The CM750 delivers quick, reliable, repeatable manual and automated test
results in a features-rich handheld unit. Full analog and digital SLM functions
make the CM750 the most comprehensive troubleshooting tool available for
applications that do not require cable modem testing.
This versatile test unit can store and upload results over the network to a
PC or server for analysis or integration into back office management systems. An
Ethernet port enables fast network access for uploading results and downloading
configuration setup files. The CM750’s in-band capabilities and continuous
measurements simplify locating intermittent problems, and it provides complete
measurement detail for automated and manual tests. Easy-to-use pass/fail screens
indicate problems quickly, allowing immediate adjustments, replacements, and
follow-up verification tests.
