Product Description
2.4" QLS2805S-5M DDS Signal Generator/Counter Frequency Counter
Description:
The QLS2800S series instruments use large-scale FPGA integrated circuits and 32-bit high-speed ARM microprocessors. The internal circuit adopts SMT, which greatly improves the anti-interference and service life of the instrument. 2.4-inch TFT LCD screen features high resolution of 320*240. It can display all the parameters of the channel and prompt the current button functions, making good use of the button resources and greatly enhancing the operability.
The instrument has great advantages in signal generation, waveform scanning, parameter measurement. It is an ideal test and measurement equipment for electronic engineers, electronic laboratories, production lines and teaching and research.
Features:
- DDS technology, FPGA design, ultra-low power consumption
- Easy to carry and use with a DC5V power adapter
- 2.4-Inch TFT Colorful Screen: Easy to use with variable function buttons and rotary encoder
- Basic function waveforms including sine wave, triangle wave, square wave, sawtooth wave, and pulse wave with adjustable duty cycle
- Minimum frequency of output signal stands at 0.01Hz
- 10 Groups of parameter storage bits from M0 to M9. Automatically recall the data of M0 when it is powered on
- Waveform frequency resolution is 0.01Hz, and its amplitude resolution is 10mV
- 2 Trigger Modes: Manual and external triggering modes. It can output any pulse train from 1 to 999999.
- The duty cycle adjustment of pulse wave is accurate to 0.5%
- Frequency scanning with an end point
- With frequency measurement and counting functions
- All parameters can be calibrated by internal procedures
- Powerful communications function: completely open communication protocols makes secondary development easier
- After connecting to your PC, the PC can be used to control the instrument
