BitAlyzer Remote Control

Theory of Operation

BitAlyzer/BERTScope remote control enables operation of bit error analysis and physical layer tests via an IEEE-488 GPIB communications connection. Remote control is implemented using a text-oriented command protocol described in the following pages of this document. These commands set and query the system parameters of the Analyzer and operate the instrument in live error analysis and off-line 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 a specific operation or parameter within that feature, followed by optional parameters.

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.

It is most useful to have an understanding of the basic principles of BitAlyzer Error Location Analysis before undertaking remote control programming. There is a high degree of similarity between the BitAlyzer Analyzer graphical user interface and the remote control command protocol.

This document describes how to interface with the Analyzer using the IEEE-488 connection. The Analyzer is an IEEE-488 bus peripheral only; it is not an IEEE-488 bus controller and cannot produce SRQ signals.

Remote Control setup is accessed in the System view:

View > System > Tools > Remote > IEEE Address

Enter the unique address in the GPIB Address field.

For more technical assistance in programming your remote control applications, please contact Tektronix. We are glad to help.

Setting Up Remote Control

Touch Remote on the System view to launch the RemoteClient program. Touch the Disconnect to enable the IEEE Address button (this may take a few seconds). Touch IEEE Address.

You should now see the GPIB Configuration dialog. The Primary GPIB Address should be set to ‘3’.

Remote Control Protocol

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 “SYSTem:ERRor?” after each command. Besides telling you what has happened with the command, this will also synchronize command transmission and handling.

Command Syntax

Most commands have both a “long version” and “short version,” indicated by capitalized versus

lowercase letters. For example: GENerator:PATTern? can be typed out exactly as shown, or as

GEN:PATT? The capital letters and the colon (:) are required; the lowercase letters are optional. The

actual use of capital and lowercase letters is not significant – commands are not case-sensitive.

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

Every Command Line consists of two parts, a Command and <Setup Data> that are separated by a space and defined as ASCII texts.

<Setup Data> can be Double, Integer, or Boolean numbers, a file’s absolute pathname, a special word, or a Data Type. For a Boolean data type, the input can be 1 (ON) or 0 (OFF). The returned response will be either 1 for true or 0 for false. A question-mark character (?) is added at the end of a command, without a space, to create a Query.

When command setup data uses a string as a parameter, the string should be enclosed in double-quotes (“string”). Filenames always require the absolute path, enclosed within double-quotes.

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. A list of these codes is included below:

Error Codes Error Messages

0 "NO ERROR" "TOO MANY PARAMETERS"

-350 "Queue Overflow" "UNRECOGNIZED COMMAND"

-10 File transfer error "WRONG PARAMETER TYPE"

-20 System error or event "TOO LITTLE PARAMETERS"

-30 Command error; see list of error messages "WRONG PARAMETER FORMAT"

-40 No software option "WRONG PARAMETER NUMBER" "WRONG ACTION-ONLY" "WRONG QUERY-ONLY" "REQUESTED <QUERY PARAMETER> IS NOT SUPPORTED

ON THE PLATFORM"

Communications Timeouts

Most commands issued to the Analyzer are processed quickly and return within milliseconds. A handful of commands require considerable processing and take longer, including:

Detector Delay Calibration – 8 sec. (approximately) Generator Delay Calibration – 7 sec. Detector Auto-Align – 5 sec. Generator Data Signal Enabling (BERTScope only) – 7 sec. Run State Enable (Physical Layer Tests that perform initial auto-align) – 6 sec.

As a result, programming the communications architecture with a two-second timeout for most commands, and a 10-second timeout for the commands listed above is one approach. Another approach

is to set all communications timeouts to be 10 seconds. Of course, commands that don’t require this

much time will not be affected by the longer timeout, and this ensures that all commands can complete without triggering communications timeouts.

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.
