Description
The APVSGXX-X is a multi-channel version of an ultra-fast-switching vector signal generator, covering a continuous frequency range from 10 MHz to 4, 6, 12, 20 or 40 GHz. The APVSGXX-X enables outstanding ultra-fast phase-synchronous frequency sweeps, chirping, intra-pulse modulations, pulse shaping, all with very low phase noise. For each output, a high performance internal I/Q modulator enables independant customized modulation waveforms and supports dedicated modulation schemes. The device can be easily controlled remotely accessed via Ethernet and USB using standard SCPI command language. A PC based graphical user interface (GUI) is supplied to control the device and provide a easy-to-use interface for uploading pre-calculated IQ data files. The GUI supports various file formats including a propriatary IQ data file format.
The APVSG-X with 2, 3 or 4 channels is mounted in a 19‘‘ 2HU enclosure (86 H x 426 W x 480 mm L [3.4 H x 16.8 W x 18.9 in L], 18 kg).
The key features are:
- High RF signal bandwidth: using a dual, arbitrary waveform generator operating at 500 MHz sampling rate for I/Q signal generation. The generator has built-in support for the common vector modulation schemes and it provides direct support for the controlled injection of additive white Gaussian noise (AWGN) into the signal path.
- Outstanding signal purity of modulated signals: lowest phase noise (-145 dBc/Hz at 1 GHz and 20 kHz offset), low spurious and excellent harmonic rejection
- Excellent EVM and ACPR performance
- Full set of built-in analog modulations like AM, FM, PM, Pulse
- Ultra-narrow pulse trains (< 5 ns), linear and non-linear pulsed frequency chirps
- Built-in digital modulation schemes like FSK, PSK, ASK, QAM
- Ultra-fast frequency hopping and sweeping capability (update frequency, power and phase in below 200 ns)
- Powerful trigger system including multiple markers and input triggers.
- Fast control port (FCP) (parallel BCD interface) for fast external signal control
- Security: external microSD available
The applications include:
- Compact ultra-high performance vector signal generator IQ data streaming
- Coherent independantly programmable multi-output configurations for phase array and antenna beamforming
- Simulation of complex signal environments for radar, electronic warfare (EW) and antenna tests
- Quantum computing: QuBit manipulation and Control, low-latency sequential playback, fast adaptive pulse shaping, etc.
- The APVSG is designed for high reliability and fast, easy calibration, service, and repair. The modular system assembly simplifies repair and guarantees low maintainance costs.
