Preface Default Model This manual documents the TDS 400A, TDS 510A, TDS 500C, TDS 600B, & TDS 700C Digitizing Oscilloscopes. Take special note of the following conventions: Some TDS models have two auxiliary channels called AUX 1 and AUX 2, instead of CH 3 and CH 4. Some references to these channels default to CH 3 and CH 4. The TDS 684B display screen appears as the default screen wherever a display screen is illustrated in this manual. Model References This manual documents the TDS 400A,

Getting Started TDS Example Programs Figure 1–4: The Disk That Accompanies This Manual Setting Up Remote Communications Even the best instrument control program will not do much if the instrument is not connected to the controller. The digitizing oscilloscope has a 24-pin GPIB connector on its rear panel, as shown in Figure 1–5. This connector has a D-type shell and conforms to IEEE Std 488.1–1987. Attach an IEEE Std 488.1–1987 GPIB cable (available from Tektronix as part number 012–0991–00) to

Getting Started If needed, you can stack GPIB connectors as shown in Figure 1–6. Figure 1–6: How to Stack GPIB Connectors GPIB Requirements Observe these rules when you use your digitizing oscilloscope with a GPIB network: Assign a unique device address to each device on the bus. No two devices can share the same device address. Do not connect more than 15 devices to any one bus. Connect one device for every 2 meters (6 feet) of cable used. Do not use more than 20 meters (65 feet) of cab

Command Syntax You can control the digitizing oscilloscope through the GPIB interface using commands and queries. This section describes the syntax these commands and queries use. It also describes the conventions the digitizing oscilloscope uses to process them. The next section, entitled Command Groups, lists the commands and queries themselves. You transmit commands to the digitizing oscilloscope using the enhanced American Standard Code for Information Interchange (ASCII) character encoding.

Command Syntax A command message is a command or query name followed by any information the digitizing oscilloscope needs to execute the command or query. Command messages may contain five element types, defined in Table 2–2 and shown in the example in Figure 2–1. Table 2–2: Command Message Elements Symbol Meaning
The basic command name. If the header ends with a question mark, the command is a query. The header may begin with a colon (:) character. If the command is concatenated with

Command Syntax A command header consists of one or more mnemonics arranged in a hierarchi- cal or tree structure. The first mnemonic is the base or root of the tree and each subsequent mnemonic is a level or branch off the previous one. Commands at a higher level in the tree may affect those at a lower level. The leading colon (:) always returns you to the base of the command tree. Queries Queries have the structure: ' ' & '!*# $) %## '!*# $) You can

Command Syntax Clearing the TDS Family Oscilloscope You can clear the Output Queue and reset the digitizing oscilloscope to accept a new command or query by using the Device Clear (DCL) GPIB command. Command Entry The following rules apply: You can enter commands in upper or lower case. You can precede any command with white space characters. White space characters include any combination of the ASCII control characters 00 through 09 and 0B through 20 hexadecimal (0 through 9 and 11 through
