Thank you for buying the DVM20FGCN! Please read the manual carefully before bringing this device into service.
This versatile and user-friendly function generator is supplied with a plastic case. The device can produce 7 different
waveforms: sine, square, triangle, positive & negative pulse, positive & negative ramp.
The device is equipped with a function where the frequency is controlled via the input tension (VCF or "voltage-
controlled frequency"). The DVM20FGCN is also equipped with a TTL sync. output. The waveform symmetry is
adjustable and can be inverted. DC level can be adjusted continuously. The frequency counter can display both the
internal and external frequency.
