635-1 QuickBERT Fluke Networks T1 Test Set

Model 635 is an affordable, full-featured QuickBERT-T1 from Fluke Networks®. Use this compact, handheld T1 test set for construction, installation and troubleshooting applications. In a single package, it provides all the basic T1 testing capabilities you would expect from a larger and more expensive tester. QuickBERT-T1 performs bit-error tests, detects framing type, line coding and bit pattern plus displays signal level, frequency, clock slips, errors and alarms. The 635 transmits the most commonly used loop codes including HDSL. Full, unframed and fractional (56 k and 64 k) T1 are supported along with display of signaling and data bits and capture of DTMF digits. In addition, 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. Model 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. SF, ESF, SLC96 and unframed framing also are supported.
QuickBERT-T1 is compact, rugged and easy to use. Just plug it in to see essential information immediately without scrolling through layers of menus. This test set detects framing and line coding type automatically and then displays any errors or alarms instantly. A history indicator helps track intermittent problems. Print test results and setup information.
Model 635 comes complete with two Bantam-to-Bantam cables, RS232 cable and trimmer tool to adjust LCD contrast, ToolPak™ Accessory Kit to hang test set, ac power adapter and user manual in a carrying case.
