  • Page 5: Welcome

    Welcome Wireless measuring has now become a reality with the WiFiScope WS6. If a large distance needs to be bridged between the measuring instrument and the PC, the WiFiScope WS6 is the solution for this. Fast measurements and high speed data acquisition are now possible wherever the WiFiScope WS6 is located in the world.

  • Page 7: Safety

    Use a good isolation transformer or a differential probe when measuring at the line voltage or at grounded power supplies! A short-circuit current will flow if the ground of the WiFiScope WS6 is con- nected to a positive voltage. This short-circuit current can damage both the WiFiScope WS6 and the computer.

  • Page 9: Declaration Of Conformity

    8601 WL Sneek The Netherlands EC Declaration of conformity We declare, on our own responsibility, that the product WiFiScope WS6-1000(XM/E/S) WiFiScope WS6-500(XM/S) WiFiScope WS6-200(XM/S) for which this declaration is valid, is in compliance with EC directive 2011/65/EU (the RoHS directive)
  • Page 10 In order to avoid release of such substances into the environment and to reduce the use of natural resources, recycle the WiFiScope WS6 in an appropriate system that will ensure that most of the materials are reused or recycled appropriately.

    It can be connected to the computer via USB, wired ethernet and WiFi. When used via WiFi, the WiFiScope WS6 can be connected to an existing WiFi network or can act as access point to create its own WiFi network.
  • Page 12 ≤ 5 MSa/s when connected to USB 2.0 ≤ 3.125 MSa/s when connected to USB 2.0, measuring 3 or 4 channels These maximum streaming rates are only achieved when using the WiFiScope WS6 via its USB interface. When used as wired network instrument, maximum stream- ing rates may be lower, depending on network speed and load.

  • Page 13: Sampling

    Resistance can be shown in meter displays and can also be plotted versus time in a graph, creating an Ohm scope. With the accompanying software the WiFiScope WS6 can be used as an oscillo- scope, a spectrum analyzer, a true RMS voltmeter or a transient recorder. All in- struments measure by sampling the input signals, digitizing the values, process them, save them and display them.

  • Page 14: Sampling Rate

    Figure 4.2: ”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 4.3, with a higher sampling rate, the original signal can be reconstructed much better from the measured samples.

  • Page 16: Digitizing

    16384 = 24.41 µV. Signal coupling The WiFiScope WS6 has two different settings for the signal coupling: AC and DC. In the setting DC, the signal is directly coupled to the input circuit. All signal com- ponents available in the input signal will arrive at the input circuit and will be mea- sured.

  • Page 17: Probe Compensation

    When measuring DC signals, make sure to set the signal coupling of the input to DC. Probe compensation The WiFiScope WS6 is shipped with a probe for each input channel. These are 1x/10x selectable passive probes. This means that the input signal is passed through directly or 10 times attenuated.

    • via the USB interface When using the WiFiScope WS6 via its battery, no external power is required. The power consumption of the WiFiScope WS6 depends heavily on the settings of the instrument, when using higher sampling rates the instrument uses more power.

  • Page 24: Charging The Battery

    When storing the WiFiScope WS6 for a long time, it is recommended to first charge the battery to approximately 70 %. Do not store the WiFiScope WS6 for a long time with an empty battery or 100 % fully charged battery, as this may reduce battery capacity.

  • Page 25: Instrument Operation Mode

    To enable it again, a short press on the Power/Mode button is required. When the WiFiScope WS6 is not connected to external power or USB and is not used for two days (network interface disabled), the WiFiScope WS6 switches to ”Shipping mode”, where the network interface is consuming no power at all.

    USB. When used as network instrument (LAN or WiFi), combining is not possible. The CMI (Combine Multiple Instruments) interface that is available by default on the WiFiScope WS6 provides an easy way to couple multiple oscilloscopes to one combined oscilloscope. Figure 7.1: CMI diagram The CMI interface supports automatic recognition of the instrument.
  • Page 32 A 20 channel instrument is easily made by connecting five WiFiScope WS6s to each other. When combining one or more WiFiScope WS6 s with Handyscope HS5 s and/or WiFiScope WS5s, the daisy chained CMI bus must begin or end with a WiFiScope WS6.
