Signal
RX Termination
Power indicates the received signal level in dBdsx for DSn or dBm for
PDH and SONET/SDH.
Amplitude indicates the received signal amplitude as well as its MIN,
and MAX received values.
TX Frequency
Note: The following TX Frequency information applies to serial interface only,
refer to TX Frequency on page 214 for parallel interfaces.
TX Frequency (GHz) indicates the frequency (actual frequency +
Frequency offset) used for transmission.
Offset (ppm) check box, when selected (cleared by default), allows
setting the frequency offset that will be generated. Use the “+” or “-”
button to respectively increment or decrement the frequency offset
value based on the defined Increment/Decrement Size, or directly
type the frequency offset value in the field. Possible offsets are:
