About vector signal generators
Vector signal generators are devices used to create signals simulating real-world RF signals for testing communications equipment. In contrast to regular signal generators which produce simple waveforms such as sine waves, vector signal generators can generate more complex RF signals with amplitude and phase modulation.
Uses of vector signal generators
Vector signal generators, or digital signal generators as they are sometimes known, are designed for testing modern digital communications systems where traditional analog signal generators are no longer appropriate. Vector signal generators are used to troubleshoot and test wireless communication systems such as Wi-Fi, Bluetooth, and cellular devices. These devices are used in a range of industries such as telecommunications, aerospace and defence, and R&D.
What's the difference between a signal generator and a vector signal generator?
In comparison to general-purpose signal generators, vector signal generators have more advanced and complex capabilities. For example, while a regular signal generator only produces simple waveforms, vector signal generators can create electrical signals with amplitude and phase modulation and can vary the data rate of the signals.
Regular signal generators may offer some form of modulation such as AM or FM, but these capabilities are somewhat limited. This is why for some testing applications, engineers will instead choose a vector signal generator which can vary the modulation format of the signals by changing the type of modulation used such as QAM and QPSK, or by changing the bit rate of signal generation.
These advanced capabilities mean that VSGs are often more expensive than regular signal generators, which is why buying Certified Pre-Owned or renting a VSG is a great choice. Alternatively, you can browse our full range of RF and microwave signal generators.
What should I consider when choosing a vector signal generator?
When selecting a vector signal generator, it's important to make sure it has the capabilities to fit your application. Firstly, the signal generator's frequency range should cover the range of frequencies of your device under test. Secondly, it should support the types of modulation that you need to simulate real-world conditions that your device may encounter.
The accuracy of the generator and the amount of phase noise is another key consideration. The higher the accuracy, the more expensive the VSG tends to be, which is why rental or buying used generators can be a great solution. You also need to choose a generator that can generate signals at the data rate your communication system operates at. Finally, the output power in dBm is an important consideration – if the power output is too low you will not be able to effectively test the device but if it is too high it may damage the DUT.
In addition to these technical considerations, your choice of VSG will likely also depend on the model's price and ease-of-use.
What are the best vector signal generators?
Our independent experts have carefully selected used and new vector signal generators from industry-leading manufacturers such as Rohde & Schwarz, Keysight Technologies, Anritsu, and Spectracom. While the best RF signal generator for you will depend on your requirements and budget, you can be sure that the range we stock offers impressive and accurate performance.
What's the typical frequency range of a vector signal generator?
While the frequency range of vector signal generators can vary significantly between models, the majority of regular VSGs have a range of frequencies between several GHz to tens of GHz.
What phase noise is typically present in VSGs?
Vector signal generators tend to have low phase noise, although the amount of unwanted phase noise can vary between different models and manufacturers. For example, the Keysight Technologies E8267D offers an impressive -120 dBc / Hz phase noise at a 10 kHz offset for a 10 GHz signal.
Why rent a vector signal generator?
For short and medium-term projects, renting a vector signal generator can be an ideal way to access top quality equipment without expensive purchase and ownership costs. RF vector signal generator rental includes rapid delivery and expert support, meaning you never have to worry about maintenance or issues with your signal generator. We offer flexible rental terms from one week to low-cost plans over multiple years, allowing you to pick the option that suits you. Plus, rapid worldwide delivery means you can get started with your project quickly. We also offer low-cost, long-term rental plans that make renal a money saving alternative to purchase for ongoing use.
Why buy a used vector signal generator?
Due to their advanced capabilities and features, vector signal generators tend to cost more than regular signal generators, and purchasing the right one for your application can be rather expensive. A more cost-effective path to ownership is buying a used VSG. Our Certified Pre-Owned vector signal generators are all carefully selected by the team and rigorously tested and calibrated in a 23-step calibration process. With a 14-day money-back guarantee if you are not satisfied with the generator and a one-year warranty, purchasing used can be a great way to access high-performance VSG without the high upfront cost.
