What is a BERT test?
|
Bit Error Rate Test is a testing method for digital communication circuits that uses predetermined stress patterns comprising of a sequence of logical ones and zeros generated by a pseudorandom binary sequencer.
A BERT typically consists of a test pattern generator and a receiver that can be set to the same pattern. They can be used in pairs, with one at either end of a transmission link, or singularly at one end with a loopback at the remote end. BERTs are typically stand-alone specialised instruments, but can be Personal Computer based. In use, the number of errors if any are counted and presented as a ratio such as 1 in 1,000,000, or 1 in 1e06. |

Types of MSX Server Backups
|
Essentially there are two types of MSX backups: Online and Offline.
1. Online. MSX services are running with no impact to users. This backup offers the fullest recovery with respect to data loss. Two types of Online backups are used: Full Online—Backs up MSX Databases (public, private and directory) and MSX Transaction logs. Incremental Online—Backs up MSX Transaction logs only. 2. Offline. MSX services are stopped. Users cannot send/receive email or use Groupware features such as calendar, tasks, etc. This backup offers a “snapshot” restore. For example, if you are restoring MSX from a month-old Offline backup, your MSX server will have data only from the point the backup was taken (unless a subsequent online restore is laid over it). |

An effective welding technique for many bonding applications is the exothermic
mixture of aluminum, copper oxide, and other powders is held in place around the process. In this process, a joint with a graphite mold. The mixture is ignited and the bent generated (in excess of 4000° F) reduces the copper oxide to provide a homogeneous copper blanket around the junction. Because of the high temperatures involved, copper materials can be bonded to steel or iron as well as to other copper materials. |

What is a Continuity test
|
In electronics, a continuity test is the checking of an electric circuit to see if current flows (that it is in fact a complete circuit). A continuity test is performed by placing a small voltage (wired in series with an LED or noise-producing component such as a piezoelectric speaker) across the chosen path. If electron flow is inhibited by broken conductors, damaged components, or excessive resistance, the circuit is "open".

Bit Error Rate Test is a testing method for digital communication circuits that uses predetermined stress patterns comprising of a sequence of logical ones and zeros generated by a pseudorandom binary sequencer.

|
What is Signal-to-noise
|
Signal-to-noise ratio (often abbreviated SNR or S/N) is an electrical engineering measurement, also used in other fields (such as scientific measurement or biological cell signaling), defined as the ratio of a signal power to the noise power corrupting the signal. A ratio higher than 1:1 indicates more signal than noise.
In less technical terms, signal-to-noise ratio compares the level of a desired signal (such as music) to the level of background noise. The higher the ratio, the less obtrusive the background noise is. |

Bonding Conductor for Telecommunications
This conductor is used to bond the TMGB to the service equipment (power) ground which is in turn connected to the grounding electrode conductor. There are three important design considerations to remember about bonding conductors: |
• The copper core conductor must be insulated and be at least
No. 6 AWG in size • These conductors should not be placed in metallic conduit. If this can not be avoided, the conductors must be bonded to each end of the conduit if the run is longer than 1 m (3 ft) in length • Ensure that bonding conductors are marked appropriately by using a green label. |
