The SLM 1478 is designed to provide digital signal measurements from 4 MHz to 1 GHz. To isolate signal issues such as interference or noise, the SLM 1478 offers signal parameters including pre/post BER, average power, MER, spectral analysis, noise margin, and constellation for QAM A and B. In addition, the unit offers DOCSIS 3.0 capabilities for modem installation testing and both forward and return path analysis, as well as channel bonding.
The SLM 1478 provides a LAN port for network connections to facilitate FTP uploading of logged test data. A USB port provides channel plans and log file transfers for instrument cloning. The meter features pass/fail auto-inspect results (user definable), bar graphs, and improved spectral and constellation display resolution, plus an alphanumeric keypad for direct channel and frequency selection. The ergonomically designed front panel features display icons for setup and navigation. It's designed for field use, with a color display that is viewable in bright sunlight.
