The function of the real time  spectrum analyzer  is to display the signal amplitude of the frequency domain in the same moment. Its working principle is there are correspondent filter and detector for different signal frequency, then transfer the signal to the CRT screen. The advantage of the real-time  spectrum analyzer  is the immediate reaction of the periodic random waves, and the disadvantages of it are the high price cost and the limited range of the frequency width.

The sweep-tuned  spectrum analyzer  is frequently-used. Its basic structure is similar with the superheterodyne receiver. The working principle of the sweep-tuned  spectrum analyzer  is adding the signal to the mixed wave device through the attenuator, then the under clocking IF signal through reamplifying, smoothing, detection are sent to the vertical direction board of the CRT.

The  signal generator  is a device which can provide all kinds of frequency, wave form. During the testing the amplitude characteristic, frequency characteristic, transfer characteristic and other electrical parameter of the telecommunication system or the equipment, the signal generator can be used as the signal source. The  signal generator  can be called signal source or the oscillator, which has a wide application in the production practice and technology territory. All kind of squiggle can be showed with the equation. The  signal generator  also has a wide application in the experiment of circuit and detection. For example, in the communication, broadcast, TV system. In the territory like industrial, agricultural, bio-medicine, such as high frequency induction heating, melting, quenching, ultrasonic diagnosis and others.

SS2900 series cell-type radio frequency switch is supplied by our company, in addition to this, there are many information for the  spectrum analyzer . Direct current main is the device to form the steady current in the holding circuit. Such as dry battery, storage battery, direct-current generator,etc. The direct current main has two electrode, the anodal has a higher potential and the cathodal has a lower one. When we connect the two electrodes and the circuit, it can keep constant PD between two end of the circuit, in order to form the electric current from the anodal to the cathodal. So, the direct current main is a energy transfer device, it can supply the energy to the circuit form other energy form, which can maintain the stable flow of the current. There are the main applications: 1. Electrolytic condenser; 2. Test the resistor, relay, motor or other electronic components; 3. Automatic test equipment or electronic equipment in the lab; 4. Other occasion where...

Programmable DC power supplies  is also called DC stabilized power supply. Its service voltage is mostly alternating voltage, when the alternating current or output load resistance change, the direct output voltage of the voltage stabilizer can still keep stable. It can be divide into two parts form the working style: 1. Controlled rectification style. It can adjust the output voltage though changing breakover time of the thyristor. 2. Chopped mode. Import the unstable direct voltage, in order to change the break-make ratio of the on-off circuit, then get the stable direct voltage after smoothing. At present, the development of the programmable  DC power supplies  tend to be small size, high efficient, and digitization. More and more equipment adopt the singlechip to control the switch, greatly improve the efficient and stability.

The Suin is the professional supplier of the  spectrum analyzer ,  signal generator,  power analyzer and DC converter. If you are interested with our products, please feel free to contact us. Now, let’s have brief introduction of the DC converter. The DC converter is an equipment that can change one voltage direct current into another or several voltage. And the DC converter has two kinds: parallel and unparalleled. 1. Parallel DC converter adopt the advanced high frequency PWM resonance technique, which can improve the efficiency. It has the features like high voltage stabilization, antijamming capability, low output noise, quick dynamic response, wide working temperature and others. 2. The unparalleled DC converter consist of the DC-DC modules. It has the features such as high voltage stabilization, antijamming capability, low output noise, and small size and light weight.

Programmable DC power supply  can protects itself by warning and cutting off output once the controlling module gets faults, transistor over-heating, and internal bus gets faults. SK13530 programmable power supply is a new generation of  programmable DC power supplies .It is widely applied in national defense, institution, university and factory, especially in the areas of computer measuring and automatic control system as DC power supply.

The  signal generator  has the function of signal modulation. What is the signal modulation? The signal modulation refers to the in the modulating signal, frequency change inset the LF signal into the HF carrier signal. The the signal can transfer any information from data to video. The signal modulation can divide into analog modulation and digital modulation. The analog modulation like AM and FM are often applied in the broadcast communication; while the digital modulation is on account of two states, and allow the binary data.

The  signal generator  is also called signal source or oscillator, which is widely used in the production practice and science and technology field. Various waveform curve can be represented by trigonometric function equation. It can also generate many waveform, such as triangular wave, sawtooth wave, rectangular wave, sine wave, etc.  Signal generator  has a widely usage in the experiment of circuit and equipment detection. For example, in the system of communication, broadcast and television, if you want to carry the video signal or pulse signal out, you need the signal generator which can generate the high frequency. In the field of industry, agricultural and biomedicine, such as the high-frequency induction heating, smelting, hardening, ultrasonic diagnosis, MPI, etc, the high or low frequency signal generator are all needed.

Spectrum analyzer  is used to study signal distortion, modulation, spectral purity, frequency measurement stability and inter modulation distortion signal parameters. It also can be used to measure some parameters of amplifier and filter circuitry, which is a versatile electronic measuring instruments. It is also called frequency domain oscilloscope, analyze oscilloscope, harmonic analyzer, etc. Modern  spectrum analyzers  can display the results of the analysis in analog or digital mode. If the interior of the instrument uses digital circuits and microprocessors, it will have storage and computing functions; it is easy to constitute a test system with the configuration standard interface.

Power supply , also known as voltage regulator. With the development of electronic technology, especially after the application of computer technology to various industrial, scientific fields. Various electronic devices require a stable power supply, power supply can not meet the needs. So power supply appears to solve this a problem. Commonly used AC  power supply  have: 1.Ferroresonance exchange AC regulator which consist of the saturable reactors and the corresponding capacitors, having constant voltage characteristics. 2.AC magnetic amplifier regulator which is to cascade the magnetic amplifier and auto transformer, then electronic circuit changes the impedance of the magnetic amplifier to stabilize the output voltage. 3.Sliding exchange AC regulator. By changing the position of the contact slide transformer output voltage stability. 4.AC induction regulator.
