18.1 Signal Overview
The Transmitter and Receiver configurations are grouped into a simple yet intuitive block diagram. The Tx and Rx signal
parameters can be modified by tapping the applicable block which brings up a new dialog window displaying additional input and
specific selection settings. The transmitter transmits as soon as a valid configuration is entered. The receiver will check for a valid
signal on its input so the measurement function is synchronized. When a test is not running, the LEDs will still indicate errors and
alarms, but any other results displayed will be the results of a previous test.
When the Tx and Rx signal structures are required to be identical or symmetrical, coupling the Transmitter and Receiver is
possible. The signal structure can be copied from Tx to the Rx, or vice versa.
Changes to Setup are applied immediately unless an invalid parameter has been selected.
When the Tx and Rx signal structures need to be independent or asymmetrical, uncoupling the transmitter and receiver is
possible.

18.1.1 Hierarchy
Tapping the Hierarchy box opens the Hierarchy Setup screen. The screen examples shown in this part of the manual depict and
describe the settings for 2M or E1 signals. The options for other bit rates and modes are described in text format.
High Rate:
In PDH mode, 2Mbit/s, Options are 34Mbit/s and 1.5Mb/s, 45Mbit/s.
Dual
(Rx only)
