상세설명 (Description)

• 80/50MHz의 주파수대역모델 1μHz 고분해등
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.

• 다양한 변조, SWEEP, BURST 기능
The Modulation functions, including AM, FM, FSK and PWM, are provided to cover a broad range of market requirements. A dedicated terminal for the modulating signal output is available in the front panel for modulation monitoring or other control purposes. Either an internal signal or an external signal can be selected to perform the modulation.

FSK is a frequency modulation scheme in which digital information is transmitted through signal frequency variation. The BFSK (binary FSK) modulation, using two frequencies to represent data 1 and 0 respectively, is commonly applied for Call ID and Remote Metering applications.

PWM is a digital modulation scheme that can be used to adjust the output power level by controlling the pulse width of the driving signal. The examples include the speed control of motor rotation and the luminance control of LED lighting instrument. With the pulse width variation of driving signal, the rotating speed of motor and the luminance of LED will change accordingly. wave

The Sweep function supports three trigger modes of INT, EXT and manual, and two sweep modes of LOG and LIN. Each time a sweep signal is perceived, the function generator will start to sweep through the user-defined frequency range by the frequency variation of either Log curve or Linear curve. sweep

The Burst function supports two modes of Gate and N Cycle. To run burst function, the burst repetitive rate has to be set first, then the time duration of each burst has to be defined under Gate mode, or the number of the waveform cycles in each burst has to be set under N Cycle mode. Under both Gate mode and N Cycle mode, the burst waveform polarity and phase can be controlled.

• 200MSa/s의 고속 샘플링 및 16비트 진폭 분해능

The profile of arbitrary waveform is composed of a series of data. The frequency of arbitrary waveform is derived from 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 is able to 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, is able to generate a waveform up to 100MHz for a simple waveform composed of 2 points of data.

• 1M포인트의 긴메모리

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.

• 쉬운 조작과 유연한 임의 파형 편집
CONTENT
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.

ㅁFront Panel Operation
Everything from waveform editing, I/O configuring, and panel setting storage and recall can be completed directly through front panel operation. Front panel operation allows users to edit arbitrary waveform, which is correspondingly updated on the screen, a feature of "What You See is What You Get".

ㅁCSV file uploading
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.

ㅁDirect Waveform Reconstruction (DWR) Capability
The AFG-3000 can be directly connected to a GW Instek GDS-2000 Series DSO with USB cable for waveform data download. Under "DSO Link" mode of AFG-3000, the DSO will transfer the captured waveform data from its memory to AFG-3000 for creating a correspondent waveform output.

ㅁArbitrary Waveform Editing PC Software
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.

• 임피던스 스위치 및 온 스크린 도움말
AFG-3000 allows users to select the suitable impedance between 50 ohm and High-Z, ensuring a right impedance compatibility.
The built-in On-Screen Help allows users to understand AFG-3000 operations and the definition of each function key.

• 다양한 통신 인터페이스
The AFG-3000 provides GPIB, RS-232, and USB as standard communication interfaces. AFG-3000 supports IEEE 488.2 protocol and command for users to integrate system or remotely control the instrument.

• 4.3인치 고분해능 LCD 디스플레이
The AFG-3000 is equipped with a 4.3" LCD screen of 480 x 272 resolutions. In addition to displaying all of the settings on the screen, the large graphic display also allows users to observe complete waveforms at a glance.
