Instek GFG-8255A 5MHz Function Generator with Counter, Sweep Mode & AM/FM Modulation

The Function Generator 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.

GFG-8200A Series ADDITIONAL FEATURES

Low distortion waveforms (sine, triangular and square) and ramp signal.
Signal output in seven decade stages, 0.5Hz to 5MHz for GFG-8250A/8255A, 0.3Hz to 3MHz for GFG-8215A/8216A/8217A/8219A.
Adjustable sweep time and sweep width both in linear and logarithmic modes.
Duty cycle control with signal inversion capability.
External Voltage controlled Frequency (VCF).
AM or FM modulation modes with internal or external modulation control.
A second output for TTL or adjustable CMOS pulses.
50 ohm main signal output with DC offset adjustment and 20dB attenuation capability.
Supplied with two BNC test leads and AC power cord set.
