The SPM-32A, SPM-33A and SPM-36A Selective Level Meters are hand-held instruments for selective and wideband measurements on FDM transmission systems with up to 600 channels.When combined with the PS-33A Level Generator (2 MHz), each of the instruments forms a test setup for measuring level, gain, attenuation and crosstalk. The test setup is the ideal tool for verifying the local loop performance
of services such as ISDN, PCM and xDSL.
