SPM33 PRODUCT OVERVIEW  
 

The compact, hand, battery-powered SPM-33 Selective Level Meter have been designed as multi-function in-service test sets for CF transmission systems with up to 300 voice channels.  The lower frequency limit of (50)200 Hz makes measurements in the audio and voice range possible.  From 50 to 200 Hz, measurements are possible but with lower accuracy and sensitivity.

Selective and wideband measurements of level and noise at balanced and coazial test points can be made.  If higher levels are to be measured, e.g. power line carrier systems, the necessary extrenal attenuator is available as an accessory.

The instruments can therefore handle practically all field tests thta are carried out during the installation, maintenance and monitoring of CF systems as operated by PPTs, the railways or public utility companies in the energy sector for example.
