Instek GFG-8219A Function Generator

  • Frequency Range: 0.3Hz - 3MHz
  • Waveforms:Sine, Triangle, Square, Ramp, TTL and CMOS Output
  • External Voltage Controlled Frequency (VCF) Function
  • Duty Cycle Controlled with Signal Inversion Capability
  • Variable DC Offset Control
  • Two-Step (-20dB x 2) and Variable Attenuator
  • Built-in 6 Digit Counter with INT./EXT. Function up to 150MHz / High Resolution
  • INT/EXT AM/FM Modulation
  • LIN/LOG Sweep Mode
  • GCV Output for Synchronization


The Instek GFG-8219A Function Generator as part of the GFG-82XX series are stable low distortion instruments which generate signals in the frequency range up to 5MHz. Typical applications include a wide range of audio response testing applications, vibration testing, servo system evaluation, ultra sound applications, and etc.

These instruments include the following features: logarithmic and linear sweep capabilities, together with a built in frequency counter. The sweep capability simplifies the task of finding resonant points of speakers, filter networks and other networks/structures. An oscilloscope may be connected to this instrument for the response to be displayed. The counter can be switched to measure and display the frequency of an external signal up to 150MHz.

InstraView™ Equipment Inspection

Buying used equipment doesn't always have to be a shot in the dark. We know there are plenty of differences when it comes to used equipment and quite often, choosing between different pieces is difficult, especially when the equipment is not sitting right in front of you.

Well, what if you were able to see a piece of equipment before you purchased it? Not just a picture from the manufacturer's website, but the actual piece of equipment you would receive.
With InstraView™, we move you one step closer to inspecting the equipment you're interested in without having to wait for the equipment to show up at your door.

InstraView™ works in your web browser and allows you to view the actual piece of equipment you're interested in before purchasing. You can zoom in close to see the labels with the serial number or zoom out to see the overall condition of the equipment.

It's like having the store come to you!
