Getting Started

The 3066 and 3086 are DC to 3 GHz Real Time Spectrum Analyzer. The instrument software operates on the Windows 95. You can write computer programs that remotely set the analyzer front panel controls or that take measurements and read those measurements for further analysis or storage through the GPIB or TCP/IP Ethernet (optional) interface.

To help you get started with programming the analyzer, this section includes the following sections:

H Overview of the Manual – summarizes the type of programming information

contained in each major section of this manual.

H Setting Up Remote Communications – describes how to physically connect

the analyzer to a controller and set the appropriate front panel controls.

The Difference between the 3066 and 3086

The 3066 and 3086 functions are the same, except that the 3086 has the following two input modes:

H Wideband input mode: Processes 50 MHz to 3 GHz signals with maximum

30 MHz span in the vector mode.

H IQ input mode: Inputs the I and Q signals directly from the rear panel

connectors.

The descriptions in this manual apply to both the 3066 and 3086, unless otherwise noted. For more information about the functions of the analyzer, refer to the User Manual.

Syntax and Commands

Command Syntax

This section contains general information on command structure and syntax usage. You should familiarize yourself with this material before using the analyzer command descriptions.

This manual describes commands and queries using the Backus-Naur Form (BNF) notation. Table 2–1 defines the standard BNF symbols.

Command Syntax

Commands and Queries

The analyzer commands are based on a hierarchical or tree structure (see Figure 2–1) that represents a subsystem. The top level of the tree is the root node; it is followed by one or more lower-level nodes.

Creating Commands

Marker

DeltaX

PeakX

Root node

LowerĆlevel nodes

Figure 2-1: Example of subsystem hierarchy tree

You can create commands and queries from these subsystem hierarchy trees. Commands specify actions for the instrument to perform. Queries return measurement data and information about parameter settings.

The analyzer commands are created by stringing together the nodes of a subsystem hierarchy and separating each node by a colon (:).

In Figure 2–1, View1 is the root node and Marker, X, DeltaX, and Peak are lower-level nodes. To create a command, start with the root node View1 and move down the tree structure adding nodes until you reach the end of a branch. Most commands and some queries have parameters; you must include a value for these parameters. The command descriptions, which start on page 2–7, list the valid values for all parameters.

2-2

Creating Queries

For example, :View1:Marker:X 1.5 is a valid command created from the hierarchy tree in Figure 2–1.

NOTE. If you specify a parameter value that is out of range, the parameter will be set to a default value.

To create a query, start at the root node of a tree structure, move down to the end of a branch, and add a question mark. :View1:Marker:X? is an example of a valid query using the hierarchy tree in Figure 2–1.

Command Syntax

Headers in Query

Responses

Parameter Types

You can control whether the analyzer returns headers as part of the query response. Use the [:Util8]:Header command (page 2–386) to control this feature. If header is on, the query response returns command headers and formats itself as a valid set command. When header is off, the response includes only the values. This may make it easier to parse and extract the information from the response. Table 2–2 shows the difference in responses.

Table 2-2: Comparison of header off and on responses

Query Header off response Header on response

:View1:Source? "FILE1.AP" :View1:Source "File1.AP"

:Setup:Span? 5M :Setup:Span 5M

Parameters are indicated by angle brackets, such as <file_name>. There are several different types of parameters, as listed in Table 2–3. The parameter type is listed after the parameter. Some parameter types are defined specifically for the analyzer command set and some are defined by ANSI/IEEE 488.2-1987.

Command Syntax

Abbreviating Commands,

Queries, and Parameters

Chaining Commands and

Queries

You must not

abbreviate all commands, queries, and parameters. For example, shortening the command :Setup:CenterFrequency to :Setup:CenterFreq causes an error.

You can chain several commands or queries together into a single message. To create a chained message, first create a command or query, then add a semicolon (;), and finally add more commands or queries and semicolons until you are done. If the command following a semicolon is a root node, precede it with a colon (:). Figure 2–2 illustrates a chained message consisting of several commands and queries. The chained message should end in a command or query, not a semicolon. Responses to any queries in your message are separated by semicolons.

:Config:Setup Standard;:Setup:BlockSize 200;:View1:Marker:X?;:Util2:Source?

First command Second command Second query

The response from this chained message might be:

First query

1.2;Active

Response from first query Response from second query

Figure 2-2: Example of chaining commands and queries

If a command or query has the same root and lower-level nodes as the previous command or query, you can omit these nodes. In Figure 2–3, the second command has the same root node (Marker) as the first command, so these nodes can be omitted.

:View1:Marker:X 1.5;:View1:Marker:Y -20;:View1:Marker:DeltaMarker On

Identical root and lowerĆlevel nodes

:View1:Marker:X 1.5;Y -20;DeltaMarker On

Command Syntax

Unit and SI Prefix

General Rules

If a decimal numeric argument refers to amplitude, frequency, or time, you can express it using SI units instead of the scaled explicit point input value format <NR3>. (SI units conform to the Systeme International d’Unites standard.) For example, you can use the input format 200 m or 1.0 M instead of 200.0E–3 or

1.0E+6, respectively, to specify the argument.

NOTE. You must omit the unit, such as Hz and dB. For example, 5 MHz of frequency is represented by “5M” in a command.

The SI prefixes, which must be included, are shown below. Note that either lower or upper case prefixes can be used.

SI prefix p/P n/N u/U m/M k/K m/M g/G

Corresponding power 10

* Note that the prefix m/M indicates 10-3when the decimal numeric argument denotes

amplitude or time, but 10

Here are three general rules for using the analyzer commands, queries, and parameters:

H You must use double (“ ”) quotation marks for quoted strings.

correct: “This string uses quotation marks correctly.” incorrect: ‘This string also uses quotation marks correctly.’ incorrect: “This string does not use quotation marks correctly.’

H You can use upper case, lower case, or a mixture of both cases for all

commands, queries, and parameters.

:VIEW1:MASK:RBW1M:FREQUENCYĂ25M

Constructed Mnemonics

Some header mnemonics specify one of a range of mnemonics. For example, a view mnemonic can be either View1, View2, ... or View8. You use these mnemonics in the command just as you do any other mnemonic. For example, there is a View1:Format command, and there is also a View2:Format command. In the command descriptions, this list of choices is abbreviated as View<x>.

Command Groups

General Programming Sequence

The programs for controlling the analyzer have the following steps in general:

1. Configuration: Use the Configuration command group to set the basic

operation mode and assign the Views. Also, use the Remote command subgroup (Util8) to set the communication

parameters with other device.

2. Setup: Use the Setup command group to set the hardware, such as frequency,

span, trigger, and memory.

3. Acquisition: Use the Configuration command group to start or stop the

waveform acquisition. You can load previously acquired data with the Save/Load command

subgroup (Util2).

4. Measurement and Display: Use the View command group to measure and

display the result. For example, if you have selected the Spectrogram View in the configuration, use the Spectrogram View command subgroup.

You can use the Average command subgroup (Util3) to average waveforms. Also, you can save the data to a file with the Save/Load command subgroup

(Util2). Section 4, Programming Examples shows some example programs. Powering on the analyzer initializes its settings to the factory defaults. For the

details about the factory defaults, refer to Appendix B: Factory Initialization Settings.
