However, it's worth noting that some shortcomings have been reported with signal modulation, specifically with FM modulation where the carrier is downshifted by several kHz when switched on with no audio signal.

While there are a few cons to consider such as the reported shortcomings in signal modulation, the JUNTEK PSG9080 is a powerful tool that cannot be missed on any electronic technician's desk. The ability to control the frequency, amplitude, and duty cycle of the output using an external analog voltage is a major pro. The firmware upgrade feature is also a plus for keeping the device up-to-date.

To put it simply the JUNTEK PSG9080 is an excellent product that delivers on its promises. It's perfect for hobbyists and professionals alike who need a reliable signal generator that won't break the bank. This product should definitely be considered if you're looking for a top performer in its category.
