The Profile Settings section is similar to the Segment Manager section described in Advanced Waveform Editing
(on page 56). With respect to the Segment Manager case the component frequency can be provided only in
terms of Cycles, while the component amplitude must vary between ‐ 1 and 1.
The constant value amplitudes for the lateral interval are set by means of the Amplitude Inf and Amplitude Sup
indicators for the Low Frequency constant value and the High Frequency constant value intervals, respectively.
Profile Command
The following buttons are used for editing the Component List.
•
Add Component
Adds a component to the list. This component can be set for addition (or subtraction, multiplication, or
division) with others components in the list. An error message is shown when the Component List
exceeds the amplitude range.
•
Remove Component
Removes a component from the Component List.
•
Remove All Components
Removes all components from the Component List.
Digital Pattern Generator - Sampler (Optional)
Overview
ArbStudio can be configured to work as a powerful Digital Pattern Generator ‐ Sampler.
In this working mode ArbStudio 1102/1104 provides the capability to emulate standard serial or parallel bus
transitions or custom digital interfaces for system debugging and characterization.
The architecture is based on a vector/command memory and a powerful sequencer defining the
vector/command execution flow.
The Sequencer unit is a programmable finite state machine with a microcode memory that, combined with the
vector/command memory, can generate very long digital patters and control signals at a very high speed.
PLEASE NOTE THE FOLLOWING :
•
ArbStudio 1104D has 36 digital channels available, 18 CHs on Pod A and 18 CHs on Pod B.
•
ArbStudio 1102D has only 18 digital channels on Pod A.
As a Digital Pattern Generator ‐ Sampler ArbStudio provides:
•
36/18 Channels @ 125 MHz with Per Bit Direction (up to 288 Digital I/O with Expansion Bus)
•
2 Million Vectors in Generation
•
2 Million samples in Acquisition
•
Digital Waveform Sequencer
•
31 Levels Programmable Event Detector
•
2 Bank Programmable I/O Levels
•
Multi ‐ device synchronization with Expansion Bus
