Adding Jitter to PCRs The RTX130A provides the capability to add jitter to PCRs (Program Clock References). Adding jitter to PCRs allows you to simulate transmission delay variations and to test the robustness of decoders under various conditions. The jitter function adds jitter to the program_clock_reference_base value and the program_clock_reference_extension value in the adaptation field of transport stream packets.

Page 129: Figure 3-28: Example Of Scpi Subsystem Hierarchy Tree
This section contains information on the Standard Commands for Programmable Instruments (SCPI) and IEEE 488.2 Common Commands you can use to program your RTX130A. The information is organized in the following subsections: SCPI Commands and Queries SCPI is a standard created by a consortium that provides guidelines for remote programming of instruments.
Page 130: Table 3-15: Parameter Types Used In Syntax Descriptions
<pattern>. The parameter type is listed after the parameter and is enclosed in parentheses, for example, (discrete). Some parameter types are defined specifically for the RTX130A command set and some are defined by ANSI/IEEE 488.2-1987 (see Table 3-15).
Page 131: Figure 3-29: Example Of Abbreviating A Command
Syntax You can abbreviate most SCPI commands, queries, and parameters to an accepted Abbreviating Commands, short form. This manual shows these short forms as a combination of upper and Queries, and Parameters lower case letters. The upper case letters indicate the accepted short form of a command.
Page 132: Figure 3-31: Example Of Omitting Root And Lower-Level Nodes
Syntax If a command has the same root and lower-level nodes as the previous command, you can omit these nodes. In Figure 3-31, the second command has the same root node (REC) and lower level node (TARG) as the first command, so these nodes can be omitted.
Page 133: Table 3-16: Bnf Symbols And Meanings
ANSI/IEEE Standard 488.2 defines the codes, formats, protocols, and usage of Description common commands and queries used on the interface between the controller and the instruments. The RTX130A complies with this standard. The syntax for an IEEE 488.2 common command is an asterisk (*) followed by a Command and Query command and, optionally, a space and parameter value.
