  • Page 8 Environmental considerations This section provides information about the environmental impact of the Handy- scope HS4 DIFF. End-of-life handling Production of the Handyscope HS4 DIFF 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 Handyscope HS4 DIFF’s end of life.

  • Page 9: Introduction

    Introduction Before using the Handyscope HS4 DIFF first read chapter about safety. Many technicians investigate electrical signals. Though the measurement may not be electrical, the physical variable is often converted to an electrical signal, with a special transducer. Common transducers are accelerometers, pressure probes, current clamps and temperature probes.

  • Page 10: Differential Input

    Differential input Most oscilloscopes are equipped with standard, single ended inputs, which are referenced to ground. This means that one side of the input is always connected to ground and the other side to the point of interest in the circuit under test. 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.

  • 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 attenuator matches with differential input Standard oscilloscope probes and attenuators only attenuate one side of the sig- nal 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.

  • Page 13: Differential Test Lead

    • do not apply excessive mechanical force to the attenuator in any direction (e.g. pulling the cable, using the attenuator as handle to carry the Handy- scope HS4 DIFF, etc.) 3.1.2 Differential test lead The Handyscope HS4 DIFF comes with a special differential test lead. This test lead is specially designed to ensure a good CMRR.

  • Page 14: Sampling Rate

    Figure 3.7: ”connecting” the samples Sampling rate The rate at which the samples are taken is called the sampling rate, the number of samples per second. A higher sampling rate corresponds to a shorter interval between the samples. As is visible in figure 3.8, with a higher sampling rate, the original signal can be reconstructed much better from the measured samples.

  • Page 16: 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 re- sulting number is the number corresponding to the level that is closest to the voltage.

  • Page 19: Driver Installation

    The driver setup program and measurement software can be found in the down- load section on TiePie engineering’s website. It is recommended to install the latest version of the software and USB driver from the website. This will guarantee the latest features are included.
  • Page 20 Figure 4.1: Driver install: step 1 When drivers were already installed, the install utility will remove them before in- stalling the new driver. To remove the old driver successfully, it is essential that the Handyscope HS4 DIFF is disconnected from the computer prior to starting the driver install utility.

  • Page 23: Hardware Installation

    When the Handyscope HS4 DIFF is plugged into a different USB port, some Win- dows versions will treat the Handyscope HS4 DIFF as different hardware and will install the drivers again for that port. This is controlled by Microsoft Windows and is not caused by TiePie engineering. Hardware installation...

    Rear panel Figure 7.1: Rear panel Power The Handyscope HS4 DIFF is powered through the USB. If the USB cannot deliver enough power, it is possible to power the instrument externally. The Handyscope HS4 DIFF has two external power inputs located at the rear of the instrument: the dedicated power input and a pin of the extension connector.

    Figure 7.3: USB power cable One end of this cable can be connected to a second USB port on the computer, the other end can be plugged in the external power input at the rear of the instrument. The power for the instrument will be taken from two USB ports of the computer. The outside of the external power connector is connected to +5 V.
