ACTERNA TEST & MEASUREMENT SOLUTIONS SPM-32A/-33A/-34A/-35A/-36A Selective Level Meters Key Features • For line qualification tests on ISDN, PCM, xDSL, and measurements on analog transmission systems up to 3.5 MHz • Synthesizer for accurate, stable frequency settings • Straightforward operation with large digital display • Balanced and unbalanced inputs with common standard impedances • Battery operation up to eight hours Manufacturers, service providers, operators, and integrators qualifying copper lines require high performance instruments that will maximize testing efficiency and minimize training requirements for technicians. The JDSU SPM-32A, SPM-33A, and SPM-36A Selective Level Meters are handheld instruments for selective and wideband measurements on FDM transmission systems with up to 600 channels. When combined with the JDSU PS-33A Level Generator (2 MHz), each instrument forms a test setup for measuring level, gain, attenuation, and crosstalk. This test setup is the ideal tool for verifying the local loop performance of services such as ISDN, PCM, and xDSL. In addition to the basic functions, the SPM-34A Selective Level Meter also includes four special bandwidths for in-service measurements of FM-VFT systems, in accordance with ITU-T recommendations. With bandwidths all the way down to 5 Hz, the SPM-35A Selective Level Meter is ideal for analyzing composite signals. The instrument can be used for measurements on ARI and RDS systems, as well as remote control and FM-VFT systems as per ITU-T recommendations. WEBSITE : www.jdsu.com SPM-32A/-33A/-34A/-35A/-36A SELECTIVE LEVEL METERS 2 Accurate, stable frequency settings The built-in synthesizer and 1 Hz frequency resolution allows accurate, stable frequency settings across the entire range. This greatly simplifies tuning to pilots using a narrow resolution bandwidth. The instrument key, with user selectable step size, is useful for measurements on evenly spaced channels. Fixed frequencies such as pilots can be stored in the memory to speed up routine tests. Absolute and relative level measurements The digital display indicates absolute and relative level with 0.01 dB resolution, allowing measurements of very small level differences. The fast bar graph is very useful for alignment work. Straightforward operation The display provides a quick overview of all functions currently in use. Other functions such as frequency scan, AFC, demodulation, setups, and storage of fixed frequencies contribute to fast and error-free test procedures. Field application The instrument is ideal for such field applications as in-service testing and maintenance, due to its simple operation, wide temperature range, rugged design, and flexible options for powering – AC line or batteries.
