The JDSU / Acterna / Wandel & Golterman SPM-19 Selective Level Meter is used for carrying out the level, noise and phase jitter measurements that occur when balanced and coaxial FDM communication systems with up to 3600 speech channels are developed, manufactured, installed and maintained. The unit is also suitable for measurements at the lower multiplex level of single sideband radio-link systems, and on single telephone channels. The unit contains a synthesizer whose spectral features are low spurious modulation and high spectral purity. The frequency can be set via a keypad, tuned continuously, or tuned via step and automatic step facilities.
