System information

P
parameter
Any adjustable setting on a device, such as frequency or gain.
peak hold
A plot feature that displays the highest recorded value for each frequency over the duration of the scan.
PoE
Power Over Ethernet: PoE-enabled devices, such as the ShowLink Access Point, use a single Ethernet cable for both power and data, eliminating the
need for separate power supplies.
pre-tonekey squelch
A headphone-monitoring option useful for troubleshooting. You can monitor audio from each channel prior to tonekey squelch and Frequency Diversity
processing.
R
RF cascade
The sharing of an RF antenna signal between multiple components. The system takes the RF signal from the RF cascade port of the first component
and feeds it into the RF antenna input of the next component.
RF history plot
In Wireless Workbench, a graphical representation of the RF signal strength measured over time, obtained from receiver antennas.
RF mute
Disables and enables the RF carrier signal from a transmitter.
S
scan data
Data obtained from a scan of the RF environment. You can view scan data on a frequency plot and save it to a scan file.
scan file
Lets you save scan data to a scan file to share, use later, and compare with other scan data.
show file
Lets you save inventory, venue location, device settings, linking relationships, and coordination to a show file that you can use later or share.
ShowLink™ Access Point (AXT610)
Enables wireless remote control of Axient transmitters.
Spectrum Manager (AXT600)
Monitors, analyzes, and assigns compatible frequencies to wireless components.
squelch
Receiver circuit that mutes the audio output of the receiver in the absence of the desired radio signal, using an adjustable noise threshold or the tonekey
signal from the transmitter.
subnet mask
Divides a network into smaller subnetworks. Use subnet masks to group and organize components for increased network efficiency.
U
user group
A user group is a country-specific set of frequencies designated for use by broadcasters (this feature is not used in the United States). Selecting a user
group ensures that only frequencies from this group will be calculated.
W
word clock
Synchronizes the digital audio of multiple components operating together in a system. The AXT400 receiver has an internal word clock, or an external
word clock may be used.
Z
zone
Allows efficient spectrum usage in high-channel-count applications where groups of transmitters are physically separated by location. You can use
zones when transmitters will be physically far enough away from each other that intermodulation products are not a concern, but still close enough that
having the same frequency is a concern.
