P25 Phase II
Off Air Monitor Software for P25 Message Logging - Protocol
Analysis Tool (390XOPT230)
The Aeroflex 3900 Series P25 Off Air Monitor (OAM) is used to
capture and view APCO P25 messages sent over the air. The OAM
can receive and demodulate P25 RF signaling, decode P25 messages
and log these messages to a file for later viewing. Both trunked
(control and traffic) and conventional channels are supported,
allowing network engineers to:
• Verify compliance to P25 standards
• Troubleshoot existing P25 systems
• Analyze third party signaling
This option is a PC application that, using the data from option
390XOPT206, performs an advanced decoded display and log of the
XML data streams from multiple P25 channels. This provides the
user with the data to perform a complete analysis of all channels of a
P25 trunked system.
P25 AES Encryption (390XOPT240)
With the addition of this option, the 3920 supports P25 encryption
formats and manual key entry for systems that employ DES OFB
Type III (included in 390XOPT200) or AES encryption
(390XOPT240). These options allow decoding of encrypted voice
frames to verify encrypted channel performance. Encryption keys
may be loaded manually using either the front panel or external
keypad or with option 390XOPT209, keys may be loaded with the
Project 25 Key Fill Device (KFD) interface protocol. Additionally, keys
may be loaded using KVL ASN mode of operation found in KVL-3000
and older model key loaders from Motorola.
X2-TDMA Test Suite (390XOPT219)
Available for testing X2-TDMA test systems, this option is available
through Motorola only.
X2-TDMA Mobile Emulator (390XOPT245)
This option enables the testing of X2-TDMA base stations. This
option is available through Motorola only.
X2-TDMA Advance Test Suite (390XOPT261)
This option combines 390XOPT216 and 390XOPT245.
MOTOROLA HPD TESTING OPTION (390XOPT300)
• Generate/receive HPD signals
• Modulation - 64QAM, 16QAM and QPSK (inbound and
outbound)
• Transmitter parameters including signal power, frequency error,
EVM
• Symbol clock error, RX BER, burst timing error and occupied
bandwidth
• I & Q modulation analysis including constellation and trajectory
plots of the data symbols, synch and pilot bits
• Display of Min/Max and average as specified by the number of
bursts
• Pass/Fail indication using color code meters
Aeroflex has developed this test mode for Motorola to address the
need for testing their high performance packet data operation on both
mobiles and base stations in the 700 and 800 MHz bands. HPD
systems operate within the normal 25 kHz mobile radio bandwidth.
The 3920 HPD options provide users with the ability to test High
Performance Data systems. HPD can be configured for two modes of
operation. When configured to operate in BR Mode the test set
simulates base radio operation and is used to test the functionality of
Motorola HPD Mobile Subscriber Units (MSU). When configured to
operate in MSU Mode the test set simulates Mobile Subscriber Unit
operation and is used to test the functionality of Motorola Base
Repeaters (BR).
