Simple operation and high stability, the benefit of digital function generator

eK-FGJ is a function generator designed for realizing smaller and more user-friendly units. The output value from the function generator can be converted and set based on our bipolar power supplies. Accordingly, the eK-FGJ features an accurate and intuitive setting without calculating the gain value.
We implemented the operability improvement by simple operation on the 3.5-inch LCD screen. As you know, the function generator usually creates a stable waveform with high accuracy.

Features

  • Designed for directly setting the output from bipolar power supplies produced by Matsusada.
  • High accuracy and stability features for signal creation
  • Intuitive operation and setting on LCD screen in a single unit
  • Programming operation with control software
  • Easy operating exclusive control software as standard equipment

Functions

Matsusada as a leading power supply manufacturer introduced direct OUTPUT display

connect eK-FGJ to bipolar power supply, DOS6.5

* The picture shows an application example with DOS60-5.

If a different output is used instead of DC, 0 V and 0 A will be displayed since the unit is dedicated to displaying DC output in DOS series

Output value from the function generator can be converted and set based on our bipolar power supplies.
Accordingly, eK-FGJ features the accurate and intuitive setting without calculating with the gain value.

The series offers the synchronous waveform output in two power supplies

connect eK-FGJ to two bipolar power supply with load

It is possible to apply the opposite synchronous waveform output by positive or negative toward motors or dielectric materials.

the opposite synchronous waveform

In the series, the synchronous output is available where the two waveforms follow the same patterns in terns of the respective cycle and sweeping start point. Besides, the phase shift is also available where one phase is shifted differing from the other.

Synchronous Output

It is designed to control the two waveforms by making them the same in terms of the cycles and the sweeping start point.

Phase Shift

The output timing is arranged by moving the phase of your choice.

Software

Easy operating exclusive control software as standard equipment

Sequence Programming Screen

Channel 1 (Ch1) and channel 2 (Ch2) can each output signals independently. The output waveform can also be selected as an arbitrary waveform created with dedicated waveform editing software. (Only one arbitrary waveform can be selected at a time for both Ch1 and Ch2.)

Arbitrary Waveform Generation

Positive and negative outputs are available respectively. You can easily generate various waveforms by adding, subtracting, and multiplying operations.

* Concerning the configuration data used for the output, the reproduction may not always coincide with the actual output waveforms.

The series offers the composition consisting of a sine wave and an amplitude which have different patterns and readily provides the waveform generation.

Arbitrary Waveform Generation in control software

The composition is also available by setting the specified range.

Options

Optical Interface Board Option

In selecting this option, the USB board is not included as a standard specification.

  • -LGob: Optical interface board + optical cable 2 meters
  • -LGob (Fc5): Optical interface board + optical cable 5 meters
  • -LGob (Fc10): Optical interface board + optical cable 10 meters
  • -LGob (Fc20): Optical interface board + optical cable 20 meters
  • -LGob (Fc40): Optical interface board + optical cable 40 meters

Isolation control is performed by optical communication. As complete isolation is performed by means of optical fiber, this enables the prevention of erroneous operation comprising transient phenomena caused by surges, inductive lightning, external noise, etc. (can be produced with the control software).
On the other hand, regarding the communication in this option, before the programming operation is performed or the arbitrary waveform is outputted, it may take several seconds for the power supply to output following the signal output. If you plan to use the unit for such applications, it is not recommended to use this option.

Select the optional optical interface board (-LGob) when using this function generator under the following conditions.

  • Noisy environment including factories (Example: Motors or coils are used near power supplies and loads).
  • Using with high voltage floating (more than 250 V).
  • Installation distance of 2 meters or more between the function generator and a controller such as a computer, laptop, or Programmable Logic Controller (PLC).
