BVS YellowFin Remote Manager Software
User Manual
INTRODUCTION
The YellowFin Remote Manager (YFRM) runs on a Windows Vista based PC that is
connected to a BVS YellowFin system remotely. This connection is made through TCP/IP.
Through this connection, a YellowFin can be controlled. The YellowFin can be set to any
mode and settings available. Data can be monitored in real-time and stored in a relational
database for later viewing and reporting.
WiMAX Channel Scan Mode
INSTALLATION
Two applications are needed to use the complete functionality of the Remote Manager.
One is the Remote Manager software and the other is SQL Server Express, a free application
from Microsoft.
The Remote Manager software can be installed from the software CD. .NET Framework
needs to be installed on the computer in order for RM to function correctly. This framework is
already installed on all computers loaded with MS Windows Vista. If the YFRM will not run,
install the framework from the CD or from www.microsoft.com.
When using databases to generate reports, SQL Server 2005 must be installed on the
2
computer. SQL Server Express 2005 is located on the CD and may also be found at
www.microsoft.com. SQL Server is the database engine through which the YFRM
creates/adds and reports on data from the YellowFin.
SYSTEM REQUIREMENTS
Below is the minimum system requirements needed to run the full Remote Manager system.
Supported Operating Systems:
Processor Speed:
Memory:
Hard Drive Space:

REGISTRATION CODE
The first time that Remote Manager is run, a dialog box will show up asking for the
registration code. This code is located on the paperwork you received from the factory.
Each unit has its own registration code that is unique to the serial number. This registration
code is tied to the serial number of the YellowFin hardware. The code will be verified upon
connection to the hardware. The Remote Manager must be connected to the YellowFin unit
when running the application in order to verify the registration code. The Remote Manager
asks the hardware for its serial number. If it is not talking to the hardware, the registration
code cannot be verified and the application disabled.
QUICK START
DEVICE CONNECTION
In order to receive data from the YellowFin, you must first make a connection through the
network. See “Opening a Connection” below for details on this process.
DATABASE CONNECTION
In order to begin saving data to a database and have the ability to generate reports, you must
first create the database and then open it. Please see “Opening a Database” below for
instructions on how to do this.
DEVICE INTERFACE
HARDWARE REQUIREMENTS
In order to connect to a YellowFin unit, the hardware must be configured with the optional
Ethernet adapter and installed per the instructions. The YellowFin must also be powered by
A/C when using this adapter.
OPENING A CONNECTION
Click 'Open' from the 'Connection' menu to pull up the Connection center.
3
Connecting to a YellowFin
VIA LAN
If you are connecting to a YellowFin through an internal network (LAN), you simply need to
know the IP address that has been assigned to the Ethernet adapter connected to the device.
The port is typically 10001 and does not have be changed. If you are unsure of the IP address
but know the MAC address of the adapter (usually visible through the casing of the adapter),
a search can be made for devices. Clicking on the search button will list (after 5 seconds or
so) any MAC addresses the Remote Manager thinks may possibly be a YellowFin.
Choosing the correct MAC address will place the IP address in the lower box. Make sure that
the IP address matches the subnet of your network or you will not be able to make a
successful connection. If not, please use the “Set IP Address” option. Click 'CONNECT' after
populating the IP address box and the port. After a few seconds you will see the YellowFin
LED light up if a connection has been made.
WiMAX scan mode will be entered and the default channels will be scanned. If is is necessary
to change the IP address of the YellowFin, (for instance, if the address is not on the right
4
subnet) select the MAC address in question and choose “Set IP Address”. After doing this,
search for MAC addresses again to verify that the address has changed.
VIA INTERNET
If connecting to a YellowFin which is outside your local network, you need to find out the IP
address of the router which provides access to the hardware. Typically the router will have to
be configured to forward requests on port 10001 to the IP address of the YellowFin device.
Please see the instructions for your router. Entering the IP address of your router (make sure
it is a static IP address and not dynamically addressed), use port 10001. If the router is
configured correctly, you should be able to connect to the YellowFin through this port.
After clicking 'CONNECT' and waiting a few seconds, you will see the YellowFin LED light up
if a connection has been made. WiMAX scan mode will be entered.
If is is necessary to change the IP address of the YellowFin, (for instance, if the address is not
on the right subnet) select the MAC address in question and choose “Set IP Address”.
After doing this, search for MAC addresses again to verify that the address has changed.
CONNECTION STATUS
Choosing the ‘Status’ option from the Connection menu will provide basic information
after having connected to the YellowFin unit. Information such as serial number and firmware
version of the YellowFin will be provided.
5
Connection Status
WiMAX MODE
In WiMAX demodulation mode, the YellowFin attempts to demodulate any WiMAX signals
found on the specified channels. The channels specified are set using the channel list editor.
Channel List Editor
The channel list editor can be accessed by pressing the button in the channel list panel. Up to
16 channels can be placed in the list. The list can be saved to a file or restored from a file.
When the list has finished being entered, the user sends it to the YellowFin by pressing the
“Set As Current List” button.
6
WiMAX Scan Channel Mode
SCAN CHANNEL MODE
These channels will now be scanned in order. Each LED panel on the left will have a different
color. If a base id shows up on that frequency, a bar will show up in that color along with the
base id number and value in dB.
To view a single channel, click on the appropriate LED panel in the channel list.
7
WiMAX Single Channel Mode
SINGLE CHANNEL MODE
The list at the top of the screen will display any base ids that were found on the selected
frequency. If the base id has not been seen for a time period it will eventually fall off of the list
(see base id falloff).
The following fields are shown in the list:
•
ITEM – Item number in the list.
•
BASE ID # – Base id number from 0-113.
•
CINR – Carrier to Interference plus Noise Ratio.
•
RSSI – Received signal strength indicator in dBm.
All 114 base ids are shown in this mode. The stronger the signal, the greater the possibility that the base
id can be demodulated. Press 'Return to Scan List' to go back to scan mode.
8
SINGLE BASE ID MODE
A closer look can be made at each of the base ids in the list. Clicking on an item in the list will put the
YellowFin into individual base id mode. Only information from the selected base id will be displayed.
The RSSI screen shows the RSSI of the base id over the previous 20 seconds. Press the 'Return To
Channel' to go back to Single Channel mode. Press 'Return to Scan List' to return to Scan Mode.
WiMAX Base ID RSSI Mode
Choose different radio buttons in individual base id mode to view screens for CINR,Multipath, and
base id spectrum.

WiMAX Base ID Spectrum Mode
Base ID Falloff Settings
BASE ID FALLOFF
Choose this dialog from the WiMAX menu to adjust or turn off the base id falloff setting.
When enabled, the falloff setting will let base ids fall off of the single channel screen when not
12
seen after the time period set.
Bandwidth/FFT Size Selection
BANDWIDTH / FFT SIZE
Choose this dialog from the WiMAX menu to set the bandwidth and FFT Size for which
packets will be demodulated. The choices are 5MHz/512 and 10MHz/1024.
SPECTRUM MODE
By selecting the Spectrum tab, the YellowFin being controlled will switch from demodulation or
packet mode to spectrum analyzer mode.
13
Spectrum Analyzer Mode
Here the center frequency may be set. The span, start and stop frequencies can also be
selected.
REFERENCE LEVEL
This menu option allows the user to set the current reference level of the receiver. The valid
choices are between -20 and -70 dBm, in 10 dBm increments. The Reference Level should
be adjusted to obtain the greatest dynamic range. The Reference Level should be set so that
the strongest signal on the display is about 10 dB down from the top of the measurement
display. If a signal is drawn off the top of the measurement display or the message “clipped” is
displayed, lower the Reference Level. The highest Reference Level is –20dBm. The lowest
Reference Level is –70dBm.
RESOLUTION BANDWIDTH
The YellowFin measures the energy present in different frequency bins, each bin’s width
equal to the resolution bandwidth. The resolution bandwidth is set by setting the level for the
resolution bandwidth desired.
Why use a small Resolution Bandwidth?
A small Resolution Bandwidth is appropriate to measure frequency components and signal
characteristics. Smaller Resolution Bandwidths increases the Sweep Time (number of traces
displayed per second) for a given frequency span.
Why use a large Resolution Bandwidth?
14
A large Resolution Bandwidth is appropriate to measure large spans of frequencies quickly. A
resolution bandwidth larger than the signal’s bandwidth can measure channel power. The
YellowFin may be set to a large Resolution Bandwidth and a large Span to quickly sweep and
identify frequencies of interest. The Span and Center can then be decreased to measure
frequency components and the signal's characteristics.
SCREEN AVERAGE
The average of the last N sweeps will be displayed if the trace is put into AVG mode.
VIDEO SMOOTHING
Video Smoothing uses adjacent bin averaging to reduce the amount of fluctuation in the
measured trace due to noise. This is different from Screen Averaging, which averages the
same frequency bin from different traces. Use the arrows to increase or decrease the
bandwidth which are averaged for the smoothing. When properly set, Video Smoothing can
reduce the variation of the trace due to noise without distorting the trace. It is especially useful
for smoothing signals that are not continuous or repetitive. The user must use good judgment
when applying Video Smoothing. It is possible to smooth the trace too much so that the trace
no longer represents the spectrum of the signal.
TRIGGERING
Trigger Mode enables the YellowFin to quickly capture the spectrum from sources that are not
continuously transmitting. The trigger threshold represents the amount of CHANNEL POWER
that when exceeded will trigger the YellowFin to measure the spectrum. The trigger delay sets
a delay between the trigger threshold being exceeded and the measurement of the spectrum.
The trigger threshold is set by the user in dBm, and its range is from the current Reference
Level to 20dB below the current Reference Level.
NOTE: Span MUST be set to 20 Mhz.
Trigger Mode is very useful to capture the spectrum from any source that is not continually
transmitting on the same frequency.
TRACES
There are three available traces for display. By default, trace 1 is set to the live feed.
Each trace can be set to the following:
LIVE – Current real-time data will be displayed.
PEAK – The highest value recorded at each frequency will be displayed.
AVG – Video Smoothing and Screen Average results will display.
FREEZE – The last sweep will be displayed and frozen.
OFF – Trace will be turned off.
MARKER/DELTA
15
The marker menu option allows the user to place a marker at a certain frequency. The
frequency and power values are shown at the marker position. It also allows a delta marker.
This delta marker shows the difference in frequency and power from the marker.
To turn on the marker value and/or the delta marker value, simply tap the ‘ON’ button for
either value. Use the arrows to move the marker or delta value left or right across the screen.
Use the double-arrows to move faster. To center the marker on the screen, press the
‘CENTER’ button. To place the marker on the highest power value, press the ‘PEAK’ button.
To track the peak value, press the 'TRACK' button.
DATABASES
The data being viewed can be stored for later retrieval in a database. This data is then
stored into relational tables that can be formatted into reports on the information.
In addition to the simple reports that can be created using the Remote Manager, SQL Express
can be used to make even more sophisticated reports on the data stored in the database.
The following options can be found in the ‘Database’ menu.
CREATION
Choose a filename for your database. Database files can be up to 4GB in size. As the
database approaches this size, it will be necessary to create another database.
All appropriate tables will be created here. A popup box will tell you if the database has
been successfully created. If you receive an ‘Access Denied’ error, the current user does
not have permission through either Windows or SQL Server to create the database. If this
happens, you must check on these permissions.
OPENING
After a database has been created, it can be opened to collect data or to
generate reports on existing data. Choose from the list of databases found to be
registered with SQL Server.
If the database has been successfully created, the database LED will light.
CLOSING
When switching databases or deciding to stop collecting data, simply choose this option to
close the database.
REPORTS
After sufficient data has been collected, a variety of reports can be generated to
view the history of the information in WiMAX mode or spectrum mode. The
16
options for these reports are in the ‘Report’ menu and can only be accessed after
a database has been opened.
ENTRY FIELDS
FROM/TO DATES
Here the range of data can be selected. Choose times in which you would like to see the
data. Make sure to select a data range when data has been collected.
