Instek AFG-3051 50MHz Arbitrary Function Generator

Instek AFG-3051 – 50MHz Arbitrary Function Generator

Wide Frequency Range from 1uHZ to 80/50MHz

The AFG-3000 series arbitrary waveform/ function generator employs direct digital synthesis (DDS) technology to generate and output a variety of stable and precise waveforms. The frequency operates at up to 80MHz (AFG-3081) or 50MHz (AFG-3051), with a minimum resolution of 1uHz for the entire frequency range. The built-in standard waveforms include sine, square, triangle, ramp, pulse, noise and other types of waveforms.
 

High 200MSa/s Sampling Rate

The profile of arbitrary waveform is composed of a series of data. The frequency of the arbitrary waveform is derived from the sampling rate divided by the number of points constructing a complete waveform, i.e. frequency = sampling rate / the number of points in a waveform. Based on the above, the higher the sampling rate, the higher the arbitrary waveform frequency can be available.

A Sine waveform composed of 100 points waveform data can have a 2MHz frequency with 200MSa/s sampling rate, but can only have 1.25MHz frequency with 125Msa/s sampling rate and 0.5MHz frequency with 50M sampling rate. AFG-3000, possessing a sampling rate of 200Msa/s, can generate a waveform up to 100MHz for a simple waveform composed of 2 points of data.
 

16-Bit Amplitude Resolution

The 16 bit amplitude resolution can display smooth waveforms, while a lower bit resolution will display jagged or less smooth waveforms. For example, if 10V is divided into 10,000 equal parts, each part would have a resolution of 1mV. When using a 16 bit resolution, the smallest possible bit resolution is 0.15mV (from 10V). With 16 bit resolution, the 10,000 parts will appear to be a smooth straight line, while the bit resolution of 12 bit would be 2.4mV, greater than the 1mV needed. In this case the straight line would appear like a ladder.
 

Output From any Section of 1M-Point-Long Waveforms

The AFG-3000 Series provides 10 sets of memory for user save and recall applications. Each set of memory is able to store a set of front panel setting and a set of 1M-point arbitrary waveform data. With 1M long memory, AFG-3000 can store more complex waveforms consisted of more data. Further more, any section of waveform within this 1M memory can be edited or output independently. This is a unique feature allowing more flexibility for user to do waveform storage and extraction.

Easy Operation and Flexible Arbitrary Waveform Editing

The AFG-3000 presents four ways to generate custom arbitrary waveforms from direct front panel operation, PC software, a CSV file loading, and GDS-2000 series oscilloscope input.

AFG-3000 supports CSV file editing for arbitrary waveform generation. The CSV file can be created in many ways, including using EXCEL spreadsheet, PC client software, front panel editing or math computing software. The computing result of math software, Octave for example, can be saved into CSV file. Edited CSV file can be downloaded from either USB flash or PC to AFG-3000 for arbitrary waveform output.

Digital Signal

A PC software for AFG-3000 waveform editing is supported. The software contains not only waveform drawing tools but also a wide variety of waveform editing functions, such as waveform arithmetic operations. The most commonly used waveforms, including Rayleigh, Gaussian, Normal Noise, Pseudo Ternary, Bipolar AMI, Manchester, Differential Manchester, RS-232, and NRZ etc., are available in the library for user to tailor specific waveforms as needed.

Impedence Switch and On- Screen Help

AFG-3000 allows users to select the suitable impedance between 50 ohms and High-Z, ensuring the right impedance compatibility. The built-in On-Screen Help allows users to understand AFG-3000 operations and the definition of each function key.
