Test cdma2000 and IS-95A Components and Receivers
Option 401 enables the creation of standards-based IS-95A and cdma2000 test signals. This option provides a comprehensive suite of test signals for existing 2G and evolving 3G CDMA base station and mobile transceivers and their components.
Create Up to 12 SR1 or SR3 Carriers to Test MCPAs
Generate single and multi-carrier forward and reverse link test signals to stress components. Each carrier can have up to 256 configurable channels to simulate multiple base stations or mobiles transmitting on the same carrier frequency. Quickly setup common channel configurations by selecting from five preset configurations or customize each of your carriers channel configuration. Reduce stress on power amplifiers by clipping the peak-to-average power before or after baseband FIR filtering. These statistically correct IS-95A and cdma2000 signals are ideal for testing your cellular components under real-world conditions.
Fully Coded Signals for Receiver BER/FER Analysis
Test receivers with fully coded single-carrier forward and reverse link cdma2000 signals. These coded channels are great for BER/FER receiver testing and baseband ASIC/DSP verification. Modify signal coding parameters in real-time to efficiently test demodulation and decoding algorithms without waiting for long arbitrary waveform rebuild and download delays. Both forward and reverse link channels are fully coded with long and short codes, cyclic redundancy checks, convolutional or turbo encoding, interleaving, power control, and complex scrambling. For receiver tests in the presence of AWGN, the optional calibrated noise personality enables setting the signal to noise ratio as Eb/No or C/N with digital accuracy.
Test power amplifiers, MCPAs, filters, modulators, demodulators, and other components with real-world IS-95A and cdma2000 test signals. Common measurements include adjacent channel power ratio, blocking, and modulation accuracy.
Test mobile and base station receivers with fully coded test signals that enable PER and BER analysis. Common measurements include receiver sensitivity, maximum input level, and demodulation performance in the presence of interference.
This option can be added as a product upgrade.
