Spectrum Analyzer Basics Application Note

Posted on 2016/12/08 by George


Spectrum analyzers are useful tools for broadcast monitoring, RF component testing, and EMI troubleshooting. There are a number of common adjustments available with many modern analyers that can optimize performance for a particular application. In this application note, we will introduce resolution bandwidth (RBW) and video bandwidth (VBW) and how they affect measurements.

Resolution Bandwidth (RBW):

Bandwidth is defined as the span of frequencies that are the focus of a particular event. For example, the bandwidth of transmission signal is the span of frequencies that the transmission occupies. The bandwidth of a measurement defines the range of frequencies that were used for the measurement.
In spectrum analysis, the resolution bandwidth (RBW) is defined as the frequency span of the final filter that is applied to the input signal. Smaller RBWs provide finer frequency resolution and the ability to differentiate signals that have frequencies that are closer together.
Why not use the smallest RBW setting for all measurements?
Sweep Time.
Sweep time is the length of time it takes to sweep the detector from the start to the stop frequency. Here is the equation governing the sweep speed:
In the formula above, the meaning of the first factor is the number of frequency selections under SPAN, each step is 1 / k of RBW, to ensure the accuracy of amplitude measurement. The second factor means that each selection The time required depends on the smaller value between RBW and video bandwidth (VBW). Usually when we do not focus on noise, the VBW can be set to a value
greater than or equal to RBW.

Electromagnetic Compliance: Troubleshooting with Near-Field and Current Probes

Posted on 2016/11/14 by George


Electromagnetic interference (EMI) can cause a host of problems, especially when developing a product or attempting to pass mandatory electromagnetic compliance (EMC) tests. Garbled displays, bad data, or complete malfunctions can occur when a designis effected by EMI. To minimize the effects of interference, government agencies like the Federal Communications Commission (FCC) in North America create and enforce standards that setlimits on the EM output of a product type.Testing to the specifications is commonly referred to as Electromagnetic Compliance (EMC) testing. 

Many EMC test failures stem from the interaction of unintentional radio frequency (RF) emissions with a circuit or element within the design itself. The electric and magnetic fields that cause this interference are not visible to the unaided eye, which can present complications when trying to isolate the root cause and minimize the effects of the EMI. 

• What is causing the issue?
• Where is the source of the signal or energy causing the radiation?
• How can I fix it?

10 myths about WiFi interference

Posted on 2016/09/09 by George

Growing ubiquity of wireless devices combined with the advent of mobility applications requires businesses to be diligent in managing inference throughout their deployments. The many wireless technologies and commonplace electric devices already in use and newly emerging impede wireless performance.

WiFi interference can be a major inhibitor to wireless performance, creating security vulnerabilities and wireless network instability.

This blog post exposes the top 10 most pervasive myths around wireless interference.

  1. The only interference problems are from other 802.11 networks.

    There are a tremendous number of 802.11 devices out there. It is true that the other 802.11 networks can cause interference with your network. This type of interference is known as co-channel and adjacent channel interference. But since other 802.11 devices follow the same protocol, they tend to work cooperatively-that is, two access points on the same channel will share the channel capacity.
    In reality, the many other types of devices emitting in the unlicensed band dwarf the number of 802.11 devices. These devices include microwave ovens, cordless phones, Bluetooth devices, wireless video cameras, outdoor microwave links, wireless game controllers, Zigbee devices, fluorescent lights, WiMAX, and so on. Even bad electrical connections can cause broad RF spectrum emissions. These non-802.11 types of interference typically don't work cooperatively with 802.11 devices, and can cause significant loss of throughput. In addition, they can cause secondary effects such as rate back-off, in which retransmissions caused by interference trick the 802.11 devices into thinking that they should use lower data rates than appropriate.
    Summary: The unlicensed band is an experiment by the FCC in unregulated spectrum sharing. The experiment has been a great success so far, but there are significant challenges posed by RF interference that need to be given proper attention.
