precisionWave Corp. has introduced its next RF Vector signal generator. The p1511A generates digitally modulated and CW signals in the 800MHz to 1000MHz and 1700MHz to 2200MHz cellular bands for developers and testers of cellular technology based products. The instrument's I/Q generator produces high-accuracy signals for any digital modulation scheme used in these bands. As examples, EDGE avg. RMS EVM is typically less than 0.8 per cent and GSM phase error is below 1°. With a wide -100dBm to 20dBm power output range, harmonic suppression is better than -40dBc at 13dBm, and spurious is below -8dBc. The source's 1GHz CW phase noise is less than -100dBc/Hz at 20kHz offset, and at 2.2GHz is better than -92dBc/Hz at20kHz offset.

The p1511A is suitable for high accuracy, low Error Vector Magnitude (EVM) signal generation. EVM is the industry standard for modulation quality measurements of digitally modulated signals. EVM measurements can reveal a variety of digital signal problems and can illuminate the causes of these issues. Signal sources must have low EVM output so designers and testers can properly evaluate the performance of chips, modules and devices for digital communication reception and transmission.

The p1511A measures 3U(h) x 19"(w) and 17"(d), and is suited for ATE applications, having frequency and power switching times of 15 ms and 2.5 ms respectively. Included instrument libraries and APIs for Microsoft Visual Studio enable rapid development of LAN-based instrument control software.

precisionWave's web-based waveform download capability customises the p1511A with the needed standard and custom waveforms. Users may also develop their own custom I and Q waveforms.

Like all precisionWave instruments, the source is CE certified and is fully warranted for one year.
