DS200ITXDG1ABA Dynamic Brake Buffer Plate Specifications

The single plug-in connector that can be used to assemble this DS200ITXDG1ABA Dynamic

Braking Buffer Board is also fully discussed in the associated General Electric instruction manual material.

This connector is accompanied by a DBPL factory printed naming label and

connects this DS200ITXDG1ABA product to the accessible IMCP cousin PCB product in the larger Mark V series automatic drive assembly.

For convenience, the plug-in connector location for this DS200ITXDG1ABA PCB is described separately in the available guidance material.

Before making any single final purchase decision on this DS200ITXDG1ABA Dynamic Brake Buffer Board,

it is important to realize that it was originally designed to be used as a dynamic brake buffer board.

It is important to realize that the performance specifications and dimensions it

was originally introduced with have undoubtedly changed as a result of its receiving a full triple revision history.

The ITXD board allows for adjustment of the various outputs in the Mark VI series.

There are three different connector types on the board, allowing the board to be connected in a variety of different ways.

This DS200ITXDG1ABA printed circuit board product or PCB for

short has the normal style of Mark V series assembly, although it has been edited

by accepting the full range of three Mark V series feature and illustration configuration product revisions.

DS200ITXDG1ABA Dynamic Brake Buffer Plate Hardware Tips

Hardware Tips and Specifications

The required operation of the IXTD board is provided through the circuitry

of the connected power supply/interface board (IMCP).

When the IMCP and the IXTD board are connected, they are connected via a four-pin connector.

When the board is installed, it will be externally mounted and must

be sized to meet the worst-case switching requirements of dynamically braked IGBTs.

The purpose of the snubber board is to be used to limit voltage transients

​at both ends of the IGBT and at all known operating conditions of the driver.

Another function of the DS200ITXDG1ABA board is to regulate the output

of the IGBT gate driver board to match the electrical characteristics of the AT frame driver.

AT frame drivers are available in variable and constant torque applications.

The drive output current rating for variable torque applications is 500 ARMS.

The DS200ITXDG1ABA board has three connector types: bus I/O connectors,

input connectors for DBPL, and board pin connectors.

All of these connector types have different pin numbers, nomenclature,

and descriptions, which are explained in depth and in detail in the 

DS200ITXDG1ABA instruction manual included above for your convenience.

Bus I/O connectors and pin I/O connectors are also oriented. 

Two examples of pins associated with the stab I/O connectors are the

E-6 and E-9 connectors, both of which are output connectors.

The E-6 connector is the DB IGBT gate signal and the E-9 connector is the connection for the external buffer resistor.

DS200ITXDG1ABA Dynamic Brake Buffer Plate

About the DS200ITXDG1ABA

The DS200ITXDG1ABA board is labeled as a Dynamic Brake Buffer Board and

is part of the Mark V Series manufactured by General Electric.

The Mark V Series, of which this DS200ITXDG1ABA product is a part,

was one of the last of General Electric’s Mark product line to incorporate

Speedtronic control system technology into its various products.

And since it was eventually discontinued many years after its initial release, it exists as a legacy product line.

This DS200ITXDG1ABA Printed Circuit Board, or PCB for short, is not an original development for

its specific Mark V Turbine Control System family of functional roles;

it is actually the DS200ITXDG1 Parent Dynamic Brake Buffer Board.

The DS200ITXDG1ABA PCB is conspicuously missing all three versions

of the three important product versions of the DS200ITXDG1ABA PCB.

The assembly of this DS200ITXDG1ABA PCB has been specifically

altered to utilize a Level A Major Function Revision, a Level B Minor Function Revision, and a Level A Drawing Configuration Revision.

VMIVME-5576 Fiber Optic Reflective Memory with Interrupts Product Overview


Product Overview

-The Reflective Memory concept provides a very fast and efficient way to share data between distributed computer systems.

VMIC’s VMIVME-5576 Reflective Memory interface allows data to be shared between up 

to 256 independent systems (nodes) at rates of up to 6.2 Mbyte/s. Each Reflective Memory board can be configured with up to 256 nodes.

Each Reflective Memory board can be configured with 256 Kbytes to 1 Mbyte of on-board SRAM.

local SRAM allows fast reads of stored data.

Write data is stored in the local SRAM and broadcast to other Reflective Memory nodes via a high-speed fiber optic data path.

Data transfers between nodes are software transparent, so there is no I/O overhead.

Transmit and receive FIFOs buffer data during peak data rates to optimize

CPU and bus performance and maintain high data throughput.

Reflective memory also allows interrupts to one or more nodes by writing to byte registers.

These interrupt (tertiary, user-definable) signals can be used to synchronize system processes or to follow any previous data.

Interrupts always follow the data to ensure that the data is received before the interrupt is acknowledged.

The VMIVME-5576 does not need to be initialized unless interrupts are used.

If interrupts are used, vectors and interrupt levels must be written to on-board registers and interrupts must be set.

Each node on the system has a unique identification number between 0 and 255.

The node number is determined by placing jumpers on the board during hardware system integration.

The node number can be read by software by accessing the on-board registers.

In some applications, the node number helps determine the function of the node.

Advantest Q8384 High-End Optical Spectrum Analyzer Sweep Function

Extensive Analysis Functions

Sweep Function

The Q8384 displays the optical frequency on the horizontal axis; this is ideal for measuring

the grid frequencies of standardized wavelengths specified by the ITU-T (International

Telecommunication Union Telecommunication Standardization Sector).

Measuring the noise figure of a fiber-optic amplifier The Q8384 improves the noise figure

of a fiber-optic amplifier by enhancing the dynamic range, polarization correlation,

level accuracy, linearity, and accuracy of wavelength resolution settings.

As well as applying curve fitting and other features, the Q8384 realizes

high-precision noise figure measurements at the touch of a button.

Since the Q8384 can accurately determine the ASE signal level of DWDM signals

that are multiplexed at 10-minute intervals.

Since the Q8384 can accurately determine the ASE signal level of DWDM signals

multiplexed at intervals of 50 GHz (0.4 nm) or narrower, it not only performs accurate noise figure measurements,

but it can also accurately measure the noise figure of DWDM signals multiplexed at intervals of 10 minutes.

It not only performs accurate noise figure measurements,

but also displays multiple lists of measurement results at the same time.

WDM Analysis Functions

The Q8384 can display up to 256 wavelength peaks and power levels of WDM signals.

It displays the deviation of the wavelength and power level from the

ITU-T channel spacing or reference signal as well as the absolute value.

Alternate Scanning Function

The Q8384 can display two sets of measurements under different setup conditions in two windows.

These windows are always rewritable using the Q8384’s alternate scan feature.

With this feature, users can make detailed measurements of signals in a specific wavelength

band while monitoring the entire wavelength region of the WDM system.

Advantest Q8384 High-End Optical Spectrum Analyzer Superior Fundamental Performance

Superior Fundamental Performance

10 pm High Wavelength Resolution The Q8384 achieves a wavelength resolution bandwidth

of up to 10 pm by using a newly developed monochromator system.

This makes it possible to measure and evaluate the sidebands of 10 Gbps intensity-modulated optical signals,

a task previously impossible with conventional spectrum analyzers.

20 pm high wavelength accuracy

Calibrated with the built-in calibration light source (option 25), the Q8384 achieves wavelength

 measurement accuracy of ±20 pm in the C-band wavelength range from 1530 to 1570 nm.

The Q8384 achieves wavelength measurement accuracy of ±20 pm in the

C-band wavelength range of 1530 to 1570 nm and ±40 pm in the L-band wavelength range of 1570 to 1610 nm.

It enables accurate characterization of laser diodes and filters used in DWDM transmission systems.

The Q8384 can also accurately measure the wavelength spacing of WDM signals

because of its ±10 pm wavelength linearity over the 1530 to 1570 nm wavelength range.

50 dB (±0.1 nm)/60 dB (±0.2 nm) Wide Dynamic Range

In DWDM systems, signals need to be WDMed at intervals of 50 GHz (0.4 nm) or less.

Separating and measuring these closely spaced signals requires an optical spectrum analyzer with excellent dynamic range.

The Q8384’s dynamic range of 60 dB or more at 0.2 nm makes it ideal for this task.

With a dynamic range of 50 dB or more at 0.1 nm, the instrument can support future DWDM systems with closer signal spacing.

+23 dBm (200 mW) high-power direct input The Q8384 can directly measure high-power

signals from fiber amplifiers or pump laser diodes without attenuation.
