Analog Input The specification of the analog input channels, input
Configuration limits, input mode, and scan rate that Measure will use to
acquire a waveform.
Analog Output The specification of the analog output channels, output
Configuration limits, data points, and update rate that Measure will use to
generate a waveform.
analog trigger A trigger that occurs at a user-selected point on an incoming
analog signal. Triggering can be set to occur at a specified level
on either an increasing or a decreasing signal (positive or
negative slope). Analog triggering can be implemented either in
software or in hardware. When implemented in software
(Measure), all data is collected, transferred into system memory,
and analyzed for the trigger condition. When analog triggering is
implemented in hardware, no data is transferred to system
memory until the trigger condition has occurred.
AO Analog output.
array Ordered, indexed set of data elements of the same type.
Asynchronous A method of data communications in which information is
transmitted one character at a time. A start bit precedes each
character and a stop bit follows each character. The start bit
signals the beginning of the character transmission and the stop
bit indicates its completion. The Serial Add-In uses
asynchronous communications in its data exchanges.
Bbipolar A signal range that includes both positive and negative values–
for example, -5 to 5 V.
buffer Temporary storage for acquired or generated data.
Byte The standard method of representing numbers or characters in a
computers. Eight binary digits (bits) make up a byte.
