Spectrum Analyzer Vs Oscilloscope

Spectrum analyzer vs oscilloscope. To summarize if it is great bandwidth you require the spectrum analyzer is better. Without the spectrum analyzer it would not have been possible to break the elements of a signal or to credibly gauge a circuit s performance. This fact sheet compares the performance of the 3 series mdo s built in spectrum analyzer to common oscilloscope fft performance. The oscilloscope on the other hand is used to get detailed information about the timing of several detected signals as the spectrum analyzer reveals frequency the primary job of the oscilloscope is to find the relative delay of timings between two separate signals.

The signal analyzer is a spectrum analyzer that includes digital signal processing dsp. Also unlike the spectrum analyzer the oscilloscope has a wide open front end no filtering and more broadband noise can find its way into in the measurement. The oscilloscope is oriented on a shape of signal in the time domain sa is oriented on capturing certain shapes in the frequency domain. The spectrum analyzer has two axes frequency and amplitude and resembles an oscilloscope in its layout.

This enhanced processing mode is the basis for time domain measurement and display in today s spectrum analyzer. For versatility and user friendly operation the oscilloscope is the right choice. Time of the signal while the spectrum analyzer plots the amplitude vs. The digital oscilloscope also has added dsp and gains much higher bandwidths.

4 oscilloscope and spectrum analyzer have different ways to set up triggers. So the oscilloscope plots the amplitude vs. Their differences in the. Both oscilloscopes and spectrum analyzers are necessary and have their various applications for different fields.

Both of these tools are very important in any signal analysis application. While an oscilloscope displays a signal with respect to time a spectrum analyzer shows it with respect to frequency. This article explains the difference between oscilloscope and spectrum analyzer using examples. A typical high end spectrum analyzer has a 165 mhz bandwidth while a 2 ghz oscilloscope s bandwidth is greater by a factor of over 20.

Frequency of the signal. But this is the chief difference. Typical spectrum analyzers sample data at 14 bits where typical oscilloscopes are 8 bit devices. 5 the oscilloscope cannot demodulate signals a spectrum analyzer usually can because it is virtually an sdr receiver.
