SGP2100S series
Fully programmable dual-channel function generator
Product Introduction
SGP2100S series DDS signal generator is feeltech launched in 2015, a cost-effective, versatile signal generator product, instrument uses large scale integrated circuits and high-speed FPGA MCU microprocessor, the internal circuit active crystal made reference signal high stability. Surface mount technology, greatly improving the instrument noise immunity and service life. Display interface using LCD1602 LCD display is divided into two lines, the top line shows the current frequency, the following line display other parameters or features variable. The instrument signal generator, waveform scanning, measuring and using parameters have great advantages, is an electronics engineer, electronics laboratories, production lines and teaching, research ideal test, measurement equipment。
SGP2100S instrument model of the last two digits 00 indicate limits (MHz) frequency sine wave on the instrument model. Example: SGP2102S, 02 means the model sine wave output frequency up to 2MHz。
The three most important source indicators: frequency, amplitude and offset level, so we in the procurement of the signal generator must consider several important parameter index, so that we can get a product that best suits your。1.About frequency：When you purchase, as long as the instrument maximum output frequency is greater than the highest frequency that you want to use on the line, need to be reminded that the said instrument on the market generally refers to the maximum output frequency of the sine wave is the maximum output frequency. If you need is a square wave, you need to confirm your purchase equipment square wave output frequency is the highest number。2.About amplitude：When you purchase equipment, to be considered the most significant instrument output signal range is how much, if you are buying the instrument amplitude range is too small, then the future will use the occasion of this instrument is greatly limited。3.About bias level：A formal standard signal generator, the bias level can be adjusted in all. In the experimental circuit, the signal that with any DC bias is extremely common. If the signal generator output bias can not be greater than 5V, the signal less than 1V peak to peak, so that the product can be said that basically there is no practical value。I will now highlight the characteristics of the instrument are described below：
1. The high signal stability
The instrument maximum stable output waveform signal 20VPP while the machine comes 20DB and 40DB attenuation circuit can stabilize the output of small-signal 10mVpp. So that the instrument wide range of applications。
2.Waveform species diversity
Can output sine, square, triangle, pulse wave, staircase, ascending sawtooth, descending sawtooth。
3.Versatile Measurement
Shortcut keys, having a key to enter the function interface, the instrument can measure not only the frequency, but also has a 10-bit decimal counter。
4.Bias level adjustment precision
This instrument bias level can -10V to + precise continuously adjustable between 10V, this function in experimental field sensor signal simulator, teaching experiments are necessary conditions, so be sure to consider before buying the instrument bias whether the level can be arbitrarily set the size。
5.Sweep more flexible
Shortcut keys, having a key to enter the sweep function interface, the machine can achieve linear and logarithmic sweep sweep，The maximum time of up to 999 seconds sweep, sweep start frequency and stop frequency can be set。
6.Easy installation
Panel embedding mounting structure, user-friendly product integration。
7.Wide voltage supply range
Native support DC14V-DC35V wide voltage supply range
