.
HOW TO: 1 Choose the required SIGNAL rate.
2 If you have chosen 2 Mb/s as the SIGNAL rate, choose the required
TERMINATION. (At all other rates the impedance is fixed.)
3 If you have chosen 2 Mb/s or DS1 as the SIGNAL rate, choose the
required LINE CODE. (At 34Mb/s and DS3 coding is fixed.)
4 If you are measuring at the network equipment monitor point, set the
LEVEL field to
. In this case the received signal will be 20
to 30 dB below the normal level.
Choose the GAIN required to return the received signal to normal.
Choose EQUALIZATION
to compensate for cable losses if
required.
