TRAFFIC CHANNEL LOGGING (DCS1>)
The Traffic Channel Logging port provides for logging protocol signaling from
the Traffic channel. Refer to Protocol Logging in the Application Guide.
Operating Considerations
• 9-pin sub-miniature D
• 115.2k Baud
•8 bit
• No parity
• No flow control
Pin assignments for this connector are as follows::
Pin 1 - Not Used
Pin 2 - RX_A, RS-232
Pin 3 - TX_A, RS-232
Pin 4 - Not Used
Pin 5 - Ground
Pin 6 - Not Used
Pin 7 - Reserved
Pin 8 - Reserved
Pin 9 - Not Used
16X CHIP OUTPUT
The 16X CHIP OUTPUT is a 19.6608 MHz clock output synchronized with the
1.2288 MHz chip rate that spreads the CDMA signal. The 16X CHIP OUTPUT is
phase-locked to the Test Set’s internal 10 MHz reference.
Operating Considerations
•BNC
• Nominal output level is >+5 dBm
• Output impedance is 50
Ω
• All frame clocks are locked to the Test Set’s internal 10 MHz reference frequency
stability is the same as the signal applied to the REF INPUT connector.
