The HPD Service Monitor is connected with an HPD base radio to perform the following diagnostic
tests (for additional tests, see the HPD service monitor manual). These tests determine whether the
equipment is operating within specification. If the HPD base radio fails to meet specification, service
may be required. Topics covered include:
• Measuring HPD Base Radio Tx Power, Frequency Accuracy, and Tx EVM on page
• Measuring HPD Base Radio Rx Sensitivity and Rx BER on page
• Checking Receiver Sensitivity (Self-test Method) (HPD) on page 206
For additional information about using the service monitor, see the HPD Service Monitor manual or
online help (accessed through the Help button on the front of the service monitor).

Setting Up the HPD Service Monitor for Testing the Base Radio

Prerequisites: The test procedures require that the Rx and Tx cables of the base radio to be
connected to the HPD Service Monitor. Any calls present on the channel associated with the base
radio are dropped from that channel. The channel must be placed in Service Mode before performing
the test procedures so that the system does not attribute the loss of channel to a failure.
Procedure:
1 Plug a power cable into the AC port at the rear of the High Performance Data (HPD) service
monitor.
2 Connect a USB mouse to one of the two USB ports in the rear of the service monitor.
NOTICE: The following procedures assume that a USB mouse is connected. If not, for
instructions to click or select you can use the TAB key and arrow buttons on the front of
the service monitor. For instructions to select a soft key on the right side of the screen,
use the unlabeled buttons on the front of the service monitor, pressing the button located
next to the soft key on the screen.
3 Configure the Speed/Duplex setting in the PCs Ethernet interface to 10 Mb Half Duplex.
4 Connect to the base radio in Configuration/Service Software (CSS) through an Ethernet
connection. See Connecting Through an Ethernet Port Link on page
