Description:
 Provides signal conditions required by the 2715, 8591C, or AT2000R for accurate, in-service C/N, CSO and In-Channel Response tests (for in-service CTB tests, see the model 4200).
Allows in-service C/N and ICR measurements using any analyzer.
Eliminates the need for a tech in the headend during proofs.
Flexible; select any scan lines between 10 and 25 for tests.
Economical, allows installation on all test channels.
Can also be used as a line blanker to remove data in the VBI. |
Features:
Get maximum benefit from your automated test gear! The model 4100 provides the clean, consistent test conditions required by the 2715, 8591C, and AT2000R. No more problems caused by noisy in-coming feeds or lack of test signals for In-Channel Response tests.
Use any analyzer! The dynamic filter and high level multiburst signal in the 4100 provide accurate, in-service C/N and in-channel response test capabilities using the 2710, 2714, 8591C without option 107, or generic analyzers with no CATV specific features. Its even possible to perform these tests with some signal level meters!
No need for fudge factors! The 4100 allows you to run C/N and In-Channel Response tests at the output of set-top converters — as the rules require. No more inaccurate “correction factors” in an attempt to compensate for tests at the tap! Tests can be run under normal operating conditions, headend to subscriber terminal.
Run tests on scrambled channels! By running In-Channel Response and C/N tests at the output of the converter, tests can be conducted on scrambled channels — with the scrambler in service! This makes it much easier to select channels for proofs. It also reflects what the subscriber is actually receiving.
Monthly tests are a snap! If you use an analyzer with gated measurement capabilities (8591C opt 107, 2715 or AT2000R), you can leave 4100s in service year round. Run tests when and where you want!
Use different line numbers on different channels! Because a 4100 is installed on each test channel, you have all the flexibility you need to avoid undesired deletion of data or VITS. |
