Pulse Power & Measurement Ltd.,Swindon UK has launched the S1000 multi-channel signal generator from IZT Labs GmBH.
The S1000 signal spectrum generation is the ideal tool for testing and developing modern radio systems. These systems have multiple receivers and multiple sources of noise and interference. These signals can be from more than one antenna, with independent carriers and different modulation formats. To test this, engineers require a signal generator that can generate multiple signals in a controlled and coherent manner. The IZT S1000 can combine its 31 'virtual' signal generators to match receiver test requirements, without the need for a costly batch of standard, single channel, RF generators. This way, test engineers can simultaneously create multiple signals to test complex radio systems, whether it is at the semiconductor level or at the system level. For each virtual signal generator, the engineer can define signal-content, real-time modulation I/Q data streams, and many other parameters. Real-world simulation is enhanced with support for multiple forms of signal impairment.
The IZT S1000 provides accurate frequency and time synchronisation allowing for absolute launch timings and phase-locked frequencies. Receivers with multiple antennas can be fed with a combination of signals from multiple RF outputs with controlled delay, frequency and phase relationship, and with identical or different content. This makes the IZT S1000 the ultimate signal source for over-the-air and MIMO testing.
"With its virtualised architecture and IZT's patented signal processing algorithms, the IZT S1000 combines into one instrument, all the tools needed to generate test scenarios for today's demanding testing requirements," explains Rainer Perthold, CEO of IZT. "Modern radio systems must be tested for the correct operation of all broadcast radio standards under real-world conditions. This can include conventional AM and FM radio, DVB-T, DAB, HD Radio, and satellite radio such as Sirius/XM. In addition, most vehicles have GPS receivers and Remote Keyless Entry (RKE) wireless systems."
The system has four gigabytes of fast RAM (expandable to eight) for waveform data with up to 320 Samples/second total bandwidth. It can be loaded from the internal hard drive or from a server via two GBit Ethernet ports. Each port can handle up to 24 MS/sec at 16-bit resolution.
The IZT S1000 comes in a compact 2U form factor chassis with high-resolution display and front panel keyboard. The chassis contains all digital processing hardware, synthesizers and RF sections. The front panel and graphical user interface have been designed for rapid user-friendly control of multiple signals. The IZT S1000 can be controlled remotely with SCPI commands received via RS-232, LAN or GPIB.
