Oscilloscopes
Oscilloscopes, also called Digital Storage Oscilloscopes (DSOs) or Mixed Signal Oscilloscopes (MSOs), are a common type of test instrument used to capture, analyze, and troubleshoot electrical or real world physical signals. Oscilloscopes observe the change of electrical signals over time, continuously graphed on a display as voltage or amplitude vs. time. During observation, oscilloscopes can analyze waveforms parametrically (i.e. frequency, RMS, peak-to-peak amplitude, rise time, etc.) Non-electrical signals, especially mechatronic signals such as vibration, strain, temperature, or current can be converted to voltages and displayed.
Yokogawa oscilloscopes deliver a range of bandwidths, up to eight channel plus sixteen logic input oscilloscopes, unparalleled suites of triggers and signal analysis, and a unique ability to save multiple triggered-events to "History" memory.
10+1 Reasons to Choose a Yokogawa Oscilloscope
Application Note
Oscilloscopes capture signals continuously and display them graphically as voltage or amplitude vs. time. Oscilloscopes can analyze waveforms parametrically in terms of frequency, root mean square (rms) amplitude, peak-to-peak amplitude, rise time, and others. Mechatronic variables such as strain, temperature, and vibration or electrical variables such as current can be converted to voltage for display.
This application note discusses the top ten reasons, plus one, to select a Yokogawa oscilloscope.
Read the App Note
A mixed signal oscilloscope is an instrument enabling the simultaneous, time correlated observations and analysis of analog with digital (logic) signals, to establish causal relationships between the various areas of a device's electronics. They are purpose-built tools for troubleshooting electrical anomalies, measuring parametric values, and monitoring cause and effect relationships between signals.
A ScopeCorder is an instrument combining a mixed signal oscilloscope and portable data acquisition recorder into a modular platform designed to capture both high-speed transients and low-speed trends. Yokogawa’s ScopeCorder product family provides flexible and high-performance multi-channel test instruments by combining a variety of signal conditioning input modules, onboard calculations, and deep data acquisition storage into an off-the-shelf data acquisition solution.
View, export, analyze, and manage your data using Yokogawa's oscilloscope application software.
An oscilloscope is only as good as its probes. Our range includes high voltage, differential, active, low capacitance, and passive types, with ranges to 7kV and frequency bandwidths to 5 GHz.
Current probes allow you to measure DC or AC current. Yokogawa's selection of current probes allow measurements ranges up to 500 ARMS and bandwidths up to 100MHz.
Logic probes allow you to capture signals using the logic portion of a mixed signal instrument. Yokogawa offers low and high voltage, isolated and non-isolated logic probes.
Oscilloscopes accessories include probe stands, cables, cases, various adaptors and more.
The IS8000 software platform is an integrated solution that accelerates engineering workflow. It is a revolutionary software that tightly integrates the timing, control, and data collection from multiple instruments, creating a comprehensive measurement suite that delivers confidence, efficiency, and unity.

In terms of display resolution, the 720210 and 701250 modules (12-bit) are equivalent to a 4 digit DMM. The 701262 module (16-bit) is equivalent to a 5 digit DMM. However, in terms of DC accuracy, the 720210 and 701250 ...
FAQ
Overview:
If you discover that your waveform data/trace or some channels have disappeared from the DL850/DL850V or Xviewer when you re-load the WDF data file, this is normal behaviour due to an incomplete acquisition.
For ...
Overview:
No, it is not possible to use the WDF File Access API in LabView to read *.WDF files.
Although LabVIEW can use and access DLLs, there is a special function in the WDF File Access API called WdfGetSacleWave64, which ...
Overview:
The formula for calculating the file size for a Binary type (with *.WDF extension) is: File Size = 805kB + (DataLength*ChannelCount*HistoryCount*2) where 805kB is the ...
Overview:
This method will not work as the signal waveform would be very distorted. The coax acts as a heavy shunt-capacitance at the 'output' jack of the passive probe circuit. As a result, this excessive shunt-capacitance ...
Overview:
Unfortunately it is not possible to convert a .WVF file to a .WDF file. A .WVF file saved by a DL750 can only be loaded in Xviewer or a DL750.
Xviewer is capable of loading both .WVF and .WDF file formats.
Overview:
No, if you send commands simultaneously from another communications interface, that has not been selected on the DL850/DL850V, the instrument will not execute the commands properly.
Overview:
If the files saved on the DL850 do not appear on the PC, please disconnect and reconnect the USB connection from the DL850 to the PC.This behavior is normal for Windows based operating systems including Windows XP, ...
Overview:
The measured output response time of the 701260 Analog Voltage Input Module, when observing RMS is:
Rising (0 to 90% of 10 div): 100ms
Falling (100 to 10% of 10 div): 250ms
An attached JPEG displays the results of ...
Overview:
For the 701280 Frequency Input Module with a 4th order IIR 6Hz lowpass filter, a 60Hz sine wave (FM modulated with a square wave) was measured with deviations of ± 3Hz. Please download and view the attached image for ...
Overview:
The attached file contains an Excel spreadsheet with an API that will query data from the DL850 via USB, to obtain and display the Time/Div setting. To use the Excel API, follow these procedures:
Download and extract ...
Overview:
Xviewer can be used to calculate various power analysis measurements such as power factor, real power, reactive power, and apparent power. Two sample waveforms are available in the attached zip file, and should be used ...
Overview:
The Delay Measurement value is a Fixed-Point Number.The Delay Measurement feature on the DL850 comes in two modes, Time and Degree. The output of the Delay Measurement feature is a time-based value and not an amplitude ...
Overview:
The DL850 is capable of linearizing an input signal using the Polynomial Feature in the /G3 Realtime Math option. The polynomial feature performs a fourth order polynomial calculation on the selected source waveform. To ...
Overview:
To set the DL850 in Roll Mode, turn the Time/Div knob until it is set to 100msec/Div or longer. If the Time/Div is set to 1Hr/Div or longer, waveform scrolling can be difficult to observe in real-time. This is due ...
Overview:
Please make sure you have the latest version of Xviewer installed.
Overview:
The DL850 G3 Power Measurement option can be used to calculate the power of a Sinusoid-Current Burst. Please download and view image for a screenshot demonstration of the DL850 G3 Power Function.The firmware version of ...
Overview:
It is not necessary to perform deskew on a DL850 when using a current probe. The DL850 does have enough resolution to perform deskew and will not be able to find the time offset.
Typically the deskew value ranges from ...
Overview:
For the DL850 G3 Frequency Function, you will need to set the hysterisis of the edges that are used to detect the periods. This will increase the tolerance for noise and improve measurement reliability.To configure ...
Overview:
The DL850 can save measured waveform data to a file in Binary, ASCII, or Floating Point format. You can use the FILE Waveform Save Menu or the SAVE MENU menu to set how files are saved.To save using the SAVE MENU ...
Overview:
Unfortunately there is no way to read these warning messages on the DL750. In addition, there is no other command available to determine if there was "No Matching Record" found in History for a particular ZONE ...
