  • Using UltraScope from RIGOL with NI Max on Windows 10

    Using UltraScope from RIGOL with NI Max on Windows 10

    Some versions of Windows 10 make it difficult to run UltraScope from UltraSigma, RIGOL’s communications platform. UltraSigma can have difficulty accessing needed files and directories.

    For RIGOL Oscilloscopes (UltraVision I and II including the DS1000Z, DS1000Z-E, DS2000A, MSO2000A, DS4000, MSO4000, MSO5000, DS7000, MSO7000, DS8000-R, and MSO8000), there is currently a workaround to access the capabilities of UltraScope without starting UltraSigma.
    Start by installing the full version of the latest NI-VISA appropriate for your Operating System. At the time of writing this was NI VISA 20.0 for Windows 10. This installs NI MAX as well.
    Then install UltraScope from the appropriate scope family page on rigolna.com.
    Connect your instrument over USB and then Open NI MAX. Select the arrow next to “Devices and Interfaces” to see the connected instruments. Click on your oscilloscope and then copy the VISA Resource Name like this:







    Now Open UltraScope by clicking on the shortcut on the desktop or in the apps directory. It will start with this screen:

    Select Search for Instruments.

    On this screen click OK:


    Now click on Manual Input VISA Address here:


    Now paste in the VISA Address from NI Max, Select the instrument from the list, and click OK:


    UltraScope will start and capture traces from your Oscilloscope:


    You can capture the scope display image directly by right clicking on UltraScope and selecting “Print Instrument Screen”:

  • Math Operations

    Math Operations

    Math Functions allow you to perform calculations on one or more signals allowing for rapid signal comparison and enabling advanced modeling of more complex waveforms.

  • Average detector

    Average detector

    The RIGOL DSA800 and DSA700 families have an RMS Average detector which is great for basic average measurements. However, the RMS Average detector differs from the Linear Average detectors associated with many EMI measurements.

    This measurement can best be approximated by combining a video bandwidth filter of 10 Hz and using a linear amplitude scale mode. This test method is considered appropriate by the FCC.

    This and a great wealth of information on EMI measurements and techniques can be found in the EMI Troubleshooting book cited above.

  • AMK Advanced Measurement Kit

    AMK Advanced Measurement Kit

    AMK-DSA800 option provides various measurement functions, including T-Power (Total Power), ACP (Adjacent Channel Power), Chan Pwr (Channel Power), OBW (Occupied Bandwidth), EBW (Emission Bandwidth), C/N Ratio, Harmo Dist (Harmonic Distortion) and TOI (Third Order Intermodulation). For advanced measurement functions, the measurement mode can be single or continuous and you can control the measurement including Restart, Pause and Resume.

    1. T-Power

    The instrument enters zero span mode and calculates the power within the time domain.  The types of powers available include Peak, Average and RMS.

    1. ACP

    Measure the Powers of the main channel and adjacent channels as well as the power difference between the main channel and each of the adjacent channels.  When this function is enabled, the span and resolution bandwidth of the analyzer are adjusted to smaller values automatically.

    1. Chan Pwr

    Measure the power and power spectral density within the specified channel bandwidth.  When this function is enabled, the span and resolution bandwidth are automatically adjusted to smaller values.

    1. OBW

    Integrate the power within the whole span and calculate the bandwidth occupied by this power according to the specified power ratio.  The OBW function also indicates the difference between center frequency of the channel under measurement and the center frequency of the analyzer.

    1. EBW

    Measure the bandwidth between two points on the signal which are X dB below the highest point within the span.

    1. C/N Ratio

    Measure the powers of the carrier and noise with the specified bandwidths as well as their power ratio.

    1. Harmo Dist

    Measure the power of each order of harmonic and THD (total harmonic distortion) of the carrier.  The highest order of harmonic available is 10 and the fundamental wave amplitude must be greater than -50 dBm, or else the measurement will be invalid.

    1. TOI

    Measure the parameters of the TOI production of two signals with the same amplitude and similar frequency.  Those parameters include the frequencies and amplitude of the Base Lower, Base Upper, 3rd Order Lower and 3rd Order Upper signal, as well as the intercepts of both the Base Lower and the Base Upper.

  • Why am I seeing the message “Intermediate Frequency Out of Range”?

    Why am I seeing the message “Intermediate Frequency Out of Range”?

    There is too much power being delivered to the instrument.

    The Spectrum Analyser is a Swept Superheterodyne design and does not have preselection filters. Therefore, the mixer is seeing all of the power (full 9kHz-1.5GHz frequency range) regardless of what you have set for the start and stop values.

    A fixed attenuator should be added  to the input before running any more tests. Perhaps 10dB to start. Then, scan quickly (100kHz RBW) from 9kHz-1.5GHz and look for peaks near 10dB or greater. These spikes are overpowering the mixer and could damage the instrument.

  • DSA800 USB file limit

    DSA800 USB file limit

    On the DSA800 series with current firmware up to version 1.18 there is a known limit on the number of files that can be shown when viewing a USB stick’s content on the instrument front panel.

    This limit is 50 files or directories. Once this number is reached additional files will not be shown in the file browser. This can cause an issue if you are saving a lot of limit, setup, or data files that you want to open later on the analyzer itself. This can also cause an issue when trying to load firmware on a full memory stick.

    To make certain all your files can be viewed or opened on the analyzer we suggest separating files into folders so that no single directory has more than 50 items in it.

  • What’s the latest firmware that can be installed on my DSA815?

    What’s the latest firmware that can be installed on my DSA815?

    DSA815/TG’s with the following levels of hardware can be updated to the latest firmware:
     
    BOOT version number: 00.01.04 and later
    Digital FPGA version number: 00.05 and later
    RF FPGA version number: 00.05 and later
    Main board version number: 00.05 and later
     
    If your DSA815 has a lower level of hardware the latest firmware level that should be installed is v1.08.

  • Setting up the DSA800 series spectrum analyzers to capture the lowest level signals

    Setting up the DSA800 series spectrum analyzers to capture the lowest level signals

    The  DSA800 series spectrum analyzers consist of the DSA815, DSA832E, DSA832 and DSA875. Each can come with or without a tracking generator.

    The lowest level signal you will be able to see captured on a spectrum analyzer will be limited by the DANL or displayed average noise level so the lower the DANL the  better.

    To obtain the lowest DANL the DSA800 series analyzers will need to be operating within these parameters and settings:

    Attenuation = 0 dB
    RBW = VBW = 100Hz
    Sample Detector
    Trace Average greater or equal to 50
    Tracking  Generator set to  off
    Normalized to  1Hz
    Operating between 20°C to 30°C
