Difference between oscilloscope and spectrum analyzer

With excellent optical spectrum measurement capabilities (high resolution and high speed), operability and maintenance performance, the AQ6375 optical spectrum analyzer will contribute to the performance improvement and spread of near-infrared semiconductor lasers used in laser absorption spectroscopy. The darker areas are those where the frequencies have very low intensities, and the orange and yellow areas represent frequencies that have high intensities in the sound. The difference between spectrum analyzer and network analyzer mainly lies based on the measurement applications as described below. Both spectrum analyzer and network analyzer inside use tuned receivers which operates over same or similar frequency range. Traditionally, the time domain is used to recover the relative timing and phase information required to characterize electrical circuit behavior.

This is similar to an oscilloscope with a 1-bit resolution. difference between spectrum analyzer and network analyzer. domain, by an oscilloscope, or in the frequency domain using a spectrum or signal analyzer. On the other hand, Logic analyzers represent signals in their digital form: a logic 0 or logic 1. Oscilloscopes are best used for evaluating signal integrity and measuring analog circuit performance.

The resulting graph is known as a spectrogram. An oscilloscope allows you to view analog voltages and how they change over time.

Deep optical absorptions appearing in the long wavelength region around 2 m caused by CO2, NOX and H2O are attracting attention in the environmental and medical fields, and thus sensitive measuring equipment by laser absorption spectroscopy using a near infrared semiconductor laser is becoming more popular. The spectrum analyzer above gives us a graph of all the frequencies that are present in a sound recording at a given time. Despite the popularity of desktop optical spectrum analyzers in the telecommunication wavelength region, a large-scale optical spectrum measurement system with a monochromator has commonly been used for measuring the long wavelength region, and so there was a need for a desktop optical spectrum analyzer for long wavelengths. We have developed the AQ6375 grating-based desktop optical spectrum analyzer, which can measure an optical spectrum over a wide wavelength range from 1.2 to 2.4 m with high wavelength resolution at high speed.
