The FG502 function generator plug-in pulls out for easy service (Fig. 4). The side panels pop open so you can get to both sides of the printed circuit ... failure-prone. Analog guru Jim Williams ...

Anyone searching for a function generator ... No need for passive analog components, which simplifies the design and enhances reliability. – Modular design: Every sub-circuit is a pre-defined ...

This all-analog circuit provides three ... The simplified block circuit shows IC1 operating as a square-wave generator with frequency determined mainly by R1 and C1 (Fig. 1).
