Anritsu MG3690C Series Signal Generator Video Review

In this video, a company representative Anritsu and technical journal editor Microwaves & RF discuss the Anritsu MG3690C signal generator series. The conversation takes place at the Anritsu booth. Speaking about the exceptional capabilities of this series, the representative of the company emphasized the capabilities of these generators for the development and verification of radars, including the ability to simulate up to four separate responses with a given delay.

At the end of the video, we talk about the use of MG3690C generators for the development and tuning of modern telecommunications equipment using various types of QAM modulation. The minimum phase noise of this generator provides the level of introduced vector error EVM less than 0.1% at 10 GHz, due to which the generator practically does not introduce additional errors into the measurement results of the characteristics of the studied telecommunication equipment.

A short video review of the Anritsu MG3690C series RF signal generators.


The Anritsu MG369xC Series High Frequency Measurement Signal Generators are synthesized sinusoidal signal sources with high amplitude and frequency accuracy. Devices of this series allow you to generate both a pure sinusoidal signal of a given frequency, and with various types of modulation (AM, FM, FM and IM). It is also possible to perform wideband and narrowband stepping from 2 GHz to 67 GHz. Options 4, 5 and 22 allow you to extend the lower limit of the frequency range down to 0.1 Hz, that is, you can cover the frequency range from 0.1 Hz to 70 GHz with one device. All functions of this series of signal generators are fully controlled via front panel controls or remotely via the IEEE-488 General Purpose Bus (GPIB).

It is also possible to generate trains of two, three or four pulses with independently adjustable repetition rate and pulse width, which makes these signal generators particularly suitable for radio echo simulation. This feature is very useful in the development and tuning of radars.

Expanding the capabilities of Anritsu MG3690C generators with options

As standard, the MG3690C Series can generate a pure sine wave from 2 GHz up to the corresponding model's upper range (20 GHz, 40 GHz, 50 GHz, or 70 GHz). The minimum power of this signal is limited to -20 dBm. The maximum signal power depends on the generator model and the set frequency and is in the range from +3 dBm to +19 dBm. Also in the basic configuration there is no possibility to modulate the output signal.

To significantly expand the capabilities of the basic configuration of the generator, the developer of this series offers more than 20 different options, the installation of which significantly expands the capabilities and improves the characteristics of the device in terms of frequencies, power range, signal spectral purity, modulations, etc. The main options are listed below on this page under Options and accessories. For a complete list of extension options with a detailed description, see below on this page in the section Documentation.

Physically, most of the options are printed circuit boards or separate modules that are installed inside the generator case during its production. After assembly, each copy of the generator is factory set and calibrated on a special automated measuring stand. Therefore, before ordering a generator, it is necessary to select all the required options. This photo shows the internals of the Anritsu MG3690C series generators. Some of the boards and modules shown are installed only when the corresponding options are ordered.

An example of using the MG3690C series generator with the MG3710A vector generator

Option 7 is intended for the formation of complex digital types of modulation at high frequencies. When ordering this option, a separate high-quality mixer is installed in the MG3690C series generator, which allows any signal entering the IF input to be transferred up in frequency. This figure shows an example when an 8PSK digitally modulated signal is received from the MG3710A vector generator. This signal is applied to the IF input of the MG3694C generator and transferred to a frequency of 38 GHz. The resulting 38 GHz signal with 8PSK modulation is available at the generator's RF output, which is located on its rear panel. This feature is very useful when working with radio relay stations and other high-frequency telecom equipment.

Extending the Frequency Range of the MG3690C Series Generators to 500 GHz

The Anritsu MG3697C can generate signals up to 70 GHz. This is currently a record high. But if you need even higher frequencies, then the 2000-1694 series of laboratory frequency multipliers will allow you to generate signals up to 500 GHz. The 2000-1694 series frequency multipliers are fully supported by the MG3690C. In the generator menu you can select the multiplier model. In this case, the frequency readings on the generator screen will be automatically recalculated in accordance with the coefficient of the multiplier used.

The 2000-1694 series includes eight multiplier models, each designed for a different frequency range. For example, this photo shows the appearance of two frequency multipliers: model 2000-1694-10-R with a frequency range from 75 GHz to 110 GHz and model 2000-1694-06-R with a frequency range from 110 GHz to 170 GHz. Detailed characteristics of the 2000-1694 series, see below on this page in the section Documentation in the Anritsu MG3690C generator description file.
