FAQ
Q1: What is the RF output frequency range?
A: The specified overall RF output frequency range is 20 MHz to 6 GHz. Appropriate filtering should be selected according to the target operating frequency and required RF performance.
Q2: What is the maximum frequency sweep bandwidth?
A: The maximum specified single-sweep bandwidth is 500 MHz within a selected frequency range.
Q3: Which modulation types are supported?
A: The board supports ASK, FSK, and PSK modulation. Custom waveform requirements can be evaluated separately.
Q4: How is the board controlled?
A: The customer-facing control interface is RS485. Host-computer software and the communication protocol are supplied with the order.
Q5: What is the RF output power?
A: The nominal RF output power is 0 dBm ± 3 dB, with a 20 dB adjustment range in 1 dB steps. This is a low-power RF signal source, not a high-power RF amplifier.
Q6: What power supply is required?
A: The specified power input is 28 V DC, 1 A. Please verify the power connector and supply requirements before integration.
Q7: Can the board sweep across multiple frequency sub-bands?
A: Yes. One signal can sweep back and forth across up to four configured frequency sub-bands. This does not mean four independent RF outputs are available simultaneously.
Q8: Is customization available?
A: Custom waveform and OEM integration requirements can be reviewed. Please provide your required frequency range, sweep pattern, modulation type, timing, and control requirements.
Q9: Is an external RF filter required?
A: Appropriate filtering is recommended according to the operating frequency range and required signal quality. Please confirm the filter configuration for your specific application.
Important Notes
• The overall RF output specification starts at 20 MHz, although the first designed frequency range is listed as 10–1000 MHz. Confirm the usable lower-frequency limit before ordering if operation below 20 MHz is required.
• Frequent switching between the six designed frequency ranges is not recommended because PLL reconfiguration requires a millisecond-level interval.
• The minimum 1 ns dwell time is a specified capability; confirm the applicable operating mode for timing-critical applications.
• The product is intended for low-power RF signal generation, testing, and development.
• Please confirm frequency-specific filtering, control compatibility, and integration requirements before placing an order.
