Frequency Resolution

 

 

Frequency resolution is an important specification for applications that measure signals that are close together and need to be distinguished from one other. The IF filter bandwidth is called the resolution bandwidth (RBW) because the shape and bandwidth of the IF filter determines the resolvability between signals. In addition to filter bandwidth, the selectivity, filter type, residual frequency modulation (FM) and noise sidebands are important factors to consider in determining useful frequency resolution.

Spectrum analyzers and signal analyzers display raw, unprocessed signal information such as voltage, power, period, wave shape, sidebands, and frequency. They can provide the user with a clear and precise window into the frequency spectrum. Search by Specification | Learn more about Spectrum Analyzers and Signal Analyzers
Vector network analyzers (VNA) measure the complex transmission and reflection characteristics of two-port devices in the frequency domain. Search by Specification | Learn more about Vector Network Analyzers
Passive filters are implemented using only passive components such as resistors, capacitors and inductors. These filters do not produce any amplification of the input signal. Learn more about Passive Filters
Noise figure meters measure the noise contribution of an amplifier relative to a noise-free amplifier at a reference temperature. For most Ku-band amplifiers, values are expressed in decibels (dB). Learn more about Noise Figure Meters
