Simplified and low-cost design with high accuracy, high stability, and dual functions

The model MFG206 synthesizer is a function generator equipped with a phase-locked loop (PLL) circuit that is capable of generating a highly accurate and stable frequency. The arbitrary function synthesizer can be used for the following applications : (1) A function synthesizer that can generate sine, triangle, or square wave in the wide bandwidth of 1mHz to 20MHz with a wide amplitude, as high as 30Vp-p at open load. (2) A 12-bit and 128K-word arbitrary waveform generator that has a sampling frequency of 10MHz maximum. The model MFG206 synthesizer is a superb function generator having high signal accuracy and stability despite its simplified and low cost design, whose superior cost effectiveness justifies its uses for many applications.


Function synthesizer section
Wide frequency range : 1mHz to 20MHz
The synthesizer can output signals that range as wide as 1mHz (0.001Hz) to 20MHz. Note that the upper limit frequency for the triangular wave is 10 MHz.

Wide amplitude : 30Vp-p
The synthesizer can output a signal that has wide amplitude, as high as 30Vp-p at open load. The maximum amplitude is 15Vp-p when it is terminated with a 50-ohm load.

Triangle wave, 30Vp-p output

@

Synthesizing method
The synthesizer generates the sine wave by means of the three pairs of PLL circuits (PLL1, PLL2, and PLL3) and frequency mixers (MIX1, MIX2, and MIX3). The triangle and square waves are generated based on the PLL circuit formed between the sine wave as a reference frequency and the triangle wave generator as a voltage control oscillator.
As stated above, all the three waveforms are output as highly stable wave signals that are phase-locked by the reference crystal oscillator.

Burst and gate functions
Burst or gated waveform can also be output in addition to the continuous waves.
(1) Burst
The synthesizer can output a given waveform having a specified cycle number (1 to 4096) starting from the predetermined phase (-90X to +90X with 1X step). The wave output begins at the rising edge of the TRIG input pulse or at the manual operation. The burst waves can be output in the frequency range of 0.100Hz to 999.9kHz.

Burst wave (phase : 45X, 4cycles)

@

(2) Gate
The wave is output at the predetermined phase (-90X to +90X with 1X step) when TRIG input reaches the high level. The wave output stops at the predetermined phase after TRIG input reaches the low level.
The gated wave can be output in the frequency range of 0.1000Hz to 999.9kHz.

Gated waveform (phase : 0X)


Sweep
The frequency can be swept up to the ratio of 1 : 100 by setting the start and stop frequencies. The sweep time can be set within the range of 0.01 to 10 seconds. It is also possible to select the sweep mode, either to the linear sweep or logarithmic sweep mode. In addition, the SWEEP SYNC output synchronized with the sweep is also available. This is a very convenient function. The four sweep ranges (200kHz to 20MHz, 10kHz to 1MHz, 1kHz to 100kHz and 100Hz to 10kHz) will be automatically selected after setting the start and stop frequencies. An error message will be displayed on the LCD unit if the two frequencies are set beyond the specified sweep frequency range.

Example : Start frequency : 20kHz  /   Stop frequency : 2MHz Error message

Sweeping waveform

@

VCF input
A frequency is output, which is proportional to the voltage applied to the VCF input. The dynamic range is approximately 1 : 100. Six sweep ranges are available (200kHz to 20MHz, 10kHz to 1MHz, 1kHz to 100kHz, 100Hz to 10kHz, 10Hz to 1kHz, and 1Hz to 100Hz).

Example : 10V 20MHz   0.1V 200kHz (In the frequency range of [200kHz to 20MHz])

@

Saving and loading of the settings
A maximum of 10 parameters can be saved in the memory. The saved data will not be erased even when the equipment power supply is turned off since it is backed up by a battery.

Applications of the function synthesizer
(1) Applications of the burst function (Driver for ultrasonic devices)
The synthesizer can be used as an optimum driver for the ultrasonic devices since it can output the high voltage signal of 30V, and a wide variety of waveforms can be created by varying the phase and cycle number. The signal can be obtained by inputting the pulses into the TRIG input.

Application of burst function (sine wave)

@

(2) Application of the sweep function (Measurement of the frequency characteristics)
Connect the FUNC output to the input terminal of a component such as the filter, amplifier, or equivalent. Then, connect the component output to CH1 of the oscilloscope and SWEEP SYNC output to CH2. The sweep range can be varied up to 100 times either in the linear or logarithmic mode.

Measurement of frequency characteristics

@

(3) Application of the VCF function (Frequency modulator)
Apply the signal and offset voltage to the VCF input. Any desired frequency modulation effect can be obtained by setting the offset voltage to the carrier frequency.

Arbitrary waveform generator

Overall construction

The arbitrary waveform generator creates and edits a given waveform using the Windows 95 (the software to generate the arbitrary waveform and RS-232C cable are included as the standard accessories). The waveform is then transmitted to the MFG206 synthesizer. Any waveform can be easily formed and edited using the Windows 95. In addition, this function can also be used for a wide variety of applications with its high-capacity and high-resolution waveform data (128K words and l2 bits per word) since its sampling frequency is as high as 10MHz maximum.
