PowerDNA DIO-403  Layer 

-16- 

single-ended 

a term used to describe an analog-input 
configuration where you measure each channel with 
respect to a common analog ground. 

S/s, S/sec

 

samples/sec, samples per second 

system noise

 

A measure of the amount of noise seen by an analog 
circuit or an A/D when the analog inputs are 
grounded.  

T 

TCP/IP

 

  Transmission 

Control 

Protocol/Internet Protocol, 

the basic multi-layer communication protocol of the 
Internet but that is also used in a private network 
(either an intranet or an extranet). The higher layer, 
TCP, manages the assembling of a message or file 
into smaller packets that are transmitted and 
received by a TCP layer that reassembles the 
packets into the original message. IP handles the 
address portion of each packet so it gets to the right 
destination.  

throughput rate

 

The flow of data, measured in bytes/sec, for a given 
continuous operation. 

transfer rate

 

The rate, measured in bytes/sec, at which data is 
moved from a source to a destination after software 
initialization and setup operations; the maximum 
rate at which the hardware can operate.  

U 

UCT 

User counter/timer
