Description
<p>The Bit Error Rate Indicator is designed to be used with the Pseudo-Random Binary Sequence Generator, Model 9422 (not included), to measure the transmission error rate on a bit stream within a communication system, in order to assess the reliability of the communication path.
The module compares two data streams and counts, for a specific period of time, the number of non-identical bits. Three test durations can be selected: 1 s, 10 s or 100 s. Error rates can be measured within a range of 0.01 error per second to 9999 errors per second.
At the end of each test period, the error rate appears in errors per second on a 4-digit display. The display will blink in case of overflow. The counting cycle is automatically reset when another test duration is selected. Each new reading can be announced by a tone, which is useful for long test periods. This feature can be disabled at any time. The tone generator cannot be used for a test period of 1 s.
