  • Page 8 Environmental considerations This section provides information about the environmental impact of the Handy- scope HS6 DIFF. End-of-life handling Production of the Handyscope HS6 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 HS6 DIFF’s end of life.

  • Page 9: Introduction

    Introduction Before using the Handyscope HS6 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 11 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, possibly damaging the circuit and the oscilloscope.

  • Page 12: Safeground On Each Channel

    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 13: Differential Attenuators

    Figure 3.3: SafeGround A button on each channel toolbar in the software allows to control the SafeGround state between differential and single ended When SafeGround is enabled for a channel, the input is switched to single ended and the ground current of that input is real time monitored. When the ground current becomes too high (<500 mA), the ground connection is immediately (<100 ns) opened, protecting the input against short circuits to ground.
  • Page 14 Figure 3.5: Differential attenuator For a differential input, both sides of the input need to be attenuated. Figure 3.6: 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 15: Differential Test Lead

    • do not connect other cables to the attenuator than the ones that are sup- plied with the instrument • do not touch the metal parts of the BNC’s when the attenuator is connected to the circuit under test, they can carry a dangerous voltage. It will also in- fluence the measurements and create measurement errors.

  • Page 16: Sampling Rate

    Figure 3.8: Sampling The sine wave in figure is sampled at the dot positions. By connecting the adjacent samples, the original signal can be reconstructed from the samples. You can see the result in figure 3.9. Figure 3.9: ”connecting” the samples Sampling rate The rate at which the samples are taken is called the sampling rate, the number of samples per second.

  • Page 17: Aliasing

    Figure 3.10: The effect of the sampling rate The sampling rate must be higher than 2 times the highest frequency in the input signal. This is called the Nyquist frequency. Theoretically it is possible to recon- struct the input signal with more than 2 samples per period. In practice, 10 to 20 samples per period are recommended to be able to examine the signal thor- oughly.

  • Page 18: Digitizing

    Figure 3.11: Aliasing In figure 3.11, the green input signal (top) is a triangular signal with a frequency of 1.25 kHz. The signal is sampled with a rate of 1 kSa/s. The corresponding sam- pling interval is 1/1000Hz = 1ms. The positions at which the signal is sampled are depicted with the blue dots.

  • Page 19: Signal Coupling

    Figure 3.12: The effect of the resolution The Handyscope HS6 DIFF measures at e.g. 14 bit resolution (2 =16384 levels). The smallest detectable voltage step depends on the input range. This voltage can be calculated as: V oltageStep = F ullInputRange/LevelCount For example, the 200 mV range ranges from -200 mV to +200 mV, therefore the full range is 400 mV.
  • Page 20 When using an oscilloscope probe in 1:1 the setting, the bandwidth of the probe is only 6 MHz. The full bandwidth of the probe is only obtained in the 1:10 setting The x10 attenuation is achieved by means of an attenuation network. This atten- uation network has to be adjusted to the oscilloscope input circuitry, to guaran- tee frequency independency.

  • Page 23: 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 24 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 HS6 DIFF is disconnected from the computer prior to starting the driver install utility.

  • Page 27: Hardware Installation

    Hardware installation Drivers have to be installed before the Handyscope HS6 DIFF is connected to the computer for the first time. See chapter for more information. Power the instrument The Handyscope HS6 DIFF is powered by the USB, no external power supply is required.

  • Page 28: Plug Into A Different Usb Port

    Handyscope HS6 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. Operating conditions The Handyscope HS6 DIFF is ready for use as soon as the software is started. How- ever, to achieve rated accuracy, allow the instrument to settle for 20 minutes.

  • Page 29: Combining Instruments

    Combining instruments When more channels are required than one instrument can offer, multiple instru- ments can be combined into a larger combined instrument. To combine two or more instruments, the instruments need to be connected to each other using special cables. The CMI (Combine Multiple Instruments) interface that is available by default on the Handyscope HS6 DIFF provides an easy way to couple multiple oscilloscopes to one combined oscilloscope.
  • Page 30 Figure 6.2: CMI connectors Connecting is done by daisy chaining the CMI connectors of the instruments prior to starting the software, using special coupling cables (order number TP-C50H). The software will detect how the instruments are connected to each other and will automatically terminate the connection bus.

  • Page 37: Specifications

    Specifications To achieve rated accuracy, allow the instrument to settle for 20 minutes. When subjected to extreme temperatures, allow additional time for internal tempera- tures to stabilize. Because of temperature compensated calibration, the Handy- scope HS6 DIFF will settle within specified accuracy regardless of the surrounding temperature.
