Simplify cdma2000 and 1xEV-DO Signal Creation
Keysight Signal Studio software is a flexible suite of signal-creation tools that will reduce the time you spend on signal simulation. For cdma2000 and 1xEV-DO, Signal Studio’s performance-optimized reference signals—validated by Keysight—enhance the characterization and verification of your devices. Through its application-specific user-interface you’ll create standards-based and custom test signals for component, transmitter, and receiver test.
Component and transmitter test
Signal Studio’s basic capabilities use waveform playback mode to create and customize waveform files needed to test components and transmitters. Its user-friendly interface lets you configure signal parameters, calculate the resulting waveforms and download files for playback. The applications for these partially coded, statistically correct signals include:
Receiver test
Signal Studio’s advanced capabilities enable you to create fully channel-coded signals for receiver bit-error-rate (BER), block-error-rate (BLER), packet-error-rate (PER), or frame error rate (FER) analysis. Applications include:
Performance verification and functional test of receivers, during RF/baseband integration and system verification
Coding verification of baseband subsystems, including FPGAs, ASICs, and DSPs
More advanced capabilities operate in real-time mode, which is used to define the parameters of nonrepeating and dynamically changing signals needed for receiver testing. A graphical interface provides a direct instrument connection for parameter transfer and closed-loop or interactive control during signal generation.
Apply your signals in real-world testing
Once you have setup your signals in Signal Studio, you can download them to a variety of Keysight instruments and software platforms. Signal Studio software complements these platforms by providing a cost-effective way to tailor them to your test needs in design, development and production test.
Component and Transmitter Test
The N7601B Signal Studio for cdma2000/1xEV-DO software’s basic capabilities enable you to create waveforms with multiple and mixed carriers for component testing. With the purchase of the N7601B software’s Basic CDMA license, the software generates waveforms in both the IS-95A and the cdma2000 radio formats. With the purchase of the N7601B software’s Basic 1xEV-DO license, the software generates waveforms in both the 1xEV-DO Rev. 0 and 1xEV-DO Rev. A radio formats. Both Basic licenses allow the software to generate waveforms in all four radio formats.
Designers and manufacturers of both access network (AN) and access terminal (AT) components will find the N7601B Signal Studio for cdma2000/1xEV-DO extremely useful. The N7601B software provides cdma2000, IS-95A, and 1xEV-DO waveforms for testing many cdma products, such as multicarrier power amplifiers (MCPAs) and dual-mode handset components.
Using the N7601B software’s CCDF capability, you can verify the performance of your handset (MS or AT) power amplifiers for all of the radio formats.
Signal Studio for cdma2000/1xEV-DO allows you to test MCPAs with up to 25 carriers placed within a 160 MHz bandwidth. The forward link waveform includes an idle slot gain feature that can be used to vary the noise level relative to the pilot channel during idle slot transmissions. This allows the on/off power ratio to be set to meet the transmission envelope mask requirements of the system. Forward and reverse link physical channel parameters can be individually configured in each timeslot.
The waveforms provided by the N7601B Signal Studio for cdma2000/1xEV-DO software enable you to perform the following component tests:
