APVSGXX-X Series Multi-Channel Costophor Vector Signal Generator-Output Up to 40GHz

Classification:

Signal generator

The APVSGXX-X series is a multi-channel version of the high-speed switching APVSG series vector signal generator, covering a continuous frequency range from 100 kHz to 4, 6, 12, 20 or 40 GHz. APVSGXX-X frequency sweep, chirp, intra-pulse modulation, pulse shaping and other waveforms that achieve excellent ultra-fast phase synchronization and coherent output, all with extremely low phase noise. For each output channel, the high-performance internal I/Q modulator enables individual custom modulation waveforms and supports user-defined modulation schemes. The device can be easily accessed remotely via Ethernet and USB using the standard SCPI command language. Provide a PC-based graphical user interface (GUI) to remotely control the device and provide an easy-to-use interface for uploading pre-calculated IQ data files. The GUI supports a variety of file formats, including the proprietary IQ data file format. The APVSGXX-X series multi-channel coherent vector signal generator has 2 or 4 individually controllable and coherent channels in a 19-inch 2HU housing. The overall machine size is very compact (86 high x 426 wide x 480mm long [3.4 high x 16.8 wide x 18.9 inches],18kg).

  • Multi-channel phase parameter vector signal generator main features:

    ● Output of up to 4 individually controllable and correlated channels in a 2HU chassis

    ● Up to 400MHz RF signal modulation bandwidth: Use dual arbitrary waveform generators operating at a 500 MHz sampling rate to generate I/Q signals. The generator has built-in support for common vector modulation schemes and provides direct support for controlled injection of Additive White Gaussian Noise (AWGN) into the signal path

    ● Excellent signal purity of the modulated signal: phase noise (-145dBc/Hz @ 1GHz,20kHz offset), low spurs and low harmonics

    ● Excellent EVM and ACPR performance

    ● Support 4096QAM high-order modulation

    ● Complete built-in analog modulation, such as AM, FM, PM, pulse

    ● Ultra-narrow pulse trains (< 5 ns), linear and nonlinear pulse frequency chirps

    ● Built-in digital modulation schemes such as FSK, PSK, ASK, QAM

    ● AWGN additive white Gaussian noise output

    ● Ultra-fast frequency hopping and frequency sweeping capability (update frequency, power and phase speed below 200ns)

    ● Powerful trigger system including multiple markers and input triggers

    ● High-speed download port (FCP) for high-speed external signal data flow (parallel BCD interface)

    ● Security: External microSD available

    ● Flexibility: The APVSG GUI supports data formats from different vendors. The internal RAM can store 512MS (32 bits per I/Q sample) of IQ data. APVSG internal AWG can play selected parts of RAM when triggered by user

     

    The main applications of multi-channel phase parameter vector signal generator include:

    ● Compact ultra-high performance vector signal generator and IQ data stream playback

    ● Phase coherent per channel individually programmable multiple output configuration for phased array and antenna beamforming

    ● Directly used for the generation of multiple quantum Qbit pulse pattern signals

    ● Complex signal environments for radar, electronic warfare (EW) and antenna testing

    ● Multi-channel Coincident Microwave Receiver Component Testing
