  • Page 8 Environmental considerations This section provides information about the environmental impact of the ATS5004D. ATS5004D end-of-life handling Production of the ATS5004D required the extraction and use of natural resources. The equipment may contain substances that could be harmful to the environment or human health if improperly handled at the ATS5004D’s end of life.

  • Page 9: Introduction

    Introduction Before using the ATS5004D first read chapter about safety. Many technicians investigate electrical signals. Though the measurement may not be electrical, the physical variable is of- ten converted to an electrical signal, with a special transducer. Common transducers are accelerometers, pressure probes, current clamps and temperature probes.
  • Page 10 Figure 3.1: Single ended input Therefore the voltage that is measured with an oscilloscope with standard, single ended inputs is always measured between that specific point and ground. When the voltage is not referenced to ground, connecting a standard single ended oscilloscope input to the two points would create a short circuit between one of the points and ground, possi- bly damaging the circuit and the oscilloscope.

  • Page 11: Differential Attenuators

    Figure 3.2: Differential input A differential input is not referenced to ground, but both sides of the input are ”floating”. It is therefore possible to connect one side of the input to one point in the circuit and the other side of the input to the other point in the circuit and measure the voltage difference directly.
  • Page 12 Figure 3.4: Differential input Standard oscilloscope probes and attenuators only attenuate one side of the signal path. These are not suitable to be used with a differential input. Using these on a differential input will have a negative effect on the CMRR and will introduce measurement errors.

It will also influence the measurements and create measurement errors. do not connect the outside of the two BNC’s of the attenuator to each other as this will short circuit a part of the internal circuit and will create measurement errors do not connect the outside of the BNC’s of two or more at- tenuators that are connected to different channels of the Han- dyscope HS4 Diff...

  • Page 14: Sample Frequency

    Figure 3.6: Sampling The sine wave in figure is sampled at the dot positions. By connecting the adjacent samples, the original signal can be recon- structed from the samples. You can see the result in figure 3.7. Figure 3.7: ”connecting” the samples Sample frequency The rate at which the samples are taken is called the sampling frequency, the number of samples per second.

  • Page 15: Aliasing

    Figure 3.8: The effect of the sampling frequency The sampling frequency must be higher than 2 times the high- est frequency in the input signal. This is called the Nyquist fre- quency. Theoretically it is possible to reconstruct the input signal with more than 2 samples per period.
  • Page 16 signals with a frequency ranging from 0 to 500 Hz. This means that from the resulting frequencies in the table, we can only see the 250 Hz signal in the sampled data. This signal is called an alias of the original signal. If the sampling frequency is lower than twice the frequency of the input signal, aliasing will occur.

  • Page 17: Digitizing

    Digitizing When digitizing the samples, the voltage at each sample time is converted to a number. This is done by comparing the voltage with a number of levels. The resulting number is the number cor- responding to the level that is closest to the voltage. The number of levels is determined by the resolution, according to the following relation: LevelCount = 2 The higher the resolution, the more levels are available and...

In the setting AC, a capacitor will be placed between the input connector and the input circuit. This capacitor will block all DC components of the input signal and let all AC components pass through.

  • Page 19: Driver Installation

    Where to find the driver setup The driver setup program and measurement software can be found in the download section on TiePie engineering’s website and on the CD-ROM that came with the instrument. It is recommended to install the latest version of the software and USB driver from the website.
  • Page 20 installation of a driver on a system and also to update an existing driver. The screen shots in this description may differ from the ones displayed on your computer, depending on the Windows version. Figure 4.1: Driver install: step 1 When drivers were already installed, the install utility will re- move them before installing the new driver.
  • Page 21 Figure 4.2: Driver install: step 2 When the instrument is still connected, the driver install utility will recognize it and report this. You will be asked to continue anyway. Figure 4.3: Driver install: Instrument is still connected Clicking No will bring back the previous screen. The instru- ment should now be disconnected.
  • Page 22 Figure 4.4: Driver install: step 3 On Windows XP and newer, the installation may inform about the drivers not being ”Windows Logo Tested”. The driver is not causing any danger for your system and can be safely installed. Please ignore this warning and continue the installation. Figure 4.5: Driver install: step 4 The driver install utility now has enough information and can install the drivers.

  • Page 25: Hardware Installation

    Hardware installation Drivers have to be installed before the ATS5004D is con- nected to the computer for the first time. See chapter more information. Power the instrument The ATS5004D is powered by the USB, no external power supply is required. Only connect the ATS5004D to a bus powered USB port, otherwise it may not get enough power to operate properly.

  • Page 26: Connect The Instrument To The Computer

    Connect the instrument to the computer After the new driver has been pre-installed (see chapter 4), the ATS5004D can be connected to the computer. When the ATS5004D is connected to a USB port of the computer, Windows will report new hardware. The Found New Hardware Wizard will appear. Depending on the Windows version, the New Hardware Wizard will show a number of screens in which it will ask for information regarding the drivers of the newly found hardware.
  • Page 27 This window will only be shown in Windows XP SP2 or newer. No drivers for the ATS5004D can be found on the Windows Update Web site, so select No, not this time and click Next . Figure 5.2: Hardware install: step 2 Since the drivers are already pre-installed on the computer, Windows will be able to find them automatically.
  • Page 28 Figure 5.3: Hardware install: step 3 The New Hardware wizard will now copy the required files to their destination. Figure 5.4: Hardware install: step 4 The first part of the new driver is now installed. Click Finish to close the wizard and start installation of the second part, which follows identical steps.

  • Page 29: Plug Into A Different Usb Port

    Once the second part of the driver is installed. measurement software can be installed and the ATS5004D can be used. Plug into a different USB port When the ATS5004D is plugged into a different USB port, some Windows versions will treat the ATS5004D as different hardware and will ask to install the drivers again.
