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.
