Standard Accessories:
Custom IQ Signal Generation Option
The Custom IQ option enables user-defined I/Q waveform playback on compatible Siglent RF and vector signal generators. This option allows engineers to upload and generate custom baseband I/Q data, making it ideal for advanced RF testing, proprietary modulation schemes, and experimental communication systems.
With Custom IQ enabled, the signal generator becomes a flexible software-defined RF source, capable of reproducing virtually any digitally modulated signal within the bandwidth and performance limits of the instrument.
Key Features of the Custom IQ Option
-
Enables custom I/Q waveform playback
-
Supports user-generated baseband I/Q data
-
Ideal for proprietary and non-standard modulation schemes
-
Compatible with external waveform design tools
-
High-fidelity RF playback using Siglent hardware
-
Software license activation – no additional hardware required
Full Control Over Your I/Q Waveforms
The Custom IQ option allows users to import externally generated I/Q data files, created using tools such as MATLAB®, Python, or other signal-processing software. These waveforms can then be converted to RF signals directly by the signal generator, ensuring precise and repeatable playback.
This is particularly useful for testing non-standard protocols, custom modulation formats, interference scenarios, and edge-case signal conditions that are not covered by standard modulation options.
Ideal for Advanced RF Development and Research
The Custom IQ option is widely used in wireless R&D, defense and aerospace research, academic environments, and advanced product validation. It provides maximum flexibility for engineers who need complete control over the transmitted signal structure without being limited to predefined modulation standards.
When combined with Siglent signal generators and optional software such as SigIQPro, Custom IQ enables a powerful and scalable RF test platform.
Siglent ToolKit Option – Advanced RF Test Utilities
The Siglent ToolKit option is a productivity-enhancing software package that adds a set of advanced RF test and measurement utilities to compatible Siglent signal generators. Designed to simplify daily test tasks, the ToolKit option helps engineers configure, verify, and automate RF signal generation more efficiently.
This option is ideal for users who want faster setup, improved workflow, and greater control during RF development, validation, and production testing.
Practical Tools for Efficient RF Signal Generation
With the ToolKit option enabled, users gain access to additional built-in utilities that streamline common RF test procedures. These tools reduce the need for external equipment or manual calculations, saving time and minimizing setup errors in the lab or production environment.
The ToolKit option is especially valuable when signal generators are used in automated test systems, remote control setups, or repetitive measurement tasks.
Key Features of the ToolKit Option
-
Adds advanced RF utility functions to the signal generator
-
Improves workflow efficiency and test repeatability
-
Designed for daily RF development and production use
-
Seamless integration with existing Siglent hardware
-
Software license activation – no additional hardware required
Ideal for R&D, Production, and Automated Testing
The ToolKit option is well suited for RF R&D laboratories, manufacturing test lines, and educational environments where speed, consistency, and ease of use are critical. By extending the built-in functionality of the signal generator, ToolKit helps engineers focus on measurements rather than instrument configuration.
When combined with other Siglent software options, such as digital modulation or Custom IQ capabilities, the ToolKit option contributes to a powerful and flexible RF test platform.
