— Vartech® Function Generators
60 MHz DDS with 275 MSa/s, 2.8-inch colour screen, full modulation, VCO scanning and built-in frequency counter.
Authorised Dealer The Vartech SGDA-60M is a dual-channel DDS function and arbitrary waveform generator with 60 MHz sine output, 275 MSa/s sampling rate, 14-bit resolution and a 2.8-inch colour screen with silicone keys. Square and triangle output covers to 15 MHz. It outputs sine, square, pulse, triangle, ramp, CMOS, DC, half/full wave, step waves, exponential, Lorentz, multisonic, random noise, trapezoidal, sinker pulse and 99 user-defined arbitrary waveforms. Modulation modes include AM, FM, PM, ASK, FSK, PSK and PWM; sweep covers frequency, amplitude and duty with VCO voltage-controlled scanning. A built-in frequency counter is included.
