Tektronix AWG70000 series arbitrary waveform generator

Tektronix AWG70000 series arbitrary waveform generator

Product Overview

Product coverage: AWG70000 series full models (such as AWG70001 single channel, AWG70002 dual channel), supporting software version 7.0 and above.

Compliance certification: Complies with EN 61010-1, UL 61010-1, CSA C22.2 No. 1010.1 safety standards to ensure compliance in industrial use.

Remote control setup: Ethernet and GPIB

1. Ethernet control (recommended)

(1) Hardware connection

Connect the Ethernet port of the instrument Rear panel to the LAN switch/PC using an RJ-45 Ethernet cable, supporting speeds of 10BASE-T (10Mbps), 100BASE-TX (100Mbps), and 1000BASE-T (1Gbps).

(2) Protocol and Configuration

Protocol type requirements for application scenarios

VXI-11 Server instrument and PC are both equipped with TekVISA standard remote control, with strong compatibility

Both the Raw Socket instrument and PC are equipped with TekVISA high-speed data transmission and low latency

DHCP is enabled by default for IP acquisition, and the IP is automatically obtained from the router. If a fixed IP is required, the laboratory's fixed network environment can be modified through Windows network settings

2. GPIB control (compatible with traditional devices)

(1) Hardware connection

Instrument Rear panel USB 2.0 HS Device port → connect to the host port of TEK-USB-488 adapter;

Connect the GPIB port of the adapter to the GPIB card/interface of the PC using a GPIB cable.

(2) Key configuration rules

Address uniqueness: Each device on the bus must be assigned a unique address (1-30), which cannot be duplicated;

Bus limitation: Up to 15 devices can be connected, with 1 device required every 2 meters (6 feet), and the total cable length should be ≤ 20 meters (65 feet);

Power requirement: At least 2/3 of the equipment should be powered on to avoid signal attenuation;

Topology: Only supports star or linear connections, and prohibits ring/parallel connections.

(3) Address modification steps

Instrument end: Go to Utilities → System → GPIB Address, set a new address (default 1);

Restart adapter: Disconnect and reconnect the TEK-USB-488 adapter to ensure the new address takes effect.

Command syntax specification: SCPI standard and execution mechanism

1. Core grammatical symbols

Example of symbol meaning

<>Defined element (required)<wfm_name>(waveform name)

Defined as<Block>::=#<NZDig><Dig>... (Block Data Definition)

`XOR (choose one) ON OFF (choose one)

{} Required group (choose one) ` {INTernal EXTernal} ` (required internal/external)

[] Optional section [:]<Header>(colon optional)

... The preceding elements can be repeated<Argument>[,<Argument>...] (multi parameter)

() Comment #<NZDig>(non-zero digits)

2. Command and Query Structure

(1) Command (modify settings/execute actions)

Format: [:]<Header>[<Space><Argument>[<Comma><Argument>...]

Example: CLOCk: SURce INTernal (set clock source to internal)

(2) Query (Get Status/Data)

Format: [:]<Header>? [<Space><Argument>[<Comma><Argument>...]]

Example: CLOCk: SURce? (Query the current clock source)

3. Parameter types and rules

Example of Parameter Type Description

Boolean 0/OFF (false), 1/ON (true) AWGControl: DLOading: ENABle 1 (enable dynamic loading)

Discrete fixed options (such as MIN/MAX) FGEN: CHANnel1: AMPCrude MAX (amplitude set to maximum)

Numerical values (NR1/NR2/NR3/NRf) NR1 (integer, such as 123), NR2 (decimal, such as 12.3), NR3 (scientific counting, such as 1.23E3), NRf (flexible format) CLOCk: SRATE 25E9 (sampling rate 25GS/s)

String needs to be enclosed in single/double quotes MMEMory: OPEN "C: waveform. wfmx" (load file)

Arbitrary Block: Binary data block in the format of #<NZDig><Dig>...<DChar>... WLILD: WAVeform: DATA "TestWfm", # 41024xxxx... (transmitting 1024 points of data)

4. Command execution mechanism

(1) Three types of commands

Example of Type Characteristics

Execute the next command OUTPut1: STATe ON only after the previous command is completed; OUTPut2: STATe ON (First turn on CH1, then turn on CH2)

During the execution of the blocking command, other commands are prohibited, which takes a long time. CALibration [: ALL] (full calibration, waiting for completion)

Overlapping commands can be executed concurrently with other commands, and it is necessary to manually ensure the completion of DIAGnostic: STARt (diagnostic startup, requires OPC)? Confirmation completed)

(2) Key Execution Rules

Abbreviation rule: Commands can be abbreviated, with the capitalized part being the abbreviation core (such as TRIGger: LEVel → TRIG: LEV);

Splicing rules: Use; Splicing multiple commands, different root nodes need to add: (such as TRIG: SUR EXT; :SOUR1:RMODe TRIG）；

Termination symbol: When sending commands, EOI (last byte assertion) should be used as the termination symbol, and the instrument response should be terminated with LF+EOI;

Clear command: * CLS clears all event registers and queues, Device Clear (DCL) resets the command reception status.
