|Descrizione:||Noise and Interference Emulator|
The TAS 4600A Noise & Interference Emulator provides a convenient, thorough approach for testing RF communications equipment by emulating the co-channel and adjacent channel interference present in wideband communications systems. The TAS 4600A allows thorough testing in a laboratory setting and drastically reduces the time required for product tests. By providing precise carrier to noise (C/N) and carrier to interference (C/I) conditions, the TAS 4600A can be used to test a wide range of wireless voice and data communication equipment, including cellular telephones, cellular modems, personal communication terminals, wireless LANs, pagers, and wireless network equipment, TAS 4600A provides advanced testing features to address a wide range of RF communications technologies. The 4600A delivers these features in a modular format, so your test system can evolve to meet your testing needs for years to come. The TAS 4600A has the following modular features: • Plug-In RF Channel Modules • Plug-In CW Interference Module • Plug-In RF Power Meter • Plug-In System Software PCMCIA Card A single TAS 4600A emulates up to two independent wide bandwidth RF channels, each with independent additive interference, see Figure 1-1. A wide range of C/N, Eb/N0t and C/I characteristics can be programmed for each channel. In addition, the 4600A allows the output power of each RF channel to be directly programmed over a wide dynamic range to allow testing at very low carrier levels. Product Highlights TAS 4600A provides powerful features and a level of integration that are unique for an instrument of this type. These include: • Wideband noise & interference emulation capability exceeds requirements of many wireless communications standards, including IS-97 A/98 A, J-STD- 018/19, and the CDG Interoperability Tests. • Unprecedented two channel capability for the most integrated diversity receiver testing for applications such as CDMA base station evaluation. • Integrated instrument grade RF Power Meter provides accurate RMS power measurements and C/N ratio settings. • Optional built-in dual-tone Synthesizer makes it possible to perform receiver testing under various CW interference conditions. • Wide dynamic range output level control provides the means for testing down to low carrier receive signal levels without the need for external programmable attenuators. • FLASH-memory based calibration constants specific to the instrument enable output power levels and C/N ratios to be set with a high degree of accuracy and repeatability. • TAS 4600A's modular architecture lets your test system capabilities grow as your testing requirements grow. The modular 4600A architecture lets you select the number of RF channels and impairments required to fit both existing and future testing applications. • Standard dual-band RF modules completely address the testing needs of both cellular and PCS applications in a single instrument. • Built-in configurations for industry-standard test procedures. • GPIB and RS-232 control ports make it easy to include TAS 4600A in automatic test systems. • Field-upgradable PCMCIA System Software Card allows quick and easy access to the latest firmware revisions and features.
