FEATURES
- HBT is a Bit Error Rate Tester for testing
synchronous modems and other DCEs.
- HBT operates at data rates from 32 kbps to 2.048
Mbps, including 1.544 Mbps, and supporting all n x 56 kbps and n x 64 kbps
data rates.
- When testing a DCE, a loop is performed, sending
the data back to HBT. HBT compares the received pattern with the
transmitted pattern and presents the result on an LCD display, counting
bit errors, sync loss number, block errors and error-seconds. HBT also
features an INJECT ERROR push button which enables the user to check the
tester and the line by introducing errors in the transmitted data stream.
- Five test patterns are available: 511
pseudo-random, 2047 pseudo-random, 7 space 1 mark, 7 mark 1 space and
alternating mark/space. Block size can be set to 512 bits, 1000 bits, 1024
bits, 2048 bits and 10 kbits.
- HBT can generate its own clock or receive clock
from the connected DCE.
- HBT supports the following interfaces: V.35, X.21,
RS-530, RS-232, G.703-2048 Mbps, G.703-1.544 Mbps and G.703-64 kbps by
means of field-replaceable modules (see Ordering). Module replacement is
straightforward and simple.
- Setup and operation are initiated from the front
panel using soft keys and interactive menu selection on an LCD message
display. Ten LED indicators display the activity of the interface signals.
- HBT is supplied in a convenient hand-held case. It
is powered by a detachable external power supply unit.
