Features:The display interface uses a 2.4-inch TFT color LCD screen, making operation more intuitive and convenient. The instrument adopt the Direct Digital Synthesizer (DDS) technology and provide stable, precise, pure and low distortion signals. Abundant shortcut keys and graphical user interface simplifies every operation, which makes it easy to operate. Surface mounting technology improves interference immunity and operational life span. The instrument uses 14-bit high D/A converter chip (5Vpp output quantization error is less than 1mV), 250MSa/s sample rate, 14bits vertical resolution. Various modulation types: AM, FM, PM, ASK, FSK and PSK modulations. Sweep Function: It can sweep 4 properties of signals including frequency, amplitude, offset and duty cycle; It has Linear and Logarithm two sweep types; 0.01S~999.99S sweep time; Up, Down and roundtrip sweep directions. VCO Function (Voltage Control Output): Can be achieved by an external input signal: voltage controlling frequency, voltage controlling amplitude, voltage controlling offset, voltage controlling duty cycle and PWM modulations. 100M Frequency meter function: It can measure frequency, period, pulse width and duty cycle. Max. frequency workable is 100MHz and Min. frequency workable is 0.01 Hz. Counter Function: It has 2 coupling measure modes including DC coupling and AC coupling. This design can solve inaccuracy problem of AC coupling. Output short-circuit protection: All channels can work more than 60 seconds when the load is short-circuited.
