Introduction of Suin SS7406 Frequency Counter/Timer/Analyzer

Frequency counters are test instruments used in many applications including laboratories, education, and industrial field to measure the frequency and time of signals very accurately. Nowadays high speed and more accurate frequency counters are required by engineers, Suin SS7406 Universal Frequency Counter/Timer/Analyzer comes out in this condition.

Main Features:

SS7406 can measure frequency, period, time interval, pulse width, duty cycle, phase difference. Frequency can be tested from 1mHz to 200MHz in two channels. Additionally, several higher frequency options max to 40GHz can be selected in channel 3. 11 digits per second frequency resolution makes it suitable for measurement from short-term phase locked loop jitter to the long-term drift of atomic clocks. 25ps single shot time resolution makes it one of the highest resolution counters in the market.

 

Besides that, SS7406 also can measure frequency ratio, limit, and statistics calculation. This complete measuring function makes it more popular in the market.

 

The standard time base’s nominal frequency is 10MHz. The test can be controlled not only by the internal gate automatically, but also by the external signal triggering. For more stable measurement, there is a high stability crystal oscillator as an optional selection.

 

Advantages:

Unlike conventional counters that only have numeric displays, SS7406 provides live, graphical displays of measurement results. Graphical data is available in two formats: histogram and trendgram. You can select any by your real requirement.

Meantime, it is designed as 2U instrument case, which can be used not only as a sole benchtop instrument but also in a 19'' equipment cabinet.

New Arrival - Update Version Digital AC Millivolt Meter SM2100 Series

Voltage, current and frequency are the basic three measured parameters in the electrical measurement, of which voltage measurement is very common. As the technology of electronics develops, low voltage measurement becomes more important. Therefore, the millivoltmeter becomes an essential tool. In addition, digital instruments catch users’ fancy because of accurate and convenient reading, higher accuracy, tiny error, higher sensitivity and resolution, and fast measurement speed, so the demand for digital AC millivoltmeter is growing.

The traditional analog voltmeter adopts an average detecting solution, which has a bigger error on the test result, while the current digital multimeter can measure the signal at the millivolt level but is limited by a narrow measurement range.

Considering to above reasons, Suin Instruments adopts an integral amplifier detecting solution to update the new version digital AC millivolt meter SM2100 series, which overcome the defect of the traditional analog voltmeter. Meantime, the instrument applies a 16-bit high-performance CPU and A/D converter and can measure AC voltage 50μVrms to 400Vrms of Sine signal frequencies between 5Hz to 6MHz, which improves the measurement range greatly.

 

Figure 1 – SM2100 Series Working Principle

Dual independent channels are configured on the SM2100 series, thus the measurement for two different signals could be performed at the same time. LED screen with the colorful digits display, clear readings, and better vision, which could display the test result as 3 1/2 digits or 4 1/2 digits simultaneously, and the best solution could reach 0.1μV. Most importantly, the result could also be shown as different units-Vrms, Vpp, dBV, dBm, dB, and W. Ground and Floating setting and maximum undamaged input voltage up to 400Vrms can improve the operation safety greatly.

High accuracy, high stability, easy operation, and high safety make the SM2100 series digital AC Millivolt Meter widely used in universities, factories, military units, labs, and scientific institutions, it becomes a necessary basic instrument to measure and test voltage.
