Product Overview:
The Sihui AV1442 RF Signal Generator is a product designed for RF applications in communication and electronics. It comes in two models: 1442 and 1442A, covering frequency bands of 250kHz to 6GHz and 250kHz to 3GHz respectively. It adopts a modular structure design, featuring low phase noise of the output signal, high frequency resolution and accuracy, and a wide output dynamic range. It can provide high-performance complex analog simulation signals for communication and radar equipment testing, covering all commonly used RF frequency bands. It has a fully Chinese interface and large-screen menu control. The output signal phase noise is extremely low, the frequency resolution and accuracy are high, the output dynamic range is large, and it has rich analog modulation, digital modulation and programmable functions. This product can provide high-performance complex analog simulation signals for communication and radar equipment testing, and is applied in product research and development, production, testing and maintenance, etc.
Product Features:
User-friendly interface: It adopts a large-screen Chinese operation interface, and can also be set to an English interface. The current status information is clearly presented, facilitating user operation.
Low phase noise: It has excellent near-carrying-phase noise. For example, at a 1GHz frequency and a 1kHz offset, the measured value can reach -124dBc/Hz. The spectral purity is high, meeting the testing requirements for pure RF excitation signals in radar system development and satellite communication.
Wide power output range: The power output range is -135dBm to +7dBm. If the 115dB programmable step attenuator option is configured, the output power dynamic range can be further expanded.
Rich modulation functions: It supports amplitude modulation, frequency/phase modulation and other analog modulation. The internal function generator can provide various waveforms such as sine waves, square waves and triangular waves. It also supports digital modulation such as BPSK, QPSK, OQPSK, etc., with a symbol rate of 10ksps to 10Msps (for MSK and 2FSK modulation formats, the maximum is 2Msps).
Scanning function: It has step and list scanning functions to meet different testing needs.
Easy upgrade and maintenance: It provides a USB interface, allowing for intelligent software upgrade and data backup using a USB drive, facilitating user maintenance of the instrument.
Rich interfaces: It is equipped with RS232 interface, GPIB interface, LAN interface, etc., facilitating system setup. It can also realize remote control and network upgrade functions through the LAN interface. At the same time, it provides baseband output interface, supporting external I/Q signal input and internal baseband generator's I/Q signal output, etc.
