Digital Function Generator
Fast waveform output operation suited for even complex programming patterns
- Frequency range:
0.01Hz to 1MHz - Maximum amplitude:
20Vp-p (@1kΩ = RL)
7.5Vp-p (@50Ω = RL) - Easy handling
- Simple setting
Simple operation and high stability, the benefit of digital function generator
The eK-FGJ is a compact, user-friendly function generator designed for seamless integration with Matsusada Precision bipolar power supplies. It allows you to directly set the power supply's output in volts or amps, eliminating the need for manual gain calculations. This ensures accurate, intuitive control and accelerates your testing workflow.
We implemented the operability improvement by simple operation on 3.5-inch LCD screen. This digital function generator creates highly accurate and stable waveforms.
Features
- Designed for directly setting the output from bipolar power supplies produced by Matsusada Precision.
- 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
Model
| Model | Frequency range | Number of channels | Maximum amplitude | Offset | Output impedance |
|---|---|---|---|---|---|
| eK-FGJ | 0.01 Hz to 1 MHz | 2 | 20 Vp-p (@1 k Ω = RL), 7.5 Vp-p (@50 Ω = RL) |
+ / -10 V (no load) | 50 Ω |
Functions
Direct Control of Bipolar Power Supplies
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 an accurate and intuitive setting without calculating with the gain value.
The Series Offers The Synchronous Waveform Output in Two Power Supplies
It is possible to apply the opposite synchronous waveform output by positive or negative toward motors or dielectric materials.
The series provides synchronized 2-channel outputs. Both channels can share the same waveform, cycle, and sweep start point. Additionally, a precise phase shift can be applied between the two channels.
It is designed to control the two waveforms by making them the same in terms of the cycles and the sweeping start point.
The output timing is arranged by moving the phase of your choice.

Software
Intuitive Control Software Included
Sequence Screen
The series features the independent sequence outputs with Ch1 and Ch2. Also, during the sequence operation, you can use the waveform made by a dedicated editor.
(As for the waveform of your choice, select one waveform that is commonly used in Ch1 and Ch2.)
Optional Waveform Generation
Arbitrary Waveform Generation: Easily create complex waveforms by combining two base waves (e.g., sine, square) using mathematical functions (add, subtract, multiply).
The composition is also available by setting the specified range.
They can be added, subtracted, and multiplied.
Positive and negative outputs are available respectively. Wide varieties of waveforms are available by generating according to the composition methods. * Concerning the configuration data used for the output, the reproduction may not always coincide with the actual output waveforms
Options
- Optical Interface Port Option
-
Isolation control is performed by optical communication. The optical interface option provides complete electrical isolation via a fiber optic cable. This prevents measurement errors and malfunctions caused by surges, induced lightning, and other external noise. (can be produced with the control software). On the other hand, regarding the communication in this option, before the sequence 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.
- -LGob: Optical interface port + optical cable 2 meters
- -LGob (Fc5): Optical interface port + optical cable 5 meters
- -LGob (Fc10): Optical interface port + optical cable 10 meters
- -LGob (Fc20): Optical interface port + optical cable 20 meters
- -LGob (Fc40): Optical interface port + optical cable 40 meters
Select the optional optical interface port (-LGob) when using this DC power supply under the following conditions.
- Noisy environments such as factories (example: when motors or coils are used near loads or power sources).
- If this power supply and your controller (PC or PLC) cannot be installed within 2 meters.
- When there is a possibility of arcing or output short-circuit.
When this option is selected, a standard USB port will not be installed.
How to Order
When ordering, add Option No. in the following order to Model No.
