Test Instruments
CATV testing solutions for virtually every need. Like yours.
CATV technicians and engineers have relied on Trilithic filters and attenuators for their testing needs for many years. The wide selection of test instruments available includes products designed for special field and head-end testing requirements.
Several filter packages are available, including the VF series of tunable, field-portable bandpass filters, which provide pre-selection for accurate measurement of composite triple beat, cross modulation and other spurious signals.
Models are also available with built-in battery-operated preamplifiers, to further simplify testing at subscriber signal levels.
