2 MHz Sweep Function Generator (VPL-FG2M)
The Sweep function generator offers wide functional capability at a modest price. This compact unit has ranges from
0.02Hz to 2 MHz. Range & function selection adds convenience to versatility. Added features not found in function
generators of this price range are voltage control and a separate pulse output suitable for synchronization or driving TTL logic circuits.The instrument is designed using easily available components resulting in ease of serviceability. Greater emphasis has been put on ruggedness & reliability with the use of single pcb for complete circuit. The lower frequencies are of special interest to servo manufacturers. Offers sine, square, triangle functions upto 2MHz.
