SystemFlow® is the software interface that is integrated into every Talon® recorder. The software includes the graphical user interface (GUI) that is used to control the recorder, signal analysis tools and an API that allows users to integrate the Talon recorder into a larger system.

The SystemFlow GUI provides intuitive configuration screens for simple setup of the system hardware and allows users to store their settings as profiles. An integrated signal viewer provides a virtual oscilloscope, spectrum analyzer and waterfall display to allow for analysis of signals prior to, during and after recording.

SystemFlow is only available as an integrated component of Pentek’s Talon Recording Systems. It is not available as a standalone product.

SystemFlow Software

SystemFlow Architecture

  • Server/Client Architecture: The SystemFlow architecture provides for easy communication between the recording system Server and the Client.
  • SystemFlow GUI: The SystemFlow architecture features a Windows-based GUI (Graphical User Interface) that provides a simple means to configure and control the system. Custom configurations can be stored as profiles and later loaded when needed, allowing the user to select preconfigured settings with a single click.
  • SystemFlow Signal Viewer: SystemFlow also includes signal viewing and analysis tools that allow the user to monitor the signal prior to, during, and after a recording session. These tools include a virtual oscilloscope and a virtual spectrum analyzer.
  • Server/Client Communication: Server and Client communicate through a standard socket connection. This arrangement enables the Server to provide real-time recording and playback functions that can be controlled from a local or a remote Client. It also allows Client and Server to run on different operating systems.
  • Function Libraries: The function libraries and tools for controlling the recording and playback functions include the Application Programming Interface, the Graphical User Interface and the integrated Signal Viewer.
  • SystemFlow API: The SystemFlow API (Application Programming Interface) allows developers to configure and customize the system interfaces and operation. Source code is supplied for all client API functions. A well-defined set of plugins allows the user to extend server API functions.
  • NTFS File System: The NTFS file management system provides immediate access to the recorded data, thereby eliminating time-consuming data conversion processes required with proprietary file management systems. It also eliminates the need for custom hardware and software platforms where the recorded data may need to be physically transported for conversion.

SystemFlow Block Diagram

SystemFlow Recorder Interface

The SystemFlow GUI displays a block diagram of the system and provides the user with a control interface for the recording system. It includes Configuration, Record, Playback and Status screens, each with intuitive controls and indicators.

The user can easily move between screens to set configuration parameters, control and monitor a recording, play back a recorded signal and monitor board temperature and voltage levels.

SystemFlow Hardware Configuration Interface

The SystemFlow Configure screen provides a simple and intuitive means for setting up the system parameters.

The DDC configuration screen shown here, allows user entries for input source, center frequency, decimation, as well as gate and trigger information. All parameters contain limitchecking and integrated help to provide an easier-to-use out-of-the-box experience.

SystemFlow Hardware Configuration Interface

SystemFlow Signal Viewer

The SystemFlow Signal Viewer includes a virtual oscilloscope and spectrum analyzer for signal monitoring in both the time and frequency domains. It is extremely useful for previewing live inputs prior to recording, and for monitoring signals as they are being recorded to help ensure successful recording sessions. The viewer can also be used to inspect and analyze the recorded files after the recording is complete.

Advanced signal analysis capabilities include automatic calculators for signal amplitude and frequency, second and third harmonic components, THD (total harmonic distortion) and SINAD (signal to noise and distortion). With time and frequency zoom, panning modes and dual, annotated cursors to mark and measure points of interest, the SystemFlow Signal Viewer can often eliminate the need for a separate oscilloscope or spectrum analyzer in the field.

Recording Dataflow

Shown in this diagram is the dataflow during a typical recording session. The Pentek Transceiver Board contains a 2-channel 200 MHz A/D for digitizing two input analog channels. The digitized outputs are downconverted by the two DDCs (Digital Downconverters) and moved on to the PC system memory via the PCI Express interface.

Both the DDCs and the PCIe interface are implemented in the board’s FPGA. Data then moves from the system memory to the Recording System RAID Controller and is then recorded to disk via the SATA interface. DMA controllers conduct all data transfers, bypasssing the CPU for guaranteed real-time operation.

Recording and Playback Dataflow

Playback Dataflow

During a playback session, data stored on disk moves through the SATA interface of the Playback System RAID Controller. From there, data is passed to the PC system memory through the PCIe interface and then to the Pentek Transceiver board through its PCIe interface, all via hardware DMA controllers for real-time operation.

This board also contains DUCs (Digital Upconverters) which upconvert the data to the original IF frequency bands. Two 800 MHz D/As convert the data to analog form and provide signals that are identical to the analog signals that were originally recorded. These can be further analyzed with any Windows-compatible analysis software.

SystemFlow Recording Software

Demo Simulator for Talon Recording Systems

Pentek's SystemFlow Demo Simulator software package simulates the SystemFlow® recording software, which is installed on all Talon® recording systems. You can download and install the free SystemFlow® Simulator to your desktop or laptop PC.

The SystemFlow Simulator allows you to learn how to use the Talon recording system's SystemFlow software interface before you acquire a recorder or while you are waiting for delivery of a Talon recording system. The Simulator can simulate the operating environment of all the different Talon recorder models.

the free SystemFlow Simulator

The Simulator uses the same client-server architecture as every Talon recording system, thereby allowing you to use either the SystemFlow GUI (Graphical User Interface) or SystemFlow API (Application Programming Interface) to control the system. In this way, the Simulator allows you to experience how the system operates exactly as you would experience using an actual system in the field.

The Server is responsible for the real-time data recording, while the Client provides the user interface, used to control and monitor the recorder. The Client is provided as a GUI (Graphical User Interface). The Client issues commands to the Server over a socket connection.

You can download SystemFlow Simulator user's guide which details the installation, configuration and use of the software.

SystemFlow Signal Viewer

The SystemFlow Simulator demonstrates the SystemFlow signal viewer by playing recorded signals to simulate the appearance of live signals being digitized and recorded by a Pentek analog signal recorder. The SystemFlow signal viewer includes a virtual oscilloscope and a virtual spectrum analyzer for signal monitoring in both the time and frequency domains. The oscilloscope and spectrum analyzer are extremely useful for previewing live inputs before recording them and for monitoring signals as they are being recorded.

SystemFlow API

Pentek's SystemFlow API allows you to develop your own User Interface (UI) for controlling your Talon recording system. The API is a C-callable library that allows you to control the recorder from an application interface that you develop. If you want to develop your own UI, the SystemFlow Simulator provides a means of testing your UI before you receive your Talon Recorder. This is very helpful for development programs that are on a tight schedule.

Training Tool

If you want to simply use the standard SystemFlow GUI, the SystemFlow Simulator is helpful for this as well. The Simulator can serve as a training interface, allowing system operators to become comfortable with the Talon recording system before they receive it. The standard SystemFlow GUI provides the user with a control interface for Talon recording systems that includes Configuration, Record, Playback, and Status screens, each with intuitive controls and indicators.

Simulates all Talon Recorders

Talon High-Speed Recording System

The SystemFlow Simulator can be configured to simulate any of the Talon analog or digital recording systems. You can easily switch from one system to another to simulate the different recording systems in the Talon recording system product line. A common user interface and API provides a simple transition from one Talon recorder to the next.

Local and Remote Control

Like every Talon recording system, the Simulator can be controlled locally or remotely via the socket-based client-server architecture. This allows you to set up and test remote control of your recording system before you receive it. In addition, you can also create system profiles that can be saved in the Simulator and then reused in the actual Talon recording system.
