information. The type of signal at each output can be configured through a Web Interface to generate IRIG-
B004, DCF77, 1PPS, 1PPM, 100PPS, or any custom-defined low frequency, from 1 pulse-every-two-
seconds to 1 pulse-per-day. It is also possible to configure the outputs to generate daily set-time pulses. The
polarity of the signal can also be configured. For details on the configuration of optical outputs, see
Chapter
2.13 Amplitude modulated outputs
RT430 has 1 amplitude-modulated output, shown in
. It always generates IRIG-B124 signal.
