The phase noise measurement system controller NMSC-1 is provided with the NMS mainframe. The NMSC-1
controls all the measurement modules that are plugged in to the mainframe and includes a 1 MHz dual channel
FFT spectrum analyzer. The controller has a bright 6.4 inch color flat panel display. All functions of the
measurement system are available through a touch screen on the display. A keyboard and larger display
monitor can also be connected to the supplied SVGA and PS/2 connector. The NMSC-1 comes standard
with an Ethernet port, RS-232, and USB. Remote control of measurements and display of data is available
with an optional WLAN adapter. The measurement system software has been designed to hide the
complexity of amplitude and phase noise analysis and provide an intuitive user friendly interface. Access and control to all
measurement system settings is provided for the experienced user through lower level menus.
Noise measurements can also be made on pulsed RF signals by implementing the external triggering
option. The rising edge of a trigger signal turns on the IF amplifiers and initiates the data acquisition system.
The falling edge of the trigger signal turns off the data acquisition system and turns off the input to the IF
amplifiers. There are many advantages to turning off the IF amplifiers when there is no signal and only taking
measurements when the signal is present. For example, pulsed measurements can be made without limiting
the IF bandwidth of the system and avoiding many of the aliasing problems.
