Description:A small & portable function generator--a piece of test equipment often lacking on most hobbyist's test benches.  This product also doubles as a servo controller!Most important functions and capabilities are detailed in the manual.As always, we are glad to provide both pre- and post-purchase support, so if you happen to have any questions just contact us!Specifications:Frequency range: 0 - 200KHz (Sine)Frequency resolution: 1HzPeriod resolution: 1msAmplitude range: 0 - 10V peak-to-peakOffset range: -5V - +5VMemory depth: 256 bytesSample rate: 2.5MspsOutput impedance: 50 ohmPower supply voltage: DC 15VCurrent consumption: < 150mA (without loading)Dimension: 155 X 55 X 30 mmNet weight: 100 gramsFeatures:- Generates continuous waveforms of Sine, Square, Triangle, Ramp (up and down), and Staircase (up and down)- Generates servo test/control signals in micro-second resolution with user programmable pulse width, amplitude, and cycle- Setting of frequency (or period), amplitude, and offset is done digitally, not with often-finicky knobs- Frequency (period), amplitude, and offset can be incrementally adjusted with rotary encoder- Settings are remembered even after power-down.- Can be used as an adjustable DC voltage source by setting amplitude to 0
