  • Welcome to the solution module on Handheld signal generator. This training module introduces basic working principle and its different components involved
  • An electronic test instrument that delivers a sinusoidal output at an accurately calibrated frequency that may be anywhere from the audio to the microwave range There are many different types of signal generators, with different purposes and applications (and at varying levels of expense) signal generators have been embedded hardware units
  • Signal generators can be divided into two types depending on their memory options and clocking characteristics. These two categories are function generators and arbitrary waveform generators (AWGs).  Signal generators use the synchronization and memory core (SMC) architecture to provide a common interface between a device's onboard memory. The SMC also offers many advanced marker and trigger features for synchronization with other instruments
  • The AWG’s playback scheme can be thought of as “sampling in reverse.” It acquires a waveform by digitizing the analog signal’s voltage value at a succession of points in time, with the frequency of the sampling being determined by the user-selected clock rate. The resulting samples end up in a memory. The AWG starts with a waveform already in its memory. The waveform occupies a designated number of memory locations. With every clock cycle, the instrument outputs another waveform sample from the memory The AFG maintains a fixed system clock frequency. The 360 degrees of a waveform cycle are spread across the full number of waveform samples, and the DDS section automatically determines the phase increments based on the waveform length and the frequency selected by the user.
  • Signal Generators produce complex RF signals utilizing one of two primary up-conversion techniques: heterodyne or direct. The heterodyne approach employs digital up-conversion to create a digital intermediate frequency (IF) which is converted into the RF domain through the use of a single Digital to Analog Converter (DAC) and a single or multi-stage mixer. The direct conversion architecture is often found in modern Vector Signal Generators because of the simplicity and cost effectiveness of design. Two DACs are utilized to create analog I and Q signals which are then mixed with a local oscillator to product two signals that are 90 degrees out of phase. These translated baseband signals are then summed to produce the RF signal.
  • The complete signal generator block consist of sub systems like DSP processor, baseband block which contain onboard interpolation filters (FIR) that are configurable in either Low-Pass or High-Pass mode, RF up conversion, Power management block based on a computer architecture, leveraging display, interface, and power management functions from the high-volume PC market
  • The TMS320C6472 device is a Texas Instruments next-generation fixed-point digital signal processor (DSP) targeting high-performance computing applications, including high-end industrial, mission-critical, high-end image and video, communication, media gateways, and remote access servers. This device was designed with these applications in mind. A common key requirement of these applications is the availability of large on-chip memories to handle vast amounts of data during processing. With 768K-Byte of shared RAM and 608K-Byte local L2 RAM per C64x+ Megamodule, the TMS320C6472 device can eliminate the need for external memory, thereby reducing system power dissipation and system cost and optimizing board density.

    • 3. What is Signal Generator
      • A signal generator, also known variously as function generator, pitch generator, arbitrary waveform generator, digital pattern generator or frequency generator.
      • It is an electronic device that generates repeating or non-repeating electronic signals (in either the analog or digital domains).
      • An electronic test instrument that delivers a sinusoidal output at an accurately calibrated frequency that may be anywhere from the audio to the microwave range
      • The frequency and the amplitude are adjustable over a wide range. The oscillator must have excellent frequency stability, and its amplitude must remain constant over the tuning range.
      • The Wien-bridge oscillator is commonly used for frequencies up to about 200 kHz. For a radio-frequency signal generator up to about 200 MHz, a resonant circuit oscillator is used (such as a tuned-plate tuned-grid, Hartley, or Colpitts). Beyond this range VHF and microwave oscillators are used
    • 4. Types of Signal Generators
      • Function Generators
      • Function generators are designed to generate periodic waveforms at precise frequencies.
      • They typically use a clocking mechanism known as direct digital synthesis (DDS) to generate precise frequencies of better than 1 µHz of precision
      • Arbitrary Waveform Generators
      • Designed to generate large and often complex waveforms, they use deep onboard memory and sophisticated clocking mechanisms
      • AWGs are capable of advanced linking, looping, and scripting of waveforms for even more complex sequences.

    • 7. Sub System Component
      • Digital Signal Processing
      • T he DSP is capable of handling the performance requirements of the signal processing algorithms needed for such a function and at the same time provides the flexibility of changing system functionality and characteristics of the generated signal.
      • Baseband / IF
      • High-speed Digital to Analog Converters with superior linearity, noise, crosstalk, and PLL phase noise performance are critical to the overall performance of the Generator
      • RF Up-conversion
      • The local oscillator provides a programmable, low-phase noise signal to be mixed with the analog I and Q signals created by the DACs.
      • Power Management and Conversion
      • Signal Generators exist in various form factors such as bench, portable, and modular (or backplane based). The form factor plays a large role in determining the power management requirements of the instrument
