Introduction:
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.

It's always good to see that our products are mentioned out in the marketplace. We like it and wanted to share the word. Here is a sampling of some of the posts:
- 5 GHz Real Wave View
- Gadetify Press Release
- Finding a hidden AP (it's like Easter except the egg is rotten). Same environment just using table view
- Featured on Sixty Second Tech - compliments of Gabriel Staples and Abid Jamal.
- Schematics.com checking out WiPry 5x. Thanks to Engr. Neil Edward for the post.
- EEWeb - Germany has a nice write up here. Thanks to Engr. Earl Jaducana. For those that can't read German, review is translated here.

INTRODUCTION:
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?
