Tektronix AFG3251C Arbitrary Function Generator

The AFG3251C is a fast and enhanced arbitrary function generator from Tektronix. This model provides multiple modulation types, including amplitude, frequency, and phase modulation. It also offers frequency shift keying (FSK) and pulse width modulation (PWM). The AFG3251C offers AM, FM, and PM for all carrier waveforms, except pulse, noise, and DC. The AFG3251C arbitrary function generator makes use of internal and external sources. This model offers internal modulating waveform for sine, square, ramp, noise, and ARB. It has the internal modulating frequency range of 2 MHz to 50.00 kHz.

The Tektronix AFG3251C arbitrary function generator is helpful for education purposes. It has the capability to offer sweep and burst features. The AFG3251C also offers pulse width modulation for pulse carrier waveforms. It has the deviation of 0% to 50.0% of the pulse period. It offers FM peak deviation of 120 MHz for the sine wave. It has 60 MHz FM peak deviation for the square wave and ARB. The AFG3251C comes with an FM peak deviation of 1.2 MHz for other waveforms. 

The AFG3251C arbitrary function generator comes with two keys for the frequency shift key. This model has an internal modulating frequency of 2 MHz to 1.000 MHz for FSK. The AFG3251C offers a sweep frequency of 240 MHz for sine waves. The instrument comes with several accessories, including a power cord, USB cable, and CD-ROM. A quick-start guide and programming manual are also available if the user chooses to purchase them. The AFG3251C arbitrary function generator weighs around 4.5 kilograms.
