JDSU/Acterna SPM36A Selective Level Meter 50 Hz to 3.5MHz
The Acterna SPM-32A, SPM-33A, and
SPM-36A Selective LevelMeters are
handheld instruments for selective
and wideband measurements on
FDM transmission systemswith up to
600 channels. When combined with
the Acterna 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.
