QLS2800 Function Signal Generator / Signal Source / Frequency Indicator / E9P8

Description

The qls2800s series of instruments use large-scale fpga integrated circuits and 32-bit high-speed arm microprocessors.It is an fine test and measurement equipment for electronic engineers, electronic laboratories, production lines and teaching and research.
Features:
Using direct digital synthesis (dds) technology, fpga design, ultra-low consumption;
A 5v adapter , easy to carry.
Using 2.4 inch tft true color LCD screen, with variable function buttons and rotary encoder, greatly enhanced the ease of use of the machine;
Basic function waveforms such as sine , , , sawtooth , and pulse with adjustable duty cycle;
The output signal frequency can be as small as 0.01 Hz;
The waveform frequency resolution is at least 0.01Hz, and the amplitude resolution is at least 10mV
With frequency measurement, counting function;
All parameters can be calibrated by internal procedures.
