1.3 Definition of Terms
Scanning
The System 7000 is said to be scanning after it has completed an “arm/start”
sequence and it is actively acquiring data.
Scan
A scan in the System 7000 refers to a single group of data that is acquired
simultaneously. For example, if you have 2 cards in your scanner (with 8 active
channels per card), a single scan consists of all 16 readings made at the same point
in time.
Note: Many instruments refer to a single group of simultaneously acquired data as
a “sample”, whereas, a “scan” is a collection of N samples. Notice the difference
in terminology.
Scan ID
The scan identifier is effectively a sequence number for each scan. The first scan
read is given a Scan ID of 1, the second scan has an ID of 2, and so forth. If you
know the scan rate, you then know the elapsed time at which the scan occurred.
(e.g. with a scan rate of 1000 scans/sec, scan 1 occurs at 0 mSec, scan 2 at 1mSec,
scan 3 at 2mSec, etc…)
Scan Rate
The rate at which scans are acquired. This can also be thought of as the sampling
rate.
I/O Card or AIM
Card
This refers to a Model 7003-8-A-I Analog Input Cards coupled with either a Model
7003-8-SG Strain Gage Input Card, Model 7003-8-HL High Level Input Card,
Model 7003-8-TC Thermocouple Input Card, or a Model 7003-8-LVDT Input
Card.
StrainSmart
StrainSmart is a software application, provided by Vishay Micro-Measurements,
that provides a comprehensive user interface for configuring the System 7000 and
managing data collection.
1.4 Document Notation and Conventions
1.4.1 Numbering Notation
