VXi VT1422A 사용자 설명서

The Digital Signal Processor (DSP) chip that 
performs all of the VT1422A's internal hardware 
control functions as well as performing the EU 
Conversion process.

Same as Control Processor

Engineering Units

Engineering Unit Conversion: Converting binary 
A/D readings (in units of A/D counts) into 
engineering units of voltage, resistance, 
temperature, strain. These are the "built in" 
conversions (see SENS:FUNC: ...). The 
VT1422A also provides access to custom EU 
conversions (see SENS:FUNC:CUST in 
command reference and "Creating and Loading 
Custom EU Tables" in Chapter 3).

The First-In-First-OUT buffer that provides 
output buffering for data sent from an algorithm 
to an application program.

Flash or Flash Memory Non-volatile semiconductor memory used by the 

VT1422A to store its control firmware and 
calibration constants

This stands for Remote Signal Conditioning Unit. 
The VT1529A/B Remote Strain Conditioning 
unit is an example of an RSC.

A list of up to 512 channels that is built by the 
ROUTE:SEQUENCE:DEFINE command and 
analog input channels referenced in algorithms as 
they are defined. This list will be scanned each 
time the module is triggered.

Signal Conditioning Plug-on: Small circuit 
boards that plug onto the VT1422A's main circuit 
board. Available analog input SCPs can provide 
noise canceling filters, signal amplifiers, signal 
attenuators and strain bridge completion. Analog 
output SCPs are available to provide 
measurement excitation current, controlling 
voltage and controlling current. Digital SCPs are 
available to both read and write digital states, read 
frequency and counts and output modulated pulse 
signals (FM and PWM).
