This portable spectrum analyzer features a built-in standard preamplifier in a compact, handheld design that can go “anywhere, anytime”. Ideal for field environments and applications that require mobility, such as site surveys and on-site system testing. The MS2711D can be ordered with optional built-in transmission measurement that adds scalar analysis capability from 25 MHz to 2.5 GHz. It also features several dedicated smart measurements that make testing cellular, DCS/PCS and WLAN systems and other wireless systems easier than ever before. Measurements include received signal strength (RSSI), channel power, adjacent channel power ratio (APCR), and occupied bandwidth measurements that can confirm the distortion level or channel power level of an AMPS, TDMA, CDMA or GSM transmitter. Additionally, the MS2711D can locate and identify out-of-band spurious signals when analyzing a wireless base station transmitter, while the field strength mode allows users to measure propagation and coverage, or to pinpoint electromagnetic (EM) leakage in broadcast systems.
