GW Instek GFG-8250A Analog Function Generator
Features
- Frequency Range: 0.5Hz ~ 5MHz
- Waveforms: Sine, Triangle, Square,Ramp, TTL and CMOS Output
- External Voltage Controlled Frequency (VCF) Function
- Two-Steps (-20dBx2) and Variable Attenuator
- Built-In 6 Digits Counter with INT/EXT Function up to 150MHz
The GFG-8200A product family offers a complete solution in generating signals at the 3MHz/5MHz ranges. All models are embedded with standard functions such as TTL/CMOS/Ramp output, External Voltage Controlled Frequency (VCF), and built-in 6-digit counter (except for GFG-8215A).
Further versatility of Logarithmic and Linear sweep is added into GFG-8255A/8219A/8217A, while GCV output feature and AM/FM modulation are available in GFG-8255A/8219A. All these integrated functions and user-friendly operations of the GFG-8200A series are made to accommodate the applications in audio response testing, vibration testing, servo system evaluation, ultra sound application, etc.
