About This Tutorial
This tutorial gives you an overview of the primary features of the E6701A GPRS Lab
Application. The tutorial explains how to
- Make a direct connection between the test set and a PC (not over an established LAN)
- Setup the test set and PC for the application
- Capture a screen from the test set
- Perform a PING
- Log protocol
- Use the Data Channel
Introduction
The Agilent Technologies E6701A Lab Application shortens the GPRS wireless appliance
design cycle with a one-box solution for parametric and signaling design validation.
The E6701A Lab Application (LA) is an option for the Agilent 8960 Series 10 (E5515B or
E5515C) Wireless Communications Test Set. With this option, R&D integration engineers
working on functional verification of GPRS wireless appliance firmware and hardware now have
access to a flexible, comprehensive, and easy-to-use one-box solution for quickly and accurately
validating a product’s parametric and signaling design requirements.
The Agilent 8960 Test Set, the industry standard for testing cellular handsets, now
accommodates many requirements of GPRS wireless appliance R&D engineers. The platform’s
new E6701A software retains the measurement and call processing capability of the E1964A
GPRS Mobile Test Application, which establishes a vital link between design and
manufacturing. The ability to use the same equipment in R&D and production allows for a rapid
and smooth transition from one phase in the product lifecycle to the next, as well as improved
troubleshooting processes.
The Test Set’s protocol logging capabilities facilitate testing and troubleshooting of new
signaling features and data channels, so engineers can extract better information about their
designs. Two-way IP data communication, when set up between a device and a network,
provides real data flow on a real data channel, enabling R&D integration engineers to test more
of the data handling performance of a GPRS device. Users of the E6701A can set timing advance
and cell parameters, which allows for testing and troubleshooting issues related to timing and
base station configuration.

Network Setup
This tutorial is designed around using a Local Area Network (LAN) which is also connected to
the Internet. Your PC or your test set may already be connected to this network. If it is
connected, you will need to know the address method used, and collect valid IP addresses for the
test set, the PC, and the wireless Device Under Test (DUT). You will probably want to contact
your Network Administrator in your IT department.
You will also want to know the network Subnet Mask and the network Gateway address.
Many LANs use a combination of static and dynamic (DHCP) IP addresses; others use only
static IP addresses.
LAN Addresses
Write the addresses you received from your network Administrator here:
Test set IP address: ___________________________
DUT IP address: ___________________________ (The DUT Address must be on the same
subnet as the test set address)
PC IP address: ___________________________
Subnet Mask: ___________________________
Network Gateway address: ___________________________
Test Set Setup
1. Turn on the test set or press the blue SHIFT key, then the green Preset key to reset it.
2. Press the SYSTEM CONFIG key. This displays the System Config Screen.
3. Verify the test application: GPRS Lab Application, E6701A, A.01.10
Note: version should be A.01.10 or higher. If not, some functions may be missing, or
may cause firmware malfunctions.
If the E6701A is not the active Test Application, switch it:
1. Press Application Selection (F3)
2. Press Application Switch (F1); wait a few seconds
3. In the table, use the knob to choose the GPRS Lab Application

Wait a few moments. The PC display will update as new data is captured in the Test Set.
Product Feature: Ping
Ping is a tool to help check system interconnects. Ping is only available in IP Data mode. The
Test Set uses Ping to send a 64-byte packet to the device being pinged. If the connection is
good, then the device will return a packet to the Test Set and the packet transfer information is
displayed on the Test Set’s screen.
Note: you can make a protocol log while performing a ping to a DUT (phone). (Note that the
Test Set can only log data that travels through the RF link, such as a DUT ping).

Product Feature: Data Channel
This is one of the most useful and powerful features of the E6701A. The Test Set acts as a GPRS
base station, for connection to one wireless appliance at a time, with complete connectivity
through to outside GGSN’s. (A GGSN provides the gateway between the GPRS network and the
public packet data network, also known as the Internet). This means you can quickly and easily
connect a wireless device to your choice of real Internet websites through a simple LAN
connection to the Internet.
You can also perform protocol logging during Data Channel operation. And even though IP data
is usually discontinuous, the E6701A allows you to make TX and RX parametric measurements
during Data Channel operation.
This tutorial uses a WAP (Wireless Application Protocol) browser built into the phone to show
how IP datagrams can be transmitted and received. Data will be exchanged using WML
(Wireless Markup Language), which is derived from HTML for wireless device use. Using the
phone’s WAP browser, you will connect to a WAP Proxy Gateway program running in your PC.
The WAP Gateway program will “pass through” the Internet addresses that you enter into the
phone’s browser, and will act as a go-between the phone and the Internet.
This tutorial uses the WAPlite Proxy Gateway.
To run the Infinite WAPlite Proxy Gateway software on your PC:
1. On your PC choose Start…Programs.
2. Choose the “WAPLite” directory
3. Select “WAPLite”. A window will appear with multiple tabs.
4. In the WAPLite window, select the “Options” tab
a. If your LAN DOES NOT use a firewall to access the Internet:
i. Check the box next to “Use HTTP Proxy Server”
ii. Other boxes on this tab should NOT be checked
iii. Type the name of a valid proxy server in the box next to “HTTP Proxy
Server” (You may find the name of your proxy server in Internet Explorer
Tools menu. Select Internet Options…Connections…LAN
settings…Proxy server. You should also consult your local IT department
for this information.)
iv. At the bottom of the tab, if the word “Apply” is in black letters, click the
“Apply” box (if grayed out, skip this step).
b. If your LAN DOES NOT use a firewall to access the Internet:
i. All boxes on this tab should NOT be checked, including “Use HTTP
Proxy Server”
ii. At the bottom of the tab, if the word “Apply” is in black letters, click the
“Apply” box (if in gray letters, skip this step).
5. On the “Stats” tab, click on “Install Service” to turn on the WAP Gateway software in
your PC.
With the WAPLite software running on your PC, external devices (like a phone) can
access this gateway server via the PC LAN port. The WAPLite server has one set of

On the Browser Menu, scroll to 2>Web Favourites with the up/down arrow key.
Press the OK key.
Scroll to http://local/waplite.wml
Press the OK key to GO. (The phone requests data from the device at the address above).
3. Watch the Test Set display.
At the bottom, in the Active Cell window, you can note the status will switch between PDP
Active and Transferring as IP datagrams are sent back and forth between the phone and the
WAPLite server on the PC.
4. Note the 3 sections of the display:
• Downlink power will flash a result each time the Test Set transmits to the phone.
• Counters track data packets and RACH’s.
• Error Reports continuously indicate the quality of the wireless appliance links.
5. On the device’s display, look at the downloaded image.
Motorola Timeport Example:
Use the scroll up/down key to read the text.
If you get a “web server error”, press the phone’s the OK key to go back to see the
image, and quickly scroll to see the text.
Press the 1 key 2 or 3 times to return to the browser menu.
Note: this WAPLite image and text is the only information accessible by a WAP browser
that is stored in the Infinite WAPLite gateway at installation.
6. On the PC, note that the Infinite WAPLite window shows one “Active User”, and now lists
some “Requests Processed”.
To browse “real” websites via the WAPLite gateway with the phone:
1. On the Test Set, press the Call Setup key.
2. Make sure the device is attached to the test set.

Appendix B: Troubleshooting
1. If the wireless device will not attach, check that:
1.1.
1.2.
1.3.
Cable loss is correctly specified in RF IN/OUT Amplitude Offset table
The SIM is good and installed correctly
Cell power is sufficient (increase it up to -35dBm to overcome interference, or if an
indirect RF connection is used between the Test Set and phone)
1.4.
Try Coding Scheme CS-1. Go to the Call Setup Screen; Call Parms column; Menu 2
of 4 (More key); Coding Scheme (F11 key)
1.5.
Maybe the wireless appliance is not capable of multislot configuration operation; if in
doubt, try 1 down 1up. Go to the Call Setup Screen; Call Parms column; Menu 3 of 4
(More key); Multislot Config (F7 key)
1.6.
This could relate to a connection parameter called TBF Frame Starting Position.
1.6.1.
Change this parameter under call parameters menu 4
1.6.2.
Try absolute or immediate frame starting position. The default is relative and
not all mobiles support this.
1.7.
Test Set displays IMSI warning:
GSM protocol warning; No IMSI received from MS
(Using default IMSI)
1.7.1.
This may be an error in the firmware of the phone.
1.7.2.
The default IMSI is 001012345678901.
1.7.3.
If this message is received, it is not possible to make a data connection unless
a SIM with the default IMSI value is installed in the wireless device.
1.8.
If you experience problems establishing a data connection specifically with the BLER
Data Conn Type:
1.8.1.
Try changing the setting of the LLC Frame Check Sequence from Valid to
Corrupt. Go to the Call Setup Screen; Call Parms column; Menu 4 of 4 (More key);
Connection Parameters (F4 key); scroll in Connection Parameters table to LLC
Frame Check Sequence.
1.8.2.
Try changing the setting of the BLER Block Polling Interval (default is 32;
range is1 to 32). Go to the Call Setup Screen; Call Parms column; Menu 4 of 4
(More key); Connection Parameters (F4 key); scroll in Connection Parameters table
to BLER Block Polling Interval.
2. If BLER mode measurements have problems:
2.1.
2.2.
Attach problem solutions still apply; see 1. Above
MS must be capable of GMM_INFORMATION messaging.
2.2.1.
This is the type of message we use to provoke an ACK/NACK from the
mobile.
2.2.2.
If the mobile is not capable of GMM information messaging, then the data
connection will timeout.
2.2.2.1.
One possible solution: set the LLC frame check sequence to Corrupt. This
will stop the message getting to GMM and the mobile should still provide the
ACK/NACK. Go to the Call Setup Screen; Call Parms column; Menu 4 of 4
(More key); Connection Parameters (F7 key); scroll in the Connection

Rev. 1.2; Feb. 14, 2002
Parameters table to LLC Frame Check Sequence; change the table value to
Corrupt.
2.2.3.
It is possible that the mobile is capable but GMM is prioritised too low and
the wireless appliance is unable to sustain the link.
2.2.3.1.
To get around this we can change the BLER block polling period. This
will allow the mobile to send the ACK/NACK less frequently(one negative
result: TX measurements will be slower since the mobile is not transmitting
every frame.) Go to call parameters, 1 of 4.
3. ETSI Test Mode measurements have problems:
3.1.
Check that the mobile is capable of the ETSI test mode you would like to use, if not it
will not work
3.2.
Check the same parameters as in Attach problems.
4. If the attach condition is terminated, this may be a Connection
Reconfiguration problem:
4.1.
This may be a Connection Reconfiguration problem. When any of the connection
parameters are reconfigured the connection is terminated.
4.2.
The mobile likely does not have the PACKET_TIMESLOT_RECONFIGURE
message implemented.
4.2.1.
This message is used to change MSTXL, channel, Band, Coding Scheme,
Multislot configuration, and offset P0.
4.2.2.
The solution when using the PACKET_TIMESLOT_RECONFIGURE
message is to stop the data connection before changing parameters, then restart the
data connection.
4.3.
Alternatively, you can change the message used to change parameters to
PACKET_DOWNLINK_ASSIGNMENT; or, for power changes use the
PACKET_POWER_AND_TIMING_ADVANCE message. Go to call parameters, 1 of
4.
5. If Internet Explorer cannot access the 8960 Welcome Page:
5.1.
Connections:
5.1.1.
Check that the LAN cables are good, and are properly connected
5.1.2.
If you are using the Test Set’s front panel DATA port: check that the LAN
jumper cable is attached on the Test Set rear panel between the LAN PORT
connector and the ETHERNET TO FRONT PANEL connector. (NOTE: For
minimum RF interference, Agilent recommends using the rear-panel LAN PORT
connector).
5.2.
Test Set:
5.2.1.
On the System Config Screen, check that the Application is GPRS Lab
Application.
5.2.2.
The Test Set LAN IP Address and Subnet Mask should not include leading
zeros.
Example:
111.22.333.44 is correct
111.022.333.044 is incorrect

5.3.
PC:
5.3.1.
Check that the network card (if present) is fully seated in the PC Card slot.
5.3.2.
Check that the LAN IP address in the PC is the same as the Test Set’s LAN IP
Address except for the 4th set of numbers (the last 3 digits).
IMPORTANT: Do not set the 4th set of numbers to 0. Also, do not set
the 4th set of numbers greater than 254.
6. The phone can’t access (browse) real Internet sites
6.1.
It can be difficult to “browse” WAP sites or other locations on the Internet because of
firewalls or other restrictions on a specific Intranet. Get help from your Network
Administrator.
7. BER measurement errors
7.1.
During Data Channel operation, the BER measurement DOES NOT function
correctly.
8. Phone won’t transmit IP datagrams in Data Channel functions
8.1.
Some older versions of Motorola Timeport phones may lose the IP address you have
entered. Check this whenever you turn on the phone.
9. When checking the IPCONFIG of your PC, multiple non-zero IP addresses
display
9.1.
Use the WINIPCFG utility program to help you troubleshoot.
9.1.1.
Choose Windows Start
9.1.2.
