1. Preparing for Use
There are three test modes for the MANUAL TEST mode:
o Synchronous mode: Tests are made while the Test Set and the mobile are
networked to communicate with each other. This is used to test mobile
phones during the Talk/RF Test step of a test flow, in a real-time manner.
o Asynchronous mode: (requires Option 002) Tests are made without
networking the Test Set and the mobile phone with each other. This is used
to test the RF transmission characteristics of mobile phones in a real-time
manner. Therefore, the receiver related characteristics such as sensitivity,
RX quality and level are not measured.
o GPRS mode: (requires Option 040) General Packet Radio Service (GPRS)
is a GSM data service that provides higher data transfer rates. Tests are
made while the Test Set and the mobile are attached to communicate with
each other. This is used to test mobile phones during the Attached step of a
test flow, in a real-time manner.
Table 1-1 Test Items available for Test Modes
• The SPECTRUM MONITOR mode (requires Option 002) allows you to
measure each radio channel’s spectrum transmitted from a mobile phone. The
spans for 0 to 400 kHz and ±100 kHz, relative to the traffic channel frequency,
are provided.
• The SIGNAL GENERATOR mode (requires Option 002) generates an RF
signal with or without modulation by a PN9 pseudo-random binary sequence or
all-zero data.
