Why Choose the FeelTech FY3200S?
This function generator is an ideal entry-level instrument for anyone needing reliable signal generation without a high budget. Its dual-channel design allows for testing components like filters and amplifiers with two different signals simultaneously. The DDS technology ensures good frequency stability and accuracy , while the arbitrary waveform function opens the door to more advanced projects by letting you simulate custom signal patterns . The built-in 100MHz frequency counter adds extra utility, making it a 2-in-1 tool for your bench.
Important Usage Note
The FeelTech FY3200S features a plastic housing and a Class II power supply (2-prong AC cord) without an earth ground connection. Due to internal EMC filtering, a small AC voltage can sometimes be present on the BNC ground. To ensure safe operation with other grounded equipment (like an oscilloscope), it is recommended to connect all devices to a common ground or consider modifying the unit with a 3-prong grounded AC jack, connecting the ground to the DC ground .
