Vector signal generator
What is a vector signal generator?
Vector signal generator is a device that is able to synthesize arbitrary passband signals. It can be used for test, measurement and debug purposes.

We present a multi-functional vector signal generator that supports arbitrary vector signal generation and can be used for UMTS, CDMA-2000, WiMAX, 3GPP LTE, OFDM systems, among others.
It is a few times cheaper than most other vector signal generators. To reduce costs, it doesn't have a front panel with buttons, and is controlled from the external PC instead.

How does vector signal generator work?
Every passband signal can be represented in the following form:
where I(t) and Q(t) are the components of the complex envelope. I(t) and Q(t) are baseband signals, therefore they can be generated very simply.
The I(t) and Q(t) signals are then used to modulate the carrier frequency ω.

What types of signals can a vector signal generator synthesize?
Vector signal generator can synthesize virtually any type of passband signal that has a carrier frequency from a few hundred MHz to a few GHz, and a spectrum width of about a hundred MHz. Ultra-wideband (UWB) signals can't be synthesized by a vector signal generator.
It is possible to generate signals with the following modulation types with a vector signal generator:
- Amplitude shift-keying (ASK), frequency shift-keying (FSK), phase shift-keying (PSK)
- quadrature amplitude modulation (QAM), trellis-coded modulation (TCM)
- continuous phase modulation (CPM), including CPFSK, MSK and GMSK
Vector signal generator applications
Vector signal generator can be used:
- to debug receiver modules,
- to measure various receiver parameters,
- to explore noise resistance of a communication system.
