Theory of operation

This document contains a comprehensive listing or remote control commands for the Tektronix BERTScope family of products. It includes commands for the different pl for each of those commands.

The remote control features enable operation of instrument processes remotely via an IEEE-488 communications connection. Remote control is implemented using a text-oriented command protocol that enable you to set and query system parameters, and to operate the analyzer in different modes, including live error analysis and ofﬂine playback of previously recorded error data.

The text-oriented commands follow a basic three-part structure, consisting of one word identifying the major feature being addressed, another word identifying aspeci The analyzer receives and operates on each command immediately. Command execution sets a status variable that may be queried by the user to determine if the previous command was successful. Alternatively, a mode can be selected in which these statuses are automatically returned after each command execution.

Getting started

Remote contro

loverview

The BERTScope analyzer and any connected BERTScope instruments can be controlled remotely via either an IEEE-488 or a TCP/IP communications connection or a host PC..

The remote computer via either an IEEE-488 or TCP/IP connection. It then routes the commands to one or more BERTScope instruments, connected to the BERTScope analyzer or host PC via USB.

If the local host is a BERTScope, then the BERTScope software gets a chance to handle the command ﬁrst. Any commands the BERTScope software doesn’t understand are sent to the BERTScope instruemnt software, which then controls the BERTScope instruments.

When a BERTScope instrument is connected to a BERTScope, you can inter-mix BERTScope and BERTScope instrument commands in the same script, program, or int are routed to the remote control software directly. In this case, using the BERTScope-speciﬁc commands will result in an error.

For most applications, a single BERTScope instrument is connected to a BERTScope or host PC. In this case, the BERTScope instrument is automatically detected and connected when the remote control software is started, and automatically disconnected when the remote control software is stopped. There is no need in this case to use the OPEN or CLOSE commands described later in

is section.

. The remote control software runs on either a BERTScope anaylyzer,

control software accepts text-oriented commands from a remote

eractive session. If the host is just an ordinary PC, then the commands

If more than one BERTScope instrument is connected (such as a DPP125C and

ne or more Clock Recovery instruments) to the BERTScope or host computer,

o the remote control software will not connect automatically. In this case, the Remote computer must issue a NAMES? query to discover the IDs of the connected BERTScope instruments, and OPEN the one desired before issuing control commands. If the Remote computer needs to control multiple BERTScope instruments, it would OPEN, control, then CLOSE one, then OPEN, control, and CLOSE another. The device that is OPEN is referred to as the current device throughout this document.

Remote control is implemented using a text-oriented command protocol described in the following pages of this document. These commands enable you to set and query the system parameters of the BERTScope instruments, and to retrieve measurements made by the instrument.

BERTScope Remote Control Guide 1

Getting started

Set up the inst

rument for remote control operation

Remote setup is a ccessed from the BERTScope Analyzer System View.

1. In the System view, under the Tools tab Utilities heading, click the Remote button to access the conﬁguration panel.

2. Before beginning a remote control session, it is necessary to start the Remote Client application, RemoteClient.exe, on the host computer.

If the host is a BERTScope, click the Remote button from the System View To ols page. If the host computer is a normal PC, then just execute the RemoteClient.exe, ﬁle.

3. If you are using GPIB to control the BERTScope, enable the IEEE Address button.

If the button is not enabled, click the Disconnect button; it might take a few seconds to enable the IEEE Address button.

4. Click the IEEE Address button and enter the required information into the NI-488.2 Settings dialog box.

Command description

Remote control communications are exchanged as ASCII strings over a LAN telnet (TCP port 23) between the host computer and the analyzer. Select a communications port to be used for access to the instrument's remote control operations. If the port is set to NONE, then remote control is disabled.

The input values of commands are checked against the same ranges as the user interface. If an input is received that is outside of this legal range, the input will be clipped and recorded in the status queue.

It is recommended that you request the status of a command by sending SYStemERRor? after each command. Besides telling you what has happened with the command, this will also synchronize command transmission and handling.

Getting started

Command synta

Remote Control Command Lines are deﬁned as ASCII text strings ending with ‘\r’ or ‘\n’.

The commands follow a basic three-part structure, consisting of one word identifying the feature of the BERTScope instrument being addressed, another word identi The feature and operation are separated by a colon, and the operation and parameter (if any), are separated by a space. The operation can be Double, Integer, or Boolean numbers; a ﬁle path name; a special word; or a data type. For a Boolean data type, the input can be ON, OFF, 1, or 0. The returned response will be either 1 for true or 0 for false. A question-mark character (?) is added at the end o

FEATURE:OPERATION PARAMETER

Commands and parameters are generally case-insensitive, with the notable exception of those requiring a case-sensitive parameter for the Standard names.

Most commands have both a “long version” and “short version,” indicated by capitalized versus lowercase letters. For example: typed are required; the lowercase letters are optional – commands are not case-sensitive.

Features

When command setup data uses a string as a parameter (a ﬁlename or path name, for instance), enclose the string in double-quotes (“string”).

For every command processed, an error code will be returned. If the command has a question mark (a query), the setup information is also returned.

The BERTScope remote control commands are divided into feature groups. The number of features per each group depend on the BERTScope product.

In the ﬁrst group are commands that handle device discovery and connection. You can use these commands anytime, even if a current device has not been selected yet (with the OPEN command). The NAMES, OPEN, and CLOSE commands are allpartofthisgroup.

A second group consists of commands for controlling and monitoring a particular BERTScope instruments. The current device must have been speciﬁed (using the OPEN command) before to using any commands in this group.

Operations

Read-only properties

Read-write properties

In addition to t to control the host computer display (VIEW, PTFILE, GUILOCKOUT), the run state (RSTATE, RDURATION), and the overall program conﬁguration (SCONFIGURATION, RCONFIGURATION, ISSTATUS, RSSTATUS). These commands primarily implement the functionality provided by the GUI Console buttons.

Queryareadablepropertybyappendingaquestionmarktoit(withnospace between the command and the question mark). For example:

CRS:OPEN?

returns the device name of the currently connected BERTScope CR. In most cases, the returned values are all capitalized.

Query a read-write property by appending a question mark after it.

Set a read-write property by adding an appropriate parameter. For example:

DPP:OPEN “DPP_1234”

selects the BERTScope DPP with the device name DPP_1234 as the current device, while

he various feature groups, several miscellaneous features exist

Write-only operation

Parameters

DPP:OPEN?

returns name of the device previously OPENed.

Question marks are illegal for write-only operation, and parameters may or may not be required, depending upon the particular operation. For example:

DPP:CLOSE

requires no parameters, but

DPP:RCONFIGDISK “D:\BitAlyzer\Configurations\mycfg.DPP”

requires the complete pathname of the BERTScope DPP conﬁguration ﬁle.

A parameter can be a double or integer number, Boolean (0 or 1), an enumerated data type, or a string.

When a command uses a string as a parameter, the string is enclosed in double quotes ( double quotes.

“string”). Filenames always require the absolute path, enclosed within

Getting started

Command status

Parameters are

generally case-insensitive, with the notable exception of

case-sensitive Standard names. For example:

CRC:STANDARD “123abc”

and

CRC:DELETESTANDARD “123ABC”

are specifying different user-deﬁned clock recovery standards.

The BERTScope instrument receives and operates on each command immediately.

The input values of commands are checked. If an input is received that is outside of the legal range, the input will be clipped and recorded in the status queue.

Command execution sets a status variable that can be queried by the user to determine if the previous command was successful.

Request the status of a command by sending:

SYSTEM:ERROR? or SYST:ERR?

This command retrieves items listed in the error status queue, in the format:

Command

Error messages

< n, “event/string” >

The status queue is ﬁrst in, ﬁrst out. It can contain up t o 100 error messages. If the status queue overﬂows, the last error/event in the queue is replaced with Error

-350, “Queue overflow”. When all errors/events have been read from the

queue, further error/event queries will return

To clear the status queue all at once, send:

error messages and codes

The following error messages might be returned:

"TOO MANY PARAMETERS"

"UNRECOGNIZED COMMA

"WRONG PARAMETER TYPE"

"TOO LITTLE PARAMETERS"

"WRONG PARAMETER FORMAT"

"WRONG PARAMETER NUMBER"

0, “NO ERROR”.

ND"

"WRONG ACTION-ONLY"

BERTScope Remote Control Guide 5

Getting started

Error codes

The following error codes might be returned:

0 "NO ERROR"

-350 "Queue Overflow"

-10 File transfer error

-20 System

-30 Command error, see list of error messages

-40 No software option

Communications timeouts

Most commands issued to the BERTSope/BitAlyzer are processed quickly and return within immediately. However a handful of commands might require considerable processing and take longer, including the following:

"WRONG QUERY-O

“REQUESTED <QUERY PARAMETER> IS NOT SUPPORTED ON THE PLATFORM”

error or event

NLY"

Detector delay calibration — 8 seconds (approximately)

Generator delay calibration — 7 s econds

Detector auto align — 5 seconds

rator data signal enabling (BERTScope only) — 7 seconds

Gene

Run state enable (Physical layer tests that perform initial auto-align) —

conds

6se

As a result, programming the communications architecture with a two-second

meout for most command, and a 10-second timeout for the above-listed

ti commands is one approach. Another approach is to set all communication timeouts to be 10 seconds. Of course, commands that don’t require this much time will not be affected by the longer timeout. This ensures that all commands can complete without triggering communications timeouts.

GSM - Stressed Eye Setup

GSM:STRess:EN

ABle <bool>

GSM:STRess:ENABle?

Set or retrieve whether the entire global stress feature is enabled. The entire stress feature includes jitter insertion of sinusoidal jitter (SJ), external sinusoidal jitter (EXSJ), random jitter (RJ), PRBS jitter (BUJ) and external high frequency jitter (EXHF).

There are commands to enable each individual stress insertion, such as GSM:SJitter:ENABle; however, unless the Stress Feature is enabled using this command, those individual jitter insertion enabling commands do not enable any jitter insertion. For example, if one sent a GSM:SJ:ENAB 1 without enabling the stress feature (query GSM:STR:ENAB? returns 0), the system merely caches the SJ Enable value. The next time GSM:STR:ENAB 1 is sent, the SJ is then enabled. After the stress feature is enabled, one can still enable or disable individual types of jitter insertion by sending the corresponding ENABle command.

This command corresponds to the Clock control’s “Jitter Insertion Enabled” menu item in the Generator view.

IfthelocalhostisaBERTScopeAnalyzer, then the Analyzer software gets a chance to handle the command ﬁrst. Any commands the Analyzer software doesn’t understand are sent to the stress combiner software, which then controls the BERTScope BSAITS125.

When a BSAITS125 is connected to a BERTScope Analyzer, you can intermix BERTScope Analyzer and stress combiner commands in the same script, program, or interactive session. If the host is just an ordinary PC, then the commands are routed to the stress combiner software directly. In this case, using the BERTScope-speciﬁc commands will result in an error.

For most applications, the BSAITS125 is connected to a BERTScope Analyzer or host PC. In this case, the BSAITS125 is automatically detected and connected when the remote control software is started, and automatically disconnected when the remote control software is stopped. There is no need in this case to use the OPEN or CLOSE commands described below.

If more than one instrument is connected to the BERTScope Analyzer or host computer, the remote control software will not connect automatically. In this case, the Re mote computer must issue a NAMES? query to discover the IDs of the connected BERTScope instruments, and OPEN the one desired before issuing control commands. If the Remote computer needs to control multiple BERTScope instruments, it would OPEN, control, then CLOSE one, then OPEN, control, and CLOSE another. The device that is OPEN is referred to as the current device throughout this document.
