The cdma2000/cdmaOne measurement application is one in a common library measurement applications for the Keysight modular PXI VSAs, providing standard-based transmitter tests by adding fast one-button RF conformance measurements to help you design, evaluate, and manufacture your CDMA transmitters. The measurement application is fully standard compliant to the 3GPP2 Release A helping you check your CDMA design with confidence and support manufacturing with a single application covering IS95/cdmaOne, cdma2000 technologies for production testing.
RF transmitter testing
- Full power and spectrum suite measurements with Pass/Fail indicator: channel power, adjacent channel power, spectrum emission mask (SEM), spurious emissions, occupied bandwidth(OBW) and complementary cumulative distribution function (CCDF)
- Quickly identify different data rates on specified channels with Marker selection. Easily de-spread the code channel signal into its symbol level with symbol power and symbol EVM measurement results, even in the presence of multiple code channels.
- Easy to verify overall modulation accuracy of a transmitter with all spreading and scrambling problems by using composite rho measurement
Signal analysis
- Complies with 3GPP2 Release A, supports IS-95 or cdmaOne and cdma2000® for forward link and reverse link
- Forward link and reverse link RF transmitter measurements
- One-button measurements with pass/fail per the standard
Measurements
- Forward and reverse link: Composite rho and EVM, QPSK EVM, code domain, code domain error, frequency error, time offset and power measurements, etc
- Automatic detection of forward link signals from radio configuration (RC) 1 to 5
- Display code domain power (CDP) results in Hadamard or bit-reverse
- Specify chip and PN offsets, and measurement interval from 1 to 32 PCG (1 PCG=1536 chips)
Performance (hardware dependent)
- Composite EVM Accuracy: 0.5%
- Analysis bandwidth: Up to 160 MHz (with M9391A Option B16)
- Compatible with M9391A PXI VSA
Other features
- License key upgradeable
- Transportable software license supports up to four PXI VSAs in one mainframe
- SCPI remote user interface
