Anritsu Company introduces three new options that make its award-winning BTS Master and Spectrum Master families the first complete TD-SCDMA handheld test solutions for deploying, installing, and maintaining TD-SCDMA networks now being deployed in China. With the options, field engineers, technicians, and contractors can accurately, quickly and easily make RF, demodulation, and Over-the-Air (OTA) measurements on TD-SCDMA signals.
The TD-SCDMA RF Measurement option offers a suite of test tools, including channel spectrum and power vs. time. The channel spectrum view shows the shape of the transmitter and displays the signal's channel power and occupied bandwidth. In addition, it displays the channel power and occupied bandwidth of the left and right channels. A power vs. time view displays the power over one frame of the signal, or can zoom into a slot selected by the user. In the frame view, individual slot powers are also displayed. Numerical results displayed include channel power, UpPTS (Uplink) power, DwPTS (Downlink) power, ON/OFF ratio, slot peak-to-average ratio and the Downlink – Uplink delta) power.
TD-SCDMA Demodulation measurements are used to measure the modulation performance of the selected Node B transmitter’s signal. With the demodulation measurement option, the BTS Master and Spectrum Master can display Code Domain Power (CDP) data screen and demod summary screens. The CDP data screen displays the power of the 16 codes of a demodulated TD-SCDMA signal. The code domain power and code domain error of the codes are displayed as a bar graph. Other measurement results include slot power; frequency error in Hz, EVM and Peak EVM; DwPTS power; Tau; noise floor; carrier feed through; and peak code domain error.
OTA measurements provide an easy way to monitor all 32 user codes outside a base station. Spectrum Master displays the codes in two convenient formats sorted by codes or by Tau, indicating distance from a base station. Code scan view displays all 32 codes in a bar graph with their individual Ec/Io and Tau. The code scan view also displays the DwPTS power and the pilot dominance. The Tau scan displays the code power in the Y axis and the Tau in the X axis. In addition, a table below the graph displays six of the strongest codes sorted by power. A convenient record feature where measurement data can be logged automatically along with GPS information is also available with the option.
All three options can be used with the MT8222A BTS Master, and the Spectrum Master MS2721B, MS2723B, and MS2724B analyzers. Weighing less than nine pounds, the MT8222A is the smallest, lightest, and most economical handheld solution for complete 2G/3G/4G base station testing. The MS2721B, MS2723B, and MS2724B are the most advanced ultra-portable 7.1 GHz, 13 GHz, and 20 GHz spectrum analyzers on the market, weighing in at less than 7 pounds. Their broad frequency coverage and excellent sensitivity, coupled with a wide selection of resolution bandwidths, make the MS272xB series well suited for the most challenging field environments.
The introduction of the TD-SCDMA test and analysis capability continues Anritsu’s commitment to providing test solutions designed to expedite the deployment of new technologies. Anritsu introduced the world’s first handheld WiMAX test solutions last year and also offers W-CDMA/HSDPA, GSM/GPRS/EDGE, CDMA2000 1X/1xEV-DO, DVB-T/H, and ISDB-T Analyzers.
Delivery is 4-6 weeks ARO at introduction and 2-4 weeks after two months.
