System information

Chapter ‒ 30 Glossary
A
AMC
Audio mute concealment: an AXT400 receiver function that masks the small gaps in audio that may occur during frequency switching.
B
backup frequency
A frequency not currently in use but that the system can deploy to a device in the event of RF interference. If you are using a Spectrum Manager
(AXT600), the system can continuously monitor backup frequencies maintained in the Compatible Frequency List (CFL) to ensure that a clear and com-
patible frequency is available when needed.
band
A band is a standardized tuning range of frequencies. Transmitters and receivers are always associated with specific bands.
C
CFL
Compatible frequency list: contains all frequencies that are available for use by the system. The system can calculate the CFL using scan data, net-
worked equipment profiles, and exclusions. A Spectrum Manager (AXT600) can monitor and deploy frequencies in the CFL.
channel
Refers to a wireless audio channel formed by a receiver and a transmitter that are on the same frequency.
channel (group and channel)
A predefined set of hardware-specific frequencies that are coordinated to work with one another.
channel (TV channels)
A section of the RF spectrum (6 MHz in the U.S.) allocated to a digital television station. To avoid interference, you should not operate wireless devices
within the frequency range of a TV channel.
channel name
You can name audio channels to give them a unique identity. When you IR sync a transmitter with the receiver, both components share the channel
name.
channel strip
On the Monitor tab in Wireless Workbench, you can view a subset of parameters for a channel on a channel strip in a compact, convenient area.
D
device ID
A name for a device visible to other network devices and to Wireless Workbench. For Axient and PSM 1000 devices, the ID defaults to a model name.
device profile
Default tuning and coordination requirements associated with a device in Wireless Workbench.
DHCP
Dynamic Host Configuration Protocol: a network protocol used to automatically assign IP address to networked components. The AXT620 Ethernet
switch has an internal DHCP server to automate and simplify network set up by assigning IP addresses to DHCP-enabled components.
discovery
Wireless Workbench 6 automatically discovers and adds a device that is on the network. When a device comes online for the first time, Wireless
Workbench assigns a unique ID that lets the system recognize the device as it goes offline and comes back online.
E
Ethernet
The type of network used to connect networked components.
event log
A feature of the Spectrum Manager (AXT600) that records actions such as adding new equipment, serving a frequency to a receiver, or requesting a
scan. The event log provides a record of recent events and is useful for troubleshooting.
exclusion
When coordinating frequencies, you can exclude specific frequencies or frequency ranges from the Compatible Frequency List.
exclusion threshold
The system excludes scanned frequencies with a signal strength above this value from the Compatible Frequency List calculation. You can view and ad-
just the threshold while analyzing the scan data display.
