Tektronix AWG70000B Arbitrary Waveform Generator Series up to 20 GHz

SHORT DESCRIPTION

RF Arbitrary Waveform Generator Series Tektronix AWG70000B came in February 2019 to replace the similar Tektronix AWG70000A series. The AWG70000B series generators are designed for direct shaping (without the use of frequency transfer) of complex radio, wireless and satellite communications, radar pulses, serial telecommunication protocols, and other similar applications.

The series consists of two models: single-channel AWG70001B with DAC sampling rates from 1.5 kSa/s to 50 GS/s and dual-channel AWG70002B with DAC sampling rates from 1.5 kSa/s to 25 GS/s. At the heart of all models in the AWG70000B series is a proprietary, high-quality 10-bit vertical resolution DAC that generates very clean, spurious-free signals in the GHz range up to 80dB relative to carrier amplitude.

Tektronix AWG70000B generators contain the Windows 10 operating system and powerful software that allows you to create a large number of standard signals. And with the help of additional software modules (RADAR, OFDM, Environment, High Speed Serial, Optical, etc.) you can create any signals with an arbitrary change in their parameters: radar, communication, simulating interference and reflections from real objects, etc. You can download a full description of all the characteristics of the Tektronix AWG70000B series generators below on this page in the section Documentation.

DETAILED DESCRIPTION

With the Tektronix AWG70000B Series generator, you can generate any signal shape. Even the standard software that comes with the instrument allows you to create a variety of waveforms. And with ten additional software modules (RADAR, OFDM, Environment, High Speed Serial, Optical, and more), you can fully automate the creation of the desired waveforms for specific applications.

This screenshot shows the main user interface window of the Tektronix AWG70000B Generator Software (no additional software modules). Field 1 tabs allow you to switch between different modes of the generator, when installing additional software modules in field 1, menus for managing these modules will be added. Button 2 starts or stops the generation of the output signal. Button 3 allows you to quickly turn off all analog channels and all marker channels. Buttons 4 are used to switch the generator between the modes of generating standard signals and generating an arbitrary signal (in the screenshot, the generator is in the mode of generating standard signals). Buttons 7 are designed to select the signal path inside the generator, as well as to bind the corresponding marker outputs to the signal.

In addition to software specifically designed for the AWG70000B series, you can use any third-party math programs: MATLAB, Excel, and others. Another way to create the necessary signals is to "play" with the help of the AWG70000B series generators of real signals or their fragments that were recorded using oscilloscopes (for example, a series DPO70000) or real-time spectrum analyzers (for example, series RSA5000B).

RF Generic software module for creating modulated signals

The Tektronix AWG70000B RF generators, equipped with an optional RF Generic software module, allow you to create signals with various types of digital modulation on one or more carrier frequencies.

As an example, this screenshot shows the interface of the RF Generic software module. Pay attention to the IQ Impairments, Interference Addition, Distortion and MultiPath tabs, with which you can add various distortions and disturbances inherent in real signals to the generated signal.

Radar software module for creating radar signals

The Tektronix AWG70000B series high frequency generators equipped with the Radar software module are an excellent solution for creating complex pulses in radar systems. This software module is capable of generating all major types of radar pulses: LFM, Barker Codes, Polyphase Codes, Step FM, Nonlinear FM, etc. It also has many configurable settings that allow you to modify standard radar signals to obtain new shapes with specified parameters.

The combination of the Tektronix AWG70000B and the Radar software module enables Staggered PRI (Staggered PRI) radar pulse trains to simultaneously improve distance accuracy and speed accuracy.

In addition, the Radar software module allows you to generate signals with frequency jumps, pulse trains with varying amplitude and solve many other practical problems, including the implementation of the most innovative ideas. The interface of the Radar software module is shown in this screenshot.

Environment software module for simulating a real transmission environment

Any radio signal passing through the air is exposed to a large number of distorting factors: commercial radio signals, re-reflections from the terrain, intentional countermeasures (electronic warfare equipment) and other types of influences and interference. The task of the radio signal receiver is to steadily highlight the useful component against the background of distorting influences.

The Environment software module is specifically designed to comprehensively test the stability of the receiver in the presence of various types of interference. Using the Environment module, it is possible to add commercial digital radio communications signals (Bluetooth, DVB-T, P25, CDMA, GSM, WiFi, W-CDMA, LTE, WiMAX, etc.) to the generated signal, as well as radar signals, tone signals, radio signals with analog modulation, noise, etc.

This screenshot shows the interface of the Environment program module. In this example, three interfering signals are defined: pulse, WiFi, and GSM. Each signal is individually configurable, including turn-on and turn-off times, power, center frequency, modulation parameters, and more.

AWG70001B AC option for signal amplitude expansion

In a standard configuration, the maximum output amplitude of the Tektronix AWG70000B series generators can be up to 1V (peak-to-peak) for differential output and 500mV (peak-to-peak) for single-ended output, which equates to about 0 dBm power into a 50 Ω termination.

The AWG70001B AC option, which can be installed on the AWG70001B single channel generator, adds an additional AC coupled output (SMA(f) connector) on the front panel with extended amplitude range (-90dBm to +20dBm). Such a significant expansion of the amplitude occurs due to the presence of additional filters, amplifiers and attenuators inside the generator. In this case, the signal can pass through one of four paths, each of which has its own frequency range and its own output power range. The block diagram of the AWG70001B AC option is shown in this figure.

Tektronix AWG70000B Arbitrary Waveform Generator Design

The appearance of the front panel of the Tektronix AWG70001B and Tektronix AWG70002B generators is shown in this photo. Single channel model AWG70001B is located on top. In the central part of the front panel, three high-frequency connectors of the SMA (f) type are visible. Two of them are the output of an oscillator that can also work as a differential signal source. The rightmost connector (labeled AC) appears when ordering the generator with option AWG70001B AC (duplicate AC coupled output with extended output range).

The lower of the two generators is the Tektronix AWG70002B dual channel model. The layout of its front panel is similar to a single-channel generator. The difference is that in the two-channel model, you cannot install an additional redundant AC-coupled output. On the front panel of the two-channel model there are four SMA(f) connectors - two for each output of the generator, which allows you to form either a normal signal or a differential signal on each channel.

All the necessary additional connectors are located on the rear panel of the generators: input and output of the reference clock frequency of 10 MHz, external trigger inputs (Trigger Inputs) and additional outputs (four in a single-channel model and eight in a two-channel one). There are also communication interfaces for communication with a personal computer and the control input of the AWG70000B STRID (Streaming ID) option.

Optional accessories for Tektronix AWG70000B generators are listed in this figure.

The following is a list of optional software modules that greatly enhance the capabilities of the Tektronix AWG70000B generators in their respective application areas. These software modules can be installed either in the generator itself (because it contains Windows 10) or in the SourceXpress personal computer program. The license of each software module is of two types: node-locked (NL) and floating (FL). The NL license costs less, but ties the module to a specific generator or computer. The FL license is more expensive, but allows transfer from one device to another.
