The Anritsu MS2687B is a microwave spectrum analyzer covering 9 kHz to 30 GHz, designed for evaluation of wireless LAN equipment and devices and a broad range of microwave measurement applications. The frequency coverage extends measurement capability up to fifth-order harmonics on 5 GHz Wireless LAN signals, and the instrument can be extended to 110 GHz through the use of external mixers from Anritsu's MA2741A through MA2746A series.
Applications listed for the MS2687B include evaluation of wireless LAN equipment and devices, installation and maintenance of radio stations, maintenance of microwave entrance lines, and development and production line testing of various high-frequency parts. The MS2687B addresses one-touch measurement of occupied bandwidth, channel power, and adjacent channel leakage power, and supports analysis of broadband signals through its wide resolution bandwidth.
ValueTronics International, LLC stocks, tests, and ships test and measurement equipment from our 20,000 sq ft secure warehouse at 1675 Cambridge Drive, Elgin, Illinois. Every instrument moving through our facility is handled by our team rather than drop-shipped from a third party, which means inventory is verifiable, condition is documented from direct inspection, and questions about a specific unit reach the technicians who actually evaluated it.
Anritsu Corporation is a Japanese precision measurement company with roots reaching to 1895. Anritsu's 1993 acquisition of Wiltron Company brought significant RF and microwave measurement technology into the Anritsu portfolio, and current Anritsu RF instruments trace much of their North American commercial presence to that combination.
