Tektronix THS3000 handheld oscilloscope

The THS3000 handheld oscilloscope series provide up to 200 MHz bandwidth and 5 GS/s sample rate. The oscilloscopes weigh 2.18 kg, offer seven hours of battery life and four isolated channels.

Models are available with either 100 MHz and 2.5 GS/s maximum sampling rate or 200 MHZ and 5 GS/s sample rate performance. With a 10,000 point record length per each of four channels, users can capture extensive signal information at high sample rates to clearly see signal details.

Each channel on the oscilloscope is isolated from the chassis ground and from each other. Further, the external USB inputs for data storage, instrument setups and PC communication are also isolated. This enables the user to safely make floating measurements for voltages up to 300 VRMS CAT III when using the included 10X probes or 1000 VRMS CAT II with optional probes. The instrument has 600 VRMS CAT III rated inputs (BNC to earth ground) for safe high voltage measurements.

Offering 21 automated measurements, the oscilloscopes enable users to make many common measurements quickly and accurately. A built-in fast fourier transform (FFT) function provides insight into to the frequency spectrum of a signal, revealing signal interference, crosstalk or switching noise

Handheld oscilloscopes are often used to perform power measurements on motor drives, power converters/inverters and power semiconductor devices. Each of the four input channels can be configured to match the probe type and attenuation, ensuring correct measurements and cursor readings.
