1. Work with yo H500 instrument. If the network has DHCP enabled, the instrument will automatically obtain an IP address when powered on and connected to the network. If your network does not support DHCP, or you need a ﬁxed IP address for your instrument, have your system administrator provide you with an address.

2. Connect a standard Ethernet cable from a network connector to the Ethernet port on the top of the instrument. You can do this before or after powering on the in

3. Power on the instrument if it is not already powered on.

4. On the instrument, tap Start > Settings > Network and Dial-up Connections

to open the Network Connections dialog box. The instrument network interface is listed as ENDS4ISA1.

5. Double-tap the ENDS4ISA1 icon to open the CSA8900 Settings dialog box:

If your instrument is using DHCP to obtain an IP address, and the Obtain

an IP address via DHCP button is set, you do not need any further network conﬁguration. Close the dialog box and continue to the next

If the instrument has already been assigned a ﬁxed IP address, the address

If you are assigning or changing the instrument ﬁxed IP address, tap the

6. Close the Network Connections dialog box. You can now use the network interface to control the H500 or SA2500 application using the network-accessed programmable interface.

Getting Started

Using the Prog

rammable Interface

The H500 and SA2500 programmable interface consists of simple text commands. These are modeled after the Standard Commands for Programmable Instruments (SCPI) synta requests the spectrum analyzer's center frequency. The instrument uses raw TCP sockets to receive commands and send replies. To send a command to the H500 or SA2500, make a connection on TCP port 34835 and send the text of the command, followed by a newline (ASCII 10). The instrument will reply on the same TCP port, and will add a newline to the end of its response.

Appendix C lists C++ source code that uses the Win32 Winsock library to interface to the H500 or SA2500. Included is a custom library module with routine responses, and determining details when error conditions occur. Also included is a test wrapper that uses the custom library module to perform basic instrument operations. Appendix C also lists MATLAB code that uses the MATLAB Instrument Control Toolbox plug-in to interface to the H500 or SA2500. The MATLAB example opens the interface, sends a simple query command, and then

Command Syntax

SCPI Commands

and Queries

SCPI is a standard created by a consortium that provides guidelines for remote programming of instruments. These guidelines provide a consistent programming environment deﬁned programming messages, instrument responses, and data format across all SCPI instruments, regardless of manufacturer. The instrument uses a command language based on the SCPI standard.

The SCPI language is based on a hierarchical or tree structure as shown in the following ﬁgure that represents a subsystem. The top level of the tree is the root node; it is followed by one or more lower-level nodes.

Figure 2-1: Example of SCPI subsystem hierarchy tree

You can create commands and queries from these subsystem hierarchy trees. Commands specify actions for the instrument to perform. Queries return

rement data and information about parameter settings.

measu

for instrument control and data transfer. This environment uses

Creating Commands

Creating Queries

SCPI commands are created by stringing together the nodes of a subsystem hierarchy and se parating each node by a colon.

In the ﬁgure above, TRIGger is the root node and EVENt, EXTernal, INPut, INTe rnal, and SOURce are lower-level nodes. To create a SCPI command, start

th the root node TRIGger and move down the tree structure adding nodes

wi until you reach the end of a branch. Most commands and some queries have parameters; you must include a value for these parameters. If you specify a parameter value that is out of range, the parameter will be set to a default value. The command descriptions list the valid values for all parameters.

For example, :TRIGger:EVENt:INTernal BOTH is a valid SCPI command created from the hierarchy tree. (See Figure 2-1.)

To create a query, start at the root node of a tree structure, move down to the end of a branch, and add a que stion mark. TRIGger:EVENt:SOURce? is an example of a valid SCPI query using the hierarchy tree in the ﬁgure. (See Figure 2-1.)

Query Responses

Parameter Types

The query cause

s the instrument to return information about its status or settings. When a query is sent to the instrument, only the values are returned. When the returned value is a mnemonic, it is noted in abbreviated format, as shown in the following table.

A few queries also initiate an operation action before returning information. For example, the *CAL? query runs a calibration.

Every parameter in the command and query descriptions is of a speciﬁed type. The parameters are enclosed in brackets, such as <value>. The parameter type is listed after the parameter and is enclosed in parentheses, for example, (boolean). Some parameter types are deﬁned speciﬁcally for the H500 and SA2500 instruments command set and some are deﬁned by A NSI/IEEE 488.2-1987 as shown in the following table.

The single chained message should end in a command or q are separated by semicolons.

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 the following ﬁgure, the second command has the same root node (TRIGger:EVENt) as the ﬁrst command, so

MMEMory:SPECtrum:LOAD:TRACe<x> {TRACe1 | TRACe2 | TRACe3 | TRACe4 | TRACe5},<file_name>

TRACe1 speciﬁes to load Trace 1 waveform data from the ﬁle.

TRACe2 speciﬁes to load Trace 2 waveform data from the ﬁle.

TRACe3 speciﬁes to load Trace 3 waveform data from the ﬁle.

TRACe4 speciﬁes to load Trace 4 waveform data from the ﬁle.

TRACe5 speciﬁes to load Trace 5 waveform data from the ﬁle.

<file_name>::=<string> speciﬁes the measurement results ﬁle from which to

load the trace data. When the string does not include a path component, the ﬁle is loaded from the current measurement results directory. When a path is speciﬁed, the current measurement results directory is set to that path.

You must enter a ﬁle extension as part of the ﬁle name. See

MMEMory:LOAD:RESults for a table of valid measurement results ﬁle
