Fluke Networks 635 QuickBert-T1
- Full featured, handheld T1 test set at an affordable price.
- Instantaneous detection and display of framing, line coding, errors,
alarms, level, frequency and more
- Transmits and receives common Bit Error Rate Test (BERT) patterns
and includes all common loop codes, including HDSL Product Capabilities
The 635 is a compact, handheld T1 test set for construction, installation
and troubleshooting applications.
In a single 4 lb (1.8 kg) package, the 635 includes all the basic T1
testing capabilities you would expect in a larger and more expensive tester.
It performs bit-error tests, detects framing type, line coding and bit
pattern, and displays signal level, frequency, clock slips, errors and
alarms. The 635 transmits the most commonly used loop codes, including
HDSL. Full, unframed and fractional (56k and 64k) T1 are supported, along
with display of signaling and data bits and capture of DTMF digits. Plus,
individual voice channels may be monitored on the built-in speaker or
over a headset.
Eleven standard BERT patterns are available, including a 64-bit user-defined
pattern. The 635 also includes a "through" mode where the incoming pattern
is retransmitted. Errors - including bipolar violations, logic and frame
bit - can be injected to confirm proper handling by the network. Two receivers
permit detection of any clock slips. Multiple receiver input types allow
terminated, bridged or monitor (DSX) connections. Either recovered or
internal clock references can be selected. AMI or B8ZS line coding can
be transmitted and received, and SF, ESF, SLC96 and unframed framing are
supported.
The 635 is compact, rugged and easy to use. Just plug it in and you can
immediately see essential information without scrolling through layers
of menus. The 635 automatically detects framing and line coding type and
instantly displays any errors or alarms. A history indicator helps track
intermittent problems.
