1 ICROWAVE SYSTE ANAYZER E453//, E538// 70 Hz band 70/140 Hz band Custom-made product OPTION The E453 and E538 series are used to measure the transmission line characteristics in the BB and IF bands in terrestrial microwave radio relay systems and in satellite communication systems. The above types of transmission distortion can be measured and analyzed with them. They have been designed with special emphasis on measurement items, performance, functions, precision and size so that they can be used for all types of microwave radio relay systems, such as FD-F relay systems, high-efficiency large-capacity digital microwave radio relay systems, and INTESAT and other satellite communications systems. Unique special innovations contribute greatly to improving handling ease. To improve operational ease, a number of internal controls are used and some measurements are automatic. Furthermore, the measuring parameters and measured values are ed digitally, so even when one of these analyzers is used for the first time, results can be obtained quickly and accurately. The IF and BB frequencies must coincide for remote testing with other models or instruments of other manufacturers. This condition can be met quite easily by selecting the appropriate model from this particular series. ultiplexed telephone, TV, PC and data communications signals are mostly transmitted through microwave radio relay systems. However, when linear distortion (amplitude distortion, phase distortion) or non-linear distortion (which causes problems, particularly with analog signal transmission) is present in the transmission line, distortion noise is generated in the telephone transmission, clarity and color uniformity are lost with TV transmission and intersymbol interference between codes originating in the waveform distortion results in digital transmission. It is therefore necessary to measure the distortion in these transmission lines and to equalize it sufficiently. easurement items characteristics and sensitivity in modulators and demodulators Differential gain characteristics Differential phase characteristics IF and BB band amplitude response IF and BB band return loss deviation (or spectrum) A/P conversion coefficient DC characteristics IF/BB band power, gam, loss IF band frequency Applications The E453 and E538 can be used in the construction, maintenance, or research and development of digital microwave systems and of satellite 376 and terrestrial radio relay systems with BB and IF capability. The measurement item relating to the various circuit parts are listed below. odulators and demodulators:, sensitivity, group delay characteristics, differential gain, differential phase, IF and BB band amplitude characteristics Repeater IF sections and overall links: characteristics, differential gain, differential phase, IF and BB band amplitude characteristics Others: IF/BB i, power, gain, A/P conversion coefficient. The transmitter and receiver are designed to operate independently so that end-to-end measurement can be conducted with a single analyzer. RF band measurements can be conducted by connecting an up/down converter to this analyzer. Functions ED readout of transmitter settings For IF and BB measurements, the transmitter settings are shown with unmistakable clarity by the front-panel ED, so you can read deviation, sweep and center frequency at a glance. Automatic receiver settings and, IF level, and level all are automatically selected and ed by this receiver. Calibration and attenuation are also automatic. Automatic of units Both sensitivity and units are ed automatically for all measurements, so readings are fast and unmistakably accurate. All measurements shown on the CRT and large ED s easurement parameters and results are ed on the CRT in alphanumeric form together with the signal trace. They are also ed simultaneously on the large, easy-to-read ED. Signal averaging for noisy traces Internal normalizing circuitry allows you to average traces for removing the noise component as in the measurement of a satellite system, for example. BB to BB amplitude measurement (optional) An extremely flat baseband sweep generator and detector give you the end-to-end, BB to BB amplitude response measurements so necessary for maintenance of telephone and TV links. The CRT X-axis is a logarithmic frequency scale. arkers are at 60, 100 and 300 khz, and 1, 3, 10 and 15 Hz.
