About This Instrument
The Vartech SGDA-30M is a dual-channel DDS function generator with 30 MHz sine output (25 MHz square and triangle, 6 MHz pulse/TTL/arbitrary), 266 MSa/s sampling rate and 14-bit resolution. A 2.4-inch TFT colour LCD displays all parameters. Waveforms include sine, square, pulse, triangle, CMOS, DC level, partial/half/full wave, staircase waves, noise, exponential, Lorenz and 60 built-in arbitrary waveforms. DC offset, linear/log sweep, burst and settings store/recall are provided. A multifunction frequency counter covers 1 Hz to 100 MHz. USB and TTL external interface. Power via DC 5V adaptor (220V AC supplied).
