Operating Temperature:

Range of temperature in which output frequency and other electrical and environmental characteristics meet the product specifications. An operating temperature of 0°- +70° C is standard. Other operating temperatures are available and can be specified in the Oscilent Part Number Guide.
Storage Temperature:

The temperature at which the unit is safely stored or kept without damaging or changing the performance characteristics of the unit. The storage temperature is typically -30° - +85°, and is not a customer specified feature in Oscilent's product selection.

Storage Humidity:

The 5~95% @ 40°C, non-condensing

Vibration:

Vibration refers to mechanical oscillations about an equilibrium point. The oscillations may be periodic such as the motion of a pendulum or random such as the movement of a tire on a gravel road. Vibration is occasionally "desirable". For example the motion of a tuning fork, the reed in a woodwind instrument or harmonica, or the cone of a loudspeaker is desirable vibration, necessary for the correct functioning of the various devices. More often, vibration is undesirable, wasting energy and creating unwanted sound – noise. For example, the vibrational motions of engines, electric motors, or any mechanical device in operation are typically unwanted. Such vibrations can be caused by imbalances in the rotating parts, uneven friction, the meshing of gear teeth, etc. Careful designs usually minimize unwanted vibrations.
 

Shock: 

A mechanical or physical shock is a sudden acceleration or deceleration caused, for example, by impact, drop, kick, earthquake, or explosion. Shock is a transient physical excitation. Shock is usually measured by an accelerometer. This describes a shock pulse as a plot of acceleration versus time. Acceleration can be reported in units of metre per second squared. Often, for convenience, the magnitude of a shock is stated as a multiple of the standard acceleration due to free fall in the Earth's gravity, a quantity with the symbol g having the value 9.80665 m·s-2. Thus a shock of "20 g" is equivalent to about 196 m/s2. A shock can be characterized by the peak acceleration, the duration, and the shape of the shock pulse (half sine, triangular, trapezoidal, etc). The Shock response spectrum is a method for further evaluating a mechanical shock. It is sometimes used as a defense standard for military equipment.

EMC: 

A type of connector found on audio devices to attach a device, such as a microphone, for receiving audio. Line-out can be analog or digital.
