National Instruments' Modulation Toolkit 2.0 and Spectral Measurement Tookit 2.0 are designed for spectrum analysis, analog modulation and digital modulation.
Now consider the case of a signal with analog modulation. This type of signal has a continuous carrier (at the transmit frequency) and carries its information in the modulation of the frequency, amplitude, or phase of that carrier.
Designed for testing and emulation of 2G-, 3G- and 4G-systems, private mobile radio, WLANs and Bluetooth systems, the 3410 Series RF signal generators combine full digital, vector and analog modulation in a 2U rack size.
With excellent phase noise, fast frequency-switching speeds, and a full suite of analog modulation capability, the MG3690C series is an ideal signal source for design and manufacturing test of components and systems for a wide variety of industries--including wireless communications, aerospace and defense, and consumer and computer electronics."
vector signal generator must allow both specify, configure and generate signals of current communication standards, as well as generate a basic analog modulation. at the same time the signal generator must include emulation communication channels and the addition of additive noise (interference) to the channel.
