RF and microwave network analysers are used to characterise the performance of components such as filters, amplifiers, antennas, cables and RF modules. Vector network analysers (VNAs), in particular, measure S-parameters, insertion loss, return loss and impedance, helping engineers evaluate component and system performance across different frequency ranges.

Electro Rent provides access to network analyzers from leading manufacturers including Keysight, Rohde & Schwarz, and Anritsu for engineering teams across Malaysia, Singapore, and the wider Asia region. These instruments support applications across R&D, design validation, manufacturing, and field testing applications.

Flexible Network Analyzer Rental

Selecting the right network analyzer depends on several factors, including frequency range, number of ports, dynamic range, measurement speed and the type of device under test. Our team can help you compare suitable models and explore network analyzer rental options based on your technical requirements and project duration.

Renting a network analyzer can be especially useful for short-term development, additional test capacity, or projects requiring higher-frequency capabilities than your existing equipment.

Certified Used Network Analyzers and Pricing

For longer-term requirements, certified used network analyzers can provide a cost-effective alternative to purchasing new equipment. Network analyzer prices vary depending on frequency range, configuration, performance specifications, and condition.

Electro Rent helps customers across Malaysia, Singapore, and Asia compare rental and certified pre-owned options based on your application and budget.

Frequently Asked Questions

1. What are network analyzers used for? 
   Network analyzers are a type of test equipment for measuring the network parameters of electrical networks. Radio frequency network analyzers can be used across both radio frequencies and microwave frequencies. Used to identify and solve network communication problems and optimise networks, these test instruments have a range of uses and applications in telecommunications, aerospace and defence, automotive, and a range of other industries.
2. How do network analyzers work? 
   Network analyzers are normally made up of four main components: a signal generator, a test set, a receiver or receivers, and a display. Usually, they have two test ports, allowing the measurement of four S-parameters, although instruments are available with more ports. The analyzer generates a signal, then the test set routes this known signal to the device under test and the receiver(s) make the measurements of the ratios between input and output signals. Then, this signal is formatted visually on the display for the user to read.  
   
   Most modern network analyzers are vector network analyzers (VNAs). These offer better performance because vector network analysis measures both magnitude and phase as well as being able to make time-domain measurements, match complex impedances, and more. In contrast, old network analyzers known as scalar network analyzers (SNAs) were only able to measure magnitude.
3. What are the different types of network analyzers? 
   There are a few different types of RF and microwave network analyzers that measure networks' parameters in different ways.  
   • Vector network analyzers (VNAs) are a common type of network analyzer and are sometimes referred to as automatic network analyzers or gain-phase meters. These measure both the amplitude response and phase of the device under test (DUT); the measurement of phase allows for a better characterisation of the network and device. VNAs do this by generating a signal and taking measurements of the transmitted and reflected waves through the device under test. Most of the time, when people refer to network analyzers, they are talking about VNAs.  
   • Scalar network analyzers (SNAs) are a less often used type of network analyzer that can only measure the amplitude properties of the device that is being tested. This means that it is simpler and can measure fewer parameters than a vector network analyzer. They are often cheaper than VNAs due to their more limited performance.  
   • Large Signal Network Analyzers (LSNAs) are less common and are used to analyse networks under large signal conditions.
4. What's the difference between a network analyzer and a spectrum analyzer? 
   Both electrical testing instruments designed for the measurement and analysis of radio and microwave frequencies, there are some key differences between network and spectrum analyzers. Firstly, the measurements they make are different. While a spectrum analyzer is for the measurement of existing signals in the frequency domain, a network analyzer generates a signal and measures the response in order to test the network.  
   
   Moreover, microwave and RF network analyzers are more accurate in their measurements than spectrum analyzers, using vector-error correction. Meanwhile, spectrum analyzers tend to have a wider range of intermediate frequency (IF) bandwidths available than network analysis tools.

5. What frequency range and dynamic range should I look for in a network analyzer?
   The necessary range of frequencies will depend on your particular application. Low frequency RF testing to high frequency millimeter-wave (mmWave) applications such as 5G, radar, and satellite systems. At the same time, a wide dynamic range is a must for measuring small signals in the presence of large signals particularly when characterizing high performance devices.
6. How many ports does a network analyzer need for my application?
   Standard VNAs come with 2 ports, but some applications like multi-port devices, antennas, or balanced component testing may require 4-port or more. Multi-port analyzers improve test efficiency and reduce switching errors.
7. Do you provide calibration kits or electronic calibration (ECal) support with the analyzer?
   Yes, Electro Rent offers mechanical and electronic calibration kits (ECal) to ensure accurate measurements. These can also be rented or purchased with the analyzer depending on your setup needs.
8. Is time-domain or mixed-mode analysis supported on your VNAs?
   Many modern VNAs offer time-domain transform functions for TDR-like cable testing and mixed-mode S-parameter measurements for differential signal analysis, especially useful in high-speed digital applications.
9. Can I automate measurements or integrate the analyzer into my test system?
   Yes. Most VNAs have SCPI command sets, LabVIEW drivers, and PC connectivity to allow for remote control and automation of test systems and easy integration into the most complex of test benches and production systems.
10. Why purchase a used network analyzer? 
    For network analysis on a budget, purchasing a certified pre-owned network analyzer is one of the most cost-effective options. We carefully source the highest quality used network analyzers from world leading brands such as Keysight Technologies and Rohde & Schwarz. Each instrument undergoes our rigorous 23-step certification process and calibration (calibration certificates are included).
