VG4-01M-C42HP3U375A - Vector Signal Generator Print E-mail

Vector Signal Generator up to 4 GHz

VG4-01M-C42HP3U375A - Vector Signal Generator VG4-01M-C42HP3U375A - Vector Signal Generator
RF vector generator is used for generation of the signal in form Re[(I(t)+jQ(t))ejωt], fwhere I(t) and Q(t) – sampled interval of quadrature signals (i.e. complex signal), written in device memory, ω – carrier frequency. On the front panel all intermediate signals are available for user – i.e. I and Q channels, local oscillator (LO) and output signal RF. Vector signal generator is controlled via USB port of a personal computer.

Features
  • RF output frequency range: 0.1 – 4 GHz (in vector mode), 62.5 – 8 GHz (in scalar mode);
  • RF output level tuning range: -10..+10 dBm (in vector mode), -30..+0 dBm (in scalar mode);
  • Modulation types: QAM, PM, FM and all its modifications;
  • Baseband: 66 MHz;
  • Hardware interpolation: up to 4096;
  • Hardware NCO with 32-bit phase and frequency control;
  • Hardware phase and frequency digital modulation;
  • Control interface: USB 2.0.

Description

Vector signal generator VG4 has modular architecture based on the FXP bus and consists of the following functional plug-in units (Pi-Us):

  • I/Q Baseband Generator – DVM Pi-U;
  • Analog Quadrature (Vector) Modulator – AVM Pi-U;
  • RF Frequency Synthesizer – LNO Pi-U, forming LO signal for the AVM block.

Interconnection diagram is shown in the fig. 1. Each of the plug-in units shown can also be used independently. For this reason all necessary connectors are available on the front panel.

Applications

Vector Signal Generator allows to solve the following problems:

  • debugging of receiver blocks of communication systems;
  • analysis and debugging of hardware demodulation algorithms;
  • analysis of the noise immunity and stability of the digital communication systems.

As for the first task – one can debug frequency conversion path both in the transmitting block (directly connecting I and Q outputs from DVM to the design under test) and the general operation of the receiving part, generating the signal with required modulation at the AVM RF output.

As for the second task – vector generator besides forming the required signal can also simulate the following effects:

  • additive noise with arbitrary spectral density and probability characteristics;
  • carrier phase noise with specified spectral density;
  • deviation and phase offset of carrier and symbol frequency;
  • quadrature phase error;
  • mutual I and Q time offset.

As for the third task – VG4 allows to form a noise interference signal with specified characteristics for the stability analysis of the digital communication systems.
