Setting Up a PHS Bit Error Rate Test (BERT)
This section shows how to make BERT measurements on a personal handyphone system (PHS) radio using
the ESG Signal Generator with Option UN7.
The following procedures explain how to set up the ESG for making BERT measurements:
• “Connecting the Test Equipment” on page 265
• “Setting the Carrier Frequency and Power Level” on page 266
• “Selecting the Radio Data Format” on page 266
• “Setting the Radio to a Receiver Mode” on page 267
• “Selecting the BERT Data Pattern and Total Bits” on page 267
• “Selecting the BERT Trigger” on page 267
• “Starting BERT measurements” on page 268
Required Equipment
The following equipment is required to make BERT measurements.
• ESG Signal Generator, model E4438C with Options 001/601or 002/602, 402, and UN7
• an external controller to control the radio under test
• an interface level matching circuit for interfacing between the radio under test and the signal generator
when the radio signal specifications are different from those of the signal generator
