Sample Program

In addition to the measurement control application that is attached to each product,
we provide a sample program so that measurement control can be performed even in customer's program.
You can download zip file from the link below.

MODEL Visual C++ Visual C# Linux LabVIEW REFERENCE
APN504(X) Operating Environment #1

USB-MCA4 Operating Environment #2

*We may change without prior notice.
*For other models please contact us by e-mail (
or telephone (+81-29-350-8011)

Sample Program Overview

Operation screen

If you execute the above sample program after basic setting such as histogram mode for our product,
It will be measured for 3 seconds.
The measured histogram data is saved as a readout CSV (comma-separated text) format file.

During measurement, input rate (cps) and throughput rate (cps) are displayed on the screen.
If you are using LabVIEW, a histogram is also displayed.

If you use an arbitrary waveform generator, you can check the operation by inputting the simulation signal created by the customer to our product.

Examples of simulated signals


Operating Environment

Operating Environment #1 (Communication interface uses LAN)
Connect the PC and our products with a LAN cable.
Since our product IP address is "" (default),
set the IP address of the PC's network adapter with the others. (Example, "")
Subnet mask is set at ""
Please execute "ping" from the command prompt after setting and confirm that it is normal.

Operating Environment #2
(Communication interface uses USB
Connect the PC and our products with the supplied USB cable. The driver of our product shall be installed in advance.

Development environment

We confirmed the operation in the following development environment.

Visual C ++
Visual C ++ in Microsoft Visual Studio Professional 2017

CentOS 6.7 64bit
gcc (GCC) 4.4.7 2012 0313 (Red Hat 4.4.7-16)

National Instruments LabVIEW 2014
* Please contact us if you would like to use a version prior to LabVIEW 2014.
It includes FTDI D2XX Drivers and some sample programs.


Simulated signals

If the preamplifier output signal from the detector can not be used,
a simple operation check can be performed by using the following simulation signal.

APU101 and APU504

Example of setting of Arbitrary Waveform Generator:

Ramp, Frequency:1kHz
Amplitude:100mVp-p(Hi level:100mV)
Offset:50mV(Low level:0mV)


Example of setting of Arbitrary Waveform Generator:

Square, Frequency:1kHz
Amplitude:1Vp-p(Hi level:1V)
Offset:500mV(Low level:0mV)
