This product is a function generator with a frequency range of 0.3Hz to 3MHz. It has sine wave, triangle wave, square wave, ramp wave, TTL and CMOS output functions. In addition, this product also has external voltage controlled frequency (VCF) function, duty cycle control, variable DC offset control, two-step (-20dBx2) and variable attenuator.
The Tenma 72-7710 function generator provides a wide frequency range from 0.3 Hz to 3 MHz and supports six waveforms: sine, triangle, square, ramp, TTL and CMOS. It includes variable DC offset, duty‑cycle control, and a built‑in 6‑digit counter with internal/external operation up to 150 MHz.
Key specifications include >10 Vpp output into 50 Ω, 50 Ω ± 10% input impedance, two‑step –20 dB attenuator, 6‑digit LED display, and low distortion (<1 %). The unit is powered from 115/230 V AC, measures 251 × 91 × 291 mm, and ships with a power cord, instruction manual, and two GTL‑101 accessories.
