external frequency or phase reference input.
entrada de referencia de frecuencia y fase externa.

synchronizes the output wave in phase and/or frequency with respect to external signals (external frequency/phase reference).
sincronismo de la onda de salida en fase y/o frecuencia con señales exteriores (referencia externa de frecuencia/fase).

during the editing phase references act as url addresses, so that when you click on them, the cursor is brought to the place where the label is defined.
durante la edición, las referencias se comportan como si fueran direcciones url, esto es, al pinchar una referencia saltamos al lugar en el que está definida la etiqueta.

in particular, according to this document, together with the data processed by phase modulation and spectral spreading, a phase reference signal is also transmitted by direct sequence, said signal being obtained by spectral spreading with a second pseudo-randomsequence orthogonal to the first one and synchronous with it.
en particular, según este documento, junto con los datos procesados por modulación de fase y expansión de espectro, una señal de referencia de fase se transmite también por secuencia directa, dicha señal obteniéndose por expansión de espectro con una segunda secuencia seudoaleatoria ortogonal a la primera y sincrónica con ella.
