The VXI unit that came in is an 89640 Vector Signal Analyzer DC-2.7 GHz.. It contains: 89605A RF DC – 2.7GHz input module; E8491B Controller; E1439A 70MHz IF Module; E2730A Down converter for the RF model to work with the 70MHz input unit. Evaluate and troubleshoot your 3G modulation signals with Option B7N 3G modulation analysis. Whether your signal is cdma2000/1xEV-DV or W-CDMA/HSDPA, TD-SCDMA or 1xEV-DO, the tools and analysis flexibility in Option B7N help you test your signal to its standard and troubleshoot the problem if the signal fails to meet its standard. W-CDMA, now with HSDPA Measure, evaluate and troubleshoot your W-CDMA and HSDPA signals with the tools in Option B7N. Use these tools to descramble, despread, and demodulate W-CDMA uplink and downlink signals. The analyzer automatically identifies all active channels regardless of the symbol rate or spread-code-length. Speed measurement set-up with standard pre-sets for uplink (mobile station or user equipment) and downlink (mobile station). Use the composite code-domain power (CDP) and code-domain error (CDE) displays to view all code layers simultaneously and determine the overall performance of your signal and the behavior of specific layers and channels. Also, use the single layer CDP and CDE displays to drill down into your signal to evaluate the behavior of specific layers and channels. Take advantage of the composite and single channel constellation, trellis and eye diagrams, IQ magnitude/phase error displays, and error vector traces to search out specific errors. Use the measurement offset and interval controls to select specific data slots for analysis. For the HSDPA portion of your W-CDMA signal, automatically detect the modulation scheme for HS-PDSCH. Also, despread the HS-PDSCH channels manually or automatically. cdma2000, now with 1xEV-DV The robust and flexible features provided in Option B7N give you the tools you need to test your cdma2000/1xEV-DV signals to their standards and identify the cause if the signal fails to meet its standard. Descramble, despread, and demodulate both the forward and reverse link signals. The software automatically identifies all active channels regardless of symbol rate or Walsh code. Signal analysis capabilities are identical to the advanced tools provided for W-CDMA analysis. These include single layer and composite code-domain power and code domain error traces, composite and single channel constellation, trellis and eye diagrams, EVM, IQ magnitude and phase error traces and much more. 1xEV-DV features include automatic detection of the modulation on the F-PDCH channels, automatic active channel identification and optional predefined F-PDCH active channel configuration for adaptive modulated signals.
