Sine and square wave generator (IPC-4744-W). Frequency range 5Hz to 50kHz in four switched ranges plus a fine control. Accuracy typically ±10%. The output amplitude is continuously variable from zero to maximum 8V peak to peak with maximum output power 1W into 8 ohms. The output is taken from two 4mm sockets mounted on the front panel. An illuminated on/off switch is mounted on the rear panel adjacent to a fused IEC mains inlet. Enclosed in a robust metal case with a durable powder coated finish.
