TAS 4600 In Stock

The TAS 4600 by Spirent is an advanced Noise and Interference Emulator designed for integration into various test setups involving the IS-98A phone. In this specific configuration, this noise and interference emulator is a crucial component alongside a base station emulator, RF channel emulator, C/N emulator, and a mobile phone. This test setup can be easily identified by employing readily available commercial test equipment. The TAS 4600 offers the capability to set parameters such as loc (signal-to-noise) value, lor/loc (channel power) value, and carrier-to-noise ratio. These parameters play a significant role in establishing accurate and reliable forward channel power.

The TAS 4600 enables careful monitoring and consideration of the output power level. Ensuring precise output power becomes particularly important due to the absence of a direct connection between the base station emulator and the device under test. The carrier frequency, which needs to be entered into both the TAS 4600 and TAS 4500 RF Channel Emulator, can be calculated based on the channel number, N, using a specialized equation. Moreover, the TAS 4600 is compatible with a dual junction circulator, which serves as an interface to the duplex port on the mobile phone. It is vital to utilize the high isolation junction of the dual junction circulator between the phone and the emulator. This precaution is necessary to prevent intermodulation products resulting from a high-powered signal leaking back into the emulator. However, the dual junction circulator's excellent isolation capability guarantees minimal leakage of mobile transmit power back into the emulator, ensuring optimal performance.
