N7622C Signal Studio for Toolkit

Easily Download Waveform Files

The Keysight Technologies, Inc. N7622B Signal Studio for Toolkit is a free software utility for Keysight vector signal generators that downloads and plays back custom I/Q waveforms. I/Q waveforms created in common development environments, such as MATLAB and C++, are automatically translated into the proper file format for the target baseband generator and then downloaded for playback. Signal Studio for Toolkit features an easy-to-use graphical interface to control the entire waveform download and playback process.

Download Custom Waveform Files at No Charge

Creating custom waveforms using tools such as MATLAB or C++ then downloading them to an ARB, which converts them to I/Q signals, is a typical practice. The base functionality of Signal Studio for Toolkit provides a free, easy-to-use graphical user interface to control the entire downloading process from one location.

Marker Capability

The software enables up to four markers to be easily added to the waveform for use as trigger signals or in controlling advanced features of the signal generator, such as the burst modulator. Additional features such as waveform scaling can be used to achieve the best dynamic range of the digital-to-analog converters (DACs).

Change the Data Sample Rate

Toolkit allows you to change the data sample rate from the user interface and enables downloading and playback of all custom waveform files without time-consuming con- versions. The software automatically re-samples the data provided with the supplied waveform sample rate. The re-sampling is accomplished using an FFT and an IFFT. The process is designed to preserve the waveform shape of the provided data and minimize distortion at the end points.

Application Programming Interface (API)

The N7622C software supports both the Microsoft .NET and COM application programing interfaces (API), which means you can develop your own custom user interface. It enables systematic and efficient configuration of custom waveforms.

Creating a custom interface allows programmatic setting of signal parameters by importing custom data sets or using programming loops and mathematical functions rather than manually entering data in the Signal Studio graphical user interface. The entire signal configuration and playback process can be easily automated in your own programing environment using the API. The API’s built-in Help System provides information and programming examples to assist you in creating your custom interface.
