Love heart 10 thousand | 9KHz–31.8GHz of analyzer of spectrum of Advantest U3771 30G

New portable spectrum analyzer has volume small, the characteristic with light weight, wireless signal can be measured inside microwave androwave and millimeter wave limits
Heart of love of Japanese company limited the lead company that 10 thousand tests are system of global semiconductor test, released U3771 of a kind of new portable spectrum analyzer on July 6, 2005 (frequency achieves 31.8 GHz) / U3772 (frequency achieves 43 GHz) , in congener spectrum appearance volume is the minorrest, weight is the lightest, can use batteries operation, can measure the microwave between station of mobile phone radical and millimeter wave signal are reached between orbiter.

Service of the 3rd acting mobile phone is expanding with cosmopolitan dimensions in, accordingly base the supportive network of the station also is expanding quickly. These base the antenna of the station wants a setting to be in the most accurate angle, so that change signal accurately. In addition, because of 20 GHz–The microwave belt of 30 GHz is deferent likely by physical fraise screen, so many base station setting is in the altitude such as high-level architectural housetop or summit. To undertake these base the setting of the station, examination and safeguard, requirement spectrum appearance has volume small, weight is light, portable characteristic.

The size of the U3771 / U3772 of portable spectrum analyzer with new Advantest is 308 Cm (W) X 175 (H) X 209 (D) , weight under 6 Kg, it is the smallest measurable 9 KHz on the world–The spectrum appearance of 31.8 / 43 GHz. Because developed new input way, bulk has the 1/2 of R3182 only. To suit field operation, u3771 / U3772 can use operation of AC/DC power source already, also can use be as long as the batteries operation of 2 hours. In addition warm-up time shortens, it is the 1/6 of old model about, make technical personnel completes the work OK and quickly, efficiently.

U3771 / U3772 realized miniaturization, light quantify, the design is exquisite, have worth while and pretentious complete test function, include the power of passageway power, channel of frequency, adjacent, test that has bandwidth. In addition, have function of high speed sampling more, measure repeatability to raise 0.01 DB, from this, can finish the power that need powermeter achieves before to measure with signal analyzer. And, because deployed fast response to spend input function (<-117 DBm @ 34 GHz: Typ) can take very faint signal, make can come true below all sorts of conditions outside the house inside house measure. U3771 / U3772 has LAN port, also have GB-IB interface, test data can be passed easily in the computer to have data government.
