cdmaOne and cdma2000 Measurement Views A number of different views are available from the view menu to enable the display of measured or calculated data. The views should be arranged within the main window before starting data collection or testing, although they can be opened and closed during a test.
Phone Based Measurements The E6474A software provides phone or PC Card based measurements for cdmaOne, cdma2000 and 1xEV-DO handsets or wireless PC Cards and is fully backward compatible with IS-95 handsets. The E6474A phone based measurements options provide 3 primary elements: Call setup Phone measurements Layer 3 messaging Call setup Call setup is divided into two main pieces –dialing setup and log mask setup.
- Loopback (13k) - Loopback (IS-126) - Markov (13k) - Markov (8k) - Markov (old 8k) - TDSO - Voice (13k) - Voice (IS-96) - Voice (IS-96A) Call Duration – length of the call Idle Time – time between calls Call Setup – maximum time allowed to make the connection Number to call – for a digital phone, enter the number to be dialed. For an analog phone, enter the speed-dial memory location that contains the number to be dialed. In answer mode, enter the phone number of the phone being called.
if checked, the phone’s Tx power will not vary as the BTS transmit power decreases, because the phone stops decoding the power control bit if unchecked, the phone operates normally Sounder Mode if checked, after the first call is placed and ended, only Sync channel messages will be received – no further calls can be placed or received if unchecked, the phone operates normally Force Reverse Link Voice to Full Rate if checked, transmit vocoder rates are set to the full rate, regardless of the

cdma2000 RLP statistics The radio link protocol, RLP, is a negative acknowledgement-based (Nack) protocol. This greatly reduces transmission errors over error-prone wireless links and therefore allows TCP protocol to function of wireless links. RLP statistics are key parameters that highlight the signal quality of the wireless link. These statistics are essential to identify and resolve data integrity issues within the air interface.

1xEV-DO Pilot Channel Analysis The Agilent E6474A system measures 1xEV-DO, cdma2000, IS-95 and J-STD-008 CDMA pilot channels. These measurements are independent of network parameter settings. The system executes four different types of CDMA pilot channel measurements (listed below). Any or all of them can be executed simultaneously.

base station transmitting PN offset 0 is expected to start a new short-code pattern synchronous with the GPS even second clock. If the signal is received 3 chips after the GPS even second clock, then the pilot delay is said to be 3 chips (1 chip ª 0.8 microseconds). Timing offsets can be due to both propagation delay and base station timing problems. Carrier frequency error is defined as the difference between the measured carrier frequency and the user-specified carrier frequency.
The 1xEVDO Receiver will accurately detect and identify PN peaks that have a delay from -31 to + 74 Chips (105 chip window) or a distance of approximately 11 miles, however Ec/Io accuracy will degrade with distance: PN Delay Ec and Ec/Io Accuracy -12 to +26 (Approx. 3.5 Miles) +/- 1dB -18 to +32 (Approx. 5 Miles) +/- 2dB -26 to +40 (Approx. 6 Miles) +/- 3dB -31 to +48 (Approx. 7.

Custom View Custom view gives the user flexibility to create customized views by selecting parameters required and displaying them in a tabular format. Up to 40 parameters can be applied per view and multiple views can be created and saved for reuse. Alarms view The Alarms view is used to configure alarms that are triggered by parameters received during a test that meet user-defined criteria.
• • Each parameter can generate its own sound when the criteria are met. Monitor a parameter that is collected as a text message and generate an alarm when the message changes. Configure multiple instances of the Alarms view. Use one for each device. Alarm configurations can be shared using export and import commands from the Alarms view. These alarm configurations are stored as .MSF files. The E6474A software is supplied with over one hundred predefined .MSF files.
on/off, y-axis scale display on/off, Draw method, Fill In Method and plot line colors. Route Map view The Route Map view shows current position and the route traveled on a map as data is collected. Several layers of information can be displayed, including signal parameters (selected via the Measurement Parameter view), survey markers, and notes. Basestation locations, with site names and sector orientations, can also be plotted on the map when linked to the appropriate cellsite naming database.
• • • Survey Markers - This shows Survey Markers that have been entered. Current Position - This shows current lat/long position. Signal - This shows the color code related to the ‘signal strength’ attribute and the letter associated with the ‘channel’ attribute as set-up via the Measurement Parameter view in signal properties. The number of signal buttons available depends on the technology of the tracking phone, to a maximum of three.
