LOW NOISE SWITCH, 100 MHz
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 using the front panel switch. Setting the toggle to auto allows remote control of the instrument through the ethernet interface. The ethernet interface also allows continuous remote monitoring of the signal power levels and the device state. The LNSW is housed in a 1U, 19-inch rackmount enclosure and features four buffered and isolated outputs. It is equipped with dual AC power for redundancy.
