The LNSW is a low-noise frequency divider switch that takes a 100 MHz reference signal, selected from one of three inputs, and divides it to provide outputs at 5 MHz, 10 MHz, and 100 MHz with exceptional low additive phase noise and minimal signal distortion. The instrument may be operated manually by setting the front panel switch to the manual selection position and turning the front panel rotary switch to select one of the three clock reference signals. When remote operation is desired, the toggle switch may be set to the auto position and the instrument can then be controlled
through the Ethernet port.
The LNSW is housed in a 1U, 19-inch rackmount enclosure and features four buffered and isolated outputs. All input and output power levels are monitored and compared to a set threshold of +7 dBm or a level defined by the user. If the signal level on any input or output drops below the set threshold, the monitor LED turns off indicating a fault condition, and the fault is reported through the Ethernet interface.
The LNSW features a redundant power supply system with alarm monitoring, enabling it to be powered by one or two 100-240 VAC mains sources. If the instrument is powered by two AC sources, the failure of one AC source does not interrupt its continuous operation, it only turns off the corresponding monitor LED and activates an alarm that will be transmitted via the Ethernet interface when the instrument is operated in auto mode
