The TinyRFSG-Plus, which is completely independently developed by our store, is the world's first. Before designing this product, the owner had already purchased various portable signal sources and small desktop signal sources on Taobao. However, they found that these signal sources had inaccurate first power (i.e. without real calibration), second input power amplitude that did not meet the standards stated in the instructions, poor third frequency step accuracy, often ranging from 1KHz to 10KHz, and too many harmonics. The second and third harmonics were basically not suppressed by filters, so square waves were used for counting.

As an engineer, I also need an excellent portable, pocket signal source. My requirement for my own signal source is accurate power: it can easily calibrate other spectrometers; Good harmonic suppression: pure signal; Strong output capability: Try to achieve a maximum output of 15dBm. Of course, as the frequency increases, the output power will decrease, but I will also tell the customer where my limit is; Portable: compact, strong anti-interference ability, suitable for pocket use.

At the same time, as it is our own research and development, we accept customized hardware and upper computer requirements from customers. Specific issues can be discussed in detail. At present, it only supports power supply on the computer side, and the computer software is controlled through the VISA interface.
