Handheld spectrum analyzer tackles ultra-wideband signals
Anritsu Company's MS2721A handheld spectrum analyzer is RF Design's Product of the Month for July 2004.
Further extending its reach to conduct accurate analysis of a new wave of wireless signals, Anritsu Company has readied a fully functional, battery-operated spectrum analyzer that can tackle ultra-wideband signals up to 7 GHz anywhere, anytime. Consequently, the next-generation handheld spectrum analyzer MS2721A offers test solutions to measure 802.11a, 3G and WiMAX signals, in addition to public safety and military communications systems. Plus, it weighs 6.4 pounds, to make it comfortable on the engineering bench as well as in the field. By comparison, the previous-generation unit handled signals to 3 GHz.
According to Anritsu, the new handheld spectrum analyzer will enable developers to ensure integrity of data/voice transmission, while helping them to identify interfering signals. These analysis capabilities are becoming important with the rollout of new wireless infrastructures, wherein the RF signals are more complicated and at higher frequencies. Target markets for this high-performance spectrum analyzer include field service and signal surveillance, mobile wireless networks, wireless data/Internet, wireless broadcast, and military/aerospace.
In essence, the MS2721A covers signals in the range of 100 kHz to 7.1 GHz. It can make a variety of measurements with the push of a single button. Some of these include field strength, channel power, occupied bandwidth, emission bandwidth, adjacent-channel power ratio (ACPR), AM/FM demodulation, and carrier-to-interference ratio (C/I). Besides high performance, Anritsu also guarantees measurement accuracy. As a result, the spectrum analyzer offers a phase noise of -100 dBc/Hz at 10 kHz offset, dynamic amplitude noise level (DANL) of -152 dBm at 2.2 GHz (typical) and a resolution bandwidth range of 10 Hz to 3 MHz. Over and above, the instrument automatically sweeps at the fastest possible speed to get accurate data. Other features include an 8.4-inch TFT color LCD with wide viewing angle, external/internal compact flash slots, and Ethernet 10/100 and USB 2.0 ports. The instrument's LCD offers three colored display traces — one live, two stored.
For field use, the spectrum analyzer comes in a rugged case that can withstand harsh environments and rough terrains. The operating temperature range for the unit is -10°C to +55°C. Additionally, the spectrum analyzer incorporates a simple multilingual, customizable user interface in English, Spanish, French, German, Chinese and Japanese. To obtain long life and durability, it uses a Li-ion battery. The base price for the MS2721A starts at $15,950.
