— Vartech® Function Generators
15 MHz DDS with 266 MSa/s, 2.4-inch TFT and 60 arbitrary waveforms — same platform as the 30M at a more accessible frequency.
Authorised Dealer The Vartech SGDA-15M is a dual-channel DDS function generator sharing the proven SGDA-30M platform with 15 MHz sine, square and triangle output (6 MHz pulse/TTL/arbitrary), 266 MSa/s, 14-bit resolution and a 2.4-inch TFT LCD. All waveforms, 60 arbitrary waveforms, the 1 Hz to 100 MHz frequency counter, DC offset, sweep and burst functions are identical to the SGDA-30M.
