Accurately measure your signals

With up to 200 MHz bandwidth, 4 channels, and 5 GS/s maximum sample rate, no other oscilloscope offers as much bandwidth and sample rate in a portable handheld form factor. The THS3000 Handheld Oscilloscope Series has 10,000 points record length per channel, enabling you to capture more signal information at higher sample rates to clearly see signal details. For applications where it is important to measure slow-changing signals over long time periods, the THS3000 Series offers Roll mode that extends the record length to 30,000 points of signal information.




Four isolated input channels easily handle any type of mixed signal inputs

Safely make floating and differential measurements




Isolated-channel technology is specified to 1000 VRMS maximum float voltage

Making accurate and safe measurements on power electronics, power semiconductors, and other electronics applications can be challenging when the signal reference is floating and not referenced to earth ground. When your signal ranges from low voltage to high voltage (kV) or you must use probing techniques that can potentially create ground loops, the problem is compounded.

To enable floating measurements, the THS3000 Series is architecturally different than most other oscilloscopes. All input channels are fully isolated from the main chassis and from each other. Additionally the power adapter and USB interface are fully isolated to ensure safe measurements and eliminate the risk of unintentional grounding or accidental short circuits. When configured with the proper probes you can be assured you’ll be able to make quick, safe, and accurate measurements.

Fast analysis of your device

The THS3000 Handheld Oscilloscope Series is packed with analysis tools to help you validate your device’s operation and identify issues quickly. With waveform math, you can add, subtract, or multiply any of your signals to investigate instantaneous power or look at gain. Vertical and horizontal cursors allow you to look at a specific point on your waveform for accurate measurements of voltage, current, time, or frequency. With 21 automated measurements, you can make common measurements quickly and accurately. The built-in Fast Fourier Transform (FFT) function allows you to see the frequency spectrum of your signal, revealing signal interference, crosstalk, or switching noise.

Find intermittent faults with TrendPlot™




Analyze measurements and recordings visually or using measurement cursors

Intermittent faults can be caused by timing errors, temperature changes, environmental influences, or simply broken wiring or connectors. The TrendPlot™ function helps you find those faults by plotting minimum and maximum measurement values over time. You can select up to 4 measurements and plot any combination of voltages, amps, frequency, time, and phase for any or all four inputs, all with time capture information.

Automatic capture and data logging of 100 display screens




Playback of captured data is quick and easy with the THS3000 series oscilloscopes

Capturing random or changing signals can often be difficult. The THS3000 Series greatly simplifies any type of waveform data logging by continuously capturing 100 display screens. Each screen capture can include multiple channels and math waveforms, each with its own time stamp. Data capture can also be tailored to specific events by selection of qualified trigger conditions. Playback is quick and easy with the automatic replay of all captured screens or only the screens you select.

Waveform limit testing




User-defined limit testing can easily identify random waveform anomalies

The THS3000 Series can automatically monitor your signals and output Pass or Fail results by judging whether the input waveform is within predefined boundaries. User selections can include testing one or all input channels and automatic recording of Pass or Fail data. Data can easily be reviewed using the Replay mode or stored externally to a USB memory device.

Complete solution for power measurements




Easily calculate the instantaneous power by multiplying voltage and current waveforms

For performing power measurement on motor drives, power converters/inverters, and power semiconductor devices the THS3000 Series is equipped to handle most common measurements. For basic debugging, the isolated input channels can be used with a variety of voltage and current probes. Each input channel can be configured to match the probe type and attenuation ensuring correct measurements and cursor readings. Four channels allow for easy measurements of three-phase power or simultaneous capture of digital control and power signals.

Measurements on power conversion electronics usually require probes with higher voltage ratings. Tektronix offers a passive probe with insulation systems specifically designed for making floating measurements. The standard THP0301-X can measure up to 849 Vp-p(300 Vrms). Optional P5122 probes, when coupled with the THS3000 Series, are suitable for making measurements on 1000 Vrmsdevices in Category II environments, with a maximum float voltage of up to 600 Vrmsrelative to earth ground.

Designed to make your work easier

Intuitive operation

The THS3000 Handheld Oscilloscope Series has a front-panel layout and an intuitive user interface which makes the instrument easy to use, reducing learning time and increasing efficiency. For initial setup or for situations where you’re constantly changing connection points, the THS3000 Series has a single-button Autoset and Autorange feature which can automatically set up the trigger system and adjust vertical and/or horizontal oscilloscope settings.

Easy to use

The bright color display makes it easy for you to see the signals you’re measuring. Each waveform is color coded and designed to correspond to the colors on the input probe connectors, the front-panel channel selector buttons, and the individual probes which are colored at both ends. By matching the colors during setup you’ll be assured you can easily identify your waveforms.

For setup assistance user messages are available in 11 user-selectable languages including English, French, German, Spanish, Portuguese, Italian, Japanese, Simplified and Traditional Chinese, Korean, and Russian.

Flexible data transfer
