AQ6370D Spectrum Analyzer: Accurate Measurements with DWDM System

With the rapid advancement of 5G networks, optical communication technology has ushered in unprecedented changes. Dense wavelength division multiplexing (DWDM) systems have become the core of modern fiber optic communication networks due to their efficient data transmission capability and spectrum utilization. However, the dense channel distribution and high-speed data transmission in DWDM systems place higher requirements on the optical spectrum analyzer (OSA).

What is the difference between SR, LR, LRM, ER and ZR in 10G optical modules?

SR, LR, LRM, ER and ZR are the more common module types in the 10GIEEE standard, but what is the difference between 10g SR, LR, LRM, ER and ZR? First we need to know what they represent. In fiber optic communication, SR, LR, LRM, ER and ZR are a kind of distance terminology in 10G optical module transmission, SR means short distance, LR means long distance, LRM means length extended multipoint mode, ER means ultra-long distance, and ZR means the longest distance.

N7779C keysight Tunable Laser Source Description

The new N7779C Base Series tunable laser source, like the other new N777xC models, is ideal for cost-effective testing of broadband optical devices because of its ability to step quickly to discrete wavelengths with resolutions up to 0.1 pm and typical wavelength repeatability of ±3 pm. Short wavelength setup times (e.g., 300 ms) enable fast step scanning. Like other laser sources in the N777xC family, it delivers peak output power in excess of +12 dBm and low spontaneous emission levels. With power stability of ±0.01 dB per hour, it can also be used as a static local oscillator with a wide tuning range for receiver testing or transmission experiments.

The structure characteristics and the whole machine structure of the analog oscilloscope

Analog oscilloscope is a kind of analog circuit as the basis of the oscilloscope, display waveform components for the CRT picture tube (oscilloscope), is a more commonly used real-time waveform detection oscilloscope typical analog oscilloscope structure. It is mainly composed of display part, key button control area, test line, probe, shell and other parts.

Equivalent time sampling oscilloscope vs. real-time oscilloscope, what's the difference?

The choice of equivalent time sampling oscilloscope or real-time oscilloscope, in the past, mainly depends on the bandwidth requirements; and now with the introduction of high-performance instruments, this distinction is becoming increasingly blurred. This paper will discuss the principles of sampling input waveforms by each type of oscilloscope and explain their trigger requirements. The advantages of each type of oscilloscope are summarized at the end of the paper.

Structural characteristics of analog oscilloscopes

Analog oscilloscope is a kind of oscilloscope using analog circuit as the basis, display waveform components for CRT picture tube (oscilloscope), is more commonly used a real-time detection of waveform oscilloscope. The whole structure of a typical analog oscilloscope. Mainly by the display part, key knob control area, test line and probe, housing and other parts of the composition.

Types of oscilloscopes characteristics - analog oscilloscopes and digital oscilloscopes (Knowledge II)

Oscilloscope according to the measurement function to be divided into analog oscilloscope and digital oscilloscope two kinds. In practice, the analog oscilloscope can observe periodic signals, such as sine waves, square waves, triangle waves and other waveforms, or some complex periodic signals, such as the video signal of the television set, etc. The structure of the analog oscilloscope sketch, suitable for detecting the more periodic signals.

Types of oscilloscope characteristics-single trace oscilloscope (knowledge)

There are many types of oscilloscopes, which can be classified according to the number of signals displayed by the oscilloscope, the measurement function, the display device of the waveform and the measurement range. Among them, according to the number of displayed signals to be divided into single-trace oscilloscope, double-trace oscilloscope; according to the measurement function of the oscilloscope can be divided into analog oscilloscope and digital oscilloscope.

The function of the oscilloscope applications and types of characteristics

An oscilloscope is an electronic instrument used to display and observe signal waveforms and related parameters, which can observe and directly measure the shape, amplitude and period of signal waveforms, whose shape is shown in the figure. All electrical parameters or physical quantities that can be converted into electrical signals can be converted into equivalent signal waveforms for observation, such as current, electrical power, impedance, temperature, displacement, pressure, magnetic field, etc.

How to use a multimeter, to troubleshoot the circuit board?

The red meter pen is grounded, the red circle of the feet are locations, the negative terminal of the capacitor are locations. The black pen is placed on the IC foot to be measured, then the multimeter will display a dipole value, according to the dipole value to determine the IC good or bad. In the end, the value of how much is good, this is to evaluate the experience, either you have a piece of the motherboard, do a comparison of the measurement on the line.

Senior engineers will also ignore these details (oscilloscope how to make good use of?)

Oscilloscope "trigger" is to make the oscilloscope scan and the observed signal synchronization, so as to display a stable waveform. To meet different observation needs, different "trigger modes" are required. The basic trigger mode of the oscilloscope has three kinds: automatic mode (AUTO), normal mode/regular mode, single mode
