General Description

The Axient Spectrum Manager is a powerful tool for calculating, analyzing and assigning compatible frequencies to wireless components. The Spectrum Manager scans the RF environment and uses this data to calculate compatible frequencies for all wireless channels found on the network. Networked wireless systems can be programmed from the Compatible Frequency List, while backup frequencies are continuously monitored and ranked according to quality. During operation, the Spectrum Manager deploys clear frequencies to receivers when interference occurs. Built-in spectrum monitoring tools provide visual and audio tracking of RF activity.

Features

Wideband Scanning

The Spectrum Manager captures scan data for the entire UHF frequency range available for wireless audio. The scan is compiled using two antenna inputs, with sensitivity and resolution that are directly applicable to wireless receivers.

Compatible Frequency List

The Compatible Frequency List (CFL) is list of available frequencies that can be calculated, viewed, and edited from the Spectrum Manager or it can be generated from a computer running Wireless Workbench® 6. The on-board frequency calculator can be adjusted to avoid specific TV channels, frequency ranges or RF signal above a specified threshold. During operation the Spectrum Manager provides current status of each frequency in the list. Clear frequencies are deployed from the compatible frequency list to initially setup a system or to replace frequencies degraded by interference.

Event Log

The Event Log records actions of the Spectrum Manager during operation. Actions include changes to frequencies and equipment controlled by the Spectrum Manager. Reviewing the event log after a performance provides a snapshot of system performance.

Backup Frequency Monitoring

The data screen tracks the status of all frequencies available for Axient systems. The number of frequencies is displayed for each band, including real-time status of in-use and backup frequencies.

RF Scanning

The scanning feature of the Spectrum Manager graphically plots the measured RF signal across the full frequency range. Cursor, Zoom, and Peak tools allow detailed inspection of the data.

Listen

Use the Listen feature to tune to a frequency and monitor FM demodulated signal using headphones. The data screen displays the signal strength for the selected frequency.

Networking

Networking enables many of the advanced features of the Axient system, including monitoring and control of remote devices. Rack components have two RJ45 Ethernet ports capable of 10/100 Mbps network speeds. The Ethernet ports are power over Ethernet (PoE) enabled to supply power to the ShowLink™ access point or other class 1 Ethernet devices.

RF Cascade Ports

The cascade ports allow sharing of RF signal with up to 5 components without antenna splitters or distribution amplifiers.

Networking a Spectrum Manager and Receivers

The Spectrum Manager uses an Ethernet connection to deploy frequencies to networked components. For automatic network configuration, use a DHCP enabled Ethernet switch such as the AXT620 or an Ethernet router with DHCP service. Use multiple Ethernet switches to extend the network for larger installations.

Note: For smaller systems, connect the Spectrum Manager and receivers using the Ethernet ports on the back panel. The devices fall back to compatible addresses if the IP Mode is set to Automatic and there is no DHCP server.

Automatic IP Addressing

  1. If using a Shure AXT620 Ethernet switch, set the DHCP switch to ON.
  2. Set the IP mode to automatic for all devices ( Util > Network > Mode > Automatic )

Manual IP Addressing

  1. Connect the Spectrum Manager and receivers to an Ethernet switch.
  2. Set the IP Mode to Manual for all devices:
    • Menu: Util > Network
    • Use the control wheel to set valid IP addresses for all devices. Set the subnet mask for all devices to the same value.

Troubleshooting

Use only one DHCP server per network

All devices must share the same subnet mask

All devices must have the same level of firmware revision installed

Look for the network icons on the display of each device:

  • If the icon is not there, check the cable connection and the LEDs on the network jack.
  • If the LEDs are not on and the cable is plugged in, replace the cable and recheck the LEDs and network icon.

Use the Find All utility ( Util > Network > Find All ) to view devices on the network:

  • The Find All report lists all devices on the network.
  • Check the IP address for devices not shown in the Find All report to ensure that they are on the same subnet.

To check connectivity of WWB6 to the network:

  1. Start WWB6 software and use Inventory view to see devices connected to the network.
  2. If not, find the IP address from one of the devices on the network (such as an AXT400 receiver) and see if you can ping it from the computer running WWB6.
  3. From a WINDOWS/MAC command prompt, type "ping IPADDRESS" of the device (e.g. "ping 192.168.1.100").
  4. If the ping returns success (no packet loss), then the computer can see the device on the network. If the ping returns failure (100% packet loss), then check the IP address of the computer to ensure it’s on the same subnet as the device.
  5. If the pings are successful and the devices still do not show up in the WWB6 inventory, check to ensure all firewalls are either disabled or allow the WWB network traffic to pass to the application. Check that firewall settings are not blocking network access.

Network Access Control

Access to Shure networked components can be controlled by setting a network PIN from Shure control software. Once a PIN has been set, the correct password must be entered from the software to make changes to component parameters.

Use the following steps to clear a network PIN:

  1. From the home screen: Util > Network > Access .
  2. Use the control wheel to select Disabled.
  3. Press enter to save.

Tip: Performing a Reset All will clear a network PIN; however, all parameters will return to factory settings.

Exclusions

Most RF environments contain frequencies where it is not desirable to operate wireless equipment, such as those reserved for local broadcasts, public safety, or other users. Exclusions can be entered into the Spectrum Manager to prevent it from including these frequencies in its calculation of a compatible frequency list.

Entering Exclusions

  1. Menu: CFL > New > Exclusions

  2. Press the menu button next to the Add option.
  3. Press the control wheel to highlight TV, Start, or Stop:
    • To exclude a single frequency, set the values for the Start frequency and the Stop frequency to the same value
    • To exclude a range of frequencies, use the Start and Stop values to define the frequency range
    • To exclude a TV channel, use the control wheel to set the channel number
  4. When finished, press ENTER to save changes.

    In this example, TV channel 32, the range of 599.00 to 604.000 MHz, and 650.000 MHz will be excluded from the compatible frequency calculation.

Spectrum Monitoring

The Spectrum Manager has built-in tools to provide an excellent resource for examining, tracking, and troubleshooting the RF spectrum.

Backup Frequency Monitoring

During operation, the data screen tracks the status of frequencies available for Axient channels in the system. The total number of frequencies available for each band are displayed, including real-time status of in-use and backup frequencies. Backup frequencies which have been degraded by the monitoring function are removed from the count of Ready frequencies.

  • In Use = frequencies that are deployed to Axient components including off-line devices
  • Ready = frequencies that are open and available for use as backups or for other components
  • More = select to view additional frequency bands

Listen

Use this feature to monitor the FM demodulated signal at a selected frequency.

Menu: Manual > Listen

  • Use the control wheel to select the frequency and antenna for monitoring.
  • The data display shows the signal strength of the selected frequency.
  • The menu display shows the selected frequency and antenna.
  • The Listen feature can also be accessed from the CFL > Edit menu, allowing easy cueing of frequencies that are in use or backups.

Scanning

Performing a spectrum scan creates a plot of RF activity on the data display. Use the Cursor, Zoom, and Peak tools to examine a specific area of the plot. The Store option allows for 2 plots of scan data to be saved by the Spectrum Manager for reference or for CFL calculation. Scans initiated from the Spectrum manager menu cover the entire tuning range. The Frequency Plot tool in Wireless Workbench software can be used to scan a subset of this range and provides options for step size and resolution bandwidth.

Menu: Manual > Scan

  1. Set the following modes:
    • Sweep = Single or Continuous
    • Peak Hold = Off or ON
    • Exclusion Threshold = The Spectrum Manager excludes scanned frequencies above this value from the Compatible Frequency List calculation. The threshold can be viewed during edit on the Scan Data display.
  2. Press Start to begin scanning. Scan progress is shown on the display. When finished press Store to save a scan. Select Recall to access a stored scan. The recalled scan will overwrite the current scan data.

The RF plot is shown on the Data Display screen.

Cursor Tool
