Description QLS2805S-5M DDS Signal Generator Function Generator Frequency Counter with Color LCD Communication Description: It uses a large-scale FPGA integrated circuit and a 32-bit high-speed microprocessor (for ARM). Its internal circuit adopts surface mount technology, which greatly improves the anti-interference and service life of the instrument. The display interface adopts a 2.4-inch TFT LCD screen with a high resolution of 320*240, which can display all the parameters of the channel and prompt the current button function. It effectively utilizes the button resources, avoids the user’s frequent button operation, and greatly enhances its operability. Features: – Using direct digital synthesis (DDS) technology and FPGA design, featuring ultra-low power consumption – Powered by a single DC5V power adapter; easy to carry and use – 2.4″ TFT true color LCD screen and variable function keys and rotary encoder enable easy operation – Basic function waveforms such as sine wave, triangle wave, square wave, sawtooth wave, and pulse wave with adjustable duty cycle – The minimum frequency of output signal can reach 0.01HZ – There are 10 groups of parameter storage bits from M0 to M9, and the data of M0 will be automatically recalled when the machine is turned on – The minimum waveform frequency resolution can reach 0.01HZ, and the minimum amplitude resolution can reach 10MV – With manual trigger and external trigger modes, the machine can output any pulse train from 1 to 999999 – Pulse wave duty cycle adjustment is accurate to 0.5% – Frequency sweep with endpoint – With frequency measurement and counting function – All parameters can be calibrated by internal program – Powerful communication functions and open communication protocols make easy to do secondary development – After connecting with a PC, users can use the PC to control the instrument – Switch between Chinese and English interface Technical Parameters: Main Features: – Frequency range: sine wave (QLS2805S) 0HZ~5MHZ; square wave 0HZ~2MHZ; triangle wave 0HZ~2MHZ; sawtooth wave 0HZ~2MHZ – Output modulation: frequency sweep and trigger – Waveform types: sine, square, triangle, and sawtooth – Frequency error: ±8×10-6 – Frequency stability: ±5×10-6 – Amplitude range (peak-to-peak): 10MVP-P to 10VP-P – Output impedance: 50Ω±10% – Amplitude Resolution: 10MVP-P – Amplitude stability: ±0.5% (every 5 hours) – Amplitude error: ±1%+10MV (frequency 1KHZ, 8VP-P) – Bias Range: -100% to +100% Sine Wave: – Harmonic rejection: 40DBC (<1MHZ); 35DBC (1MHZ~5MHZ) - Distortion: <0.8% (20HZ~20KHZ) Square Wave: - Rising edge time: ≤28NS - Overshoot: ≤10% - Duty cycle adjustment range: 0.1%~99.9% TTL/CMOS: - Rising edge time: ≤28NS - Low level: <0.3V - High level: 1V~5V Sawtooth Wave: - Duty cycle >50.1%: Rising sawtooth – Duty cycle <49.9%: falling sawtooth Scanning: - Sweep Mode: Sweep - Scan time: 0.1S~999.9S - Scan range: 0-MAX.FREQ External Measurement Function: - Frequency measurement range: 0.01HZ~60MHZ - Minimum input voltage: 0.5VP-P - Maximum allowable input voltage: 10VP-P - Counting range: 0~4294967295 - Counting method: Manual - Source selection: EXT.IN input (analog signal) Storage: - Quantity: 10 - Location: M0 to M9 Interface: - Interface: USB to serial interface - Communication rate: 57600BPS - Communication protocol: The command line method is adopted, and the protocol is public Others: - Power supply: DC: 5V - Product size: 200 x 170 x 70mm/7.9 x 6.7 x 2.8" - Net weight (machine only): 518G/1.1LB Functions: 1.
