Anritsu has introduced new options for its BTS Master MT8222A and Spectrum Master MS272xB series handheld analyzers that expand their capability for measuring W-CDMA and HSDPA signals. The new options will allow field engineers and technicians to conduct W-CDMA and HSDPA measurements more quickly and efficiently when installing and maintaining wireless networks. Both instruments are capable of performing all the major RF and demodulation measurements on W-CDMA and HSDPA Over-the-Air (OTA) signals.
The new options enable the MT8222A and MS272xB to support HSPA+ 64QAM modulation, and to display a 64QAM constellation diagram on the measurement screen. The new software also adds support for discontinuous transmission (DTX) and Adaptive Multi-Rate (AMR). Furthermore, the speed of OTA scanner measurements now twice as fast as before, and improved Code Domain Power (CDP) measurement performance is now available due to lower EVM. More active channels can now also be displayed.
The MS272xB series ultra-portable spectrum analyzers feature a sensitivity of typically better than -153dBm displayed average noise level at 1GHz, allowing it to measure very low level signals. Three models are available: the MS2724B, which covers 9kHz to 20GHz; the MS2721B, with a frequency range of 9kHz to 7.1GHz; and the MS2723B with an upper frequency of 13GHz.
The BTS Master MT8222A is an integrated multi-functional basestation test tool that eliminates the need to carry and learn multiple test sets. Its measurement capabilities include spectrum analysis, precision return loss, VSWR, cable loss, distance-to-fault, two-port gain/loss, one-port and two-port magnitude and phase, interference analysis, spectrogram, RF and demodulation measurements.
