Setting DSn Transmit Interface
3 If DS1 or DS3 is chosen, choose the required OUTPUT LEVEL.
4 If you have chosen 2 Mb/s as the SIGNAL rate, choose the required
TERMINATION. (At all other signal rates the impedance is fixed).
5 If you have chosen 2 Mb/s or DS1 as the SIGNAL rate, choose the
required LINE CODE. (At 34 Mb/s and DS3 coding is fixed).
6 If required, choose the FREQUENCY OFFSET value.
See “Adding Frequency Offset to the DSn Signal” page 33.
7 Choose the required PAYLOAD TYPE.
If is required must be chosen.
If is chosen the DSn test signal must be set up. See
“Setting Transmit Structured Payload/Test Signal” page 37.
If you have chosen 2 Mb/s, DS1 or DS3 as the DSn signal rate, the
Framed choice is expanded to provide a menu of framing types.
8 Choose the PATTERN type and the PRBS POLARITY.
