Comparison of Keysight InfiniiVision 1000 X-Series, Tektronix TBS1000B-EDU, and Rigol DS1000Z Series Oscilloscopes
When selecting an oscilloscope for R&D, laboratory, education, electronics repair, or electronic system development, Keysight, Tektronix, and Rigol are among the brands commonly considered by engineers.
Although oscilloscopes from these manufacturers may offer similar bandwidth and sampling rates, their practical capabilities can differ significantly.
In addition to key specifications such as bandwidth, number of channels, and sampling rate, users should also consider memory depth, waveform update rate, triggering capabilities, serial bus decoding, and integrated analysis tools. These factors directly affect the ability to detect glitches, noise, and intermittent faults during debugging.

Each series has its own strengths. The Rigol DS1000Z offers four analog channels and deep memory, while the Tektronix TBS1000B-EDU provides bandwidth options of up to 200 MHz. The Keysight InfiniiVision 1000 X-Series, meanwhile, places greater emphasis on acquisition speed, debugging capabilities, and integrated measurement tools.
Bandwidth and Sample Rate
All three series offer models suitable for general electronic testing.
Within the 50–100 MHz range, the Keysight DSOX1102A and DSOX1102G provide sampling rates of up to 2 GSa/s, which is useful when engineers need to examine signal edges, fast switching signals, or short-duration events in greater detail.
Waveform Update Rate
The Keysight InfiniiVision 1000 X-Series can achieve a waveform update rate of 50,000 waveforms per second, while the Rigol DS1000Z specifies a waveform capture rate of up to 30,000 waveforms per second.
A higher waveform update rate allows the oscilloscope to perform more acquisitions within a given period, increasing the probability of capturing short or infrequent events such as glitches, runt pulses, transient noise, or intermittent faults.
For practical troubleshooting and debugging, fast waveform acquisition can therefore be an important consideration rather than focusing solely on bandwidth or memory depth.
Memory Depth
In terms of memory capacity, the Rigol DS1000Z offers up to 24 Mpts, providing a significant advantage when long signal capture is required while maintaining a large number of sample points.
The Keysight EDUX1002A and EDUX1002G provide 100 kpts of memory, while the DSOX1102A and DSOX1102G offer up to 1 Mpts. The Tektronix TBS1000B-EDU Series has a record length of 2.5 kpoints.
Deep memory is particularly useful when engineers need to capture signals over longer periods without significantly reducing the number of acquired samples.
Serial Triggering and Protocol Decoding
Modern embedded systems commonly combine analog signals with communication buses such as I²C, SPI, UART, CAN, and LIN. Therefore, serial triggering and protocol decoding have become important criteria when selecting an oscilloscope.
The Rigol DS1000Z supports serial triggering and analysis for protocols including I²C, RS-232, and SPI. Keysight InfiniiVision 1000 X-Series models can support I²C, SPI, UART/RS-232, CAN, and LIN depending on the model and installed options.
This allows engineers to correlate analog waveform behavior with digital communication activity, helping identify relationships between a communication packet and an abnormal signal event.
Such capabilities are particularly valuable in embedded systems, IoT devices, sensor systems, automotive electronics, and electronics R&D.
Integrated Measurement Functions
The Rigol DS1074Z-S Plus and DS1104Z-S Plus integrate a two-channel 25 MHz signal generator, helping expand their functionality in laboratory environments.
The Keysight EDUX1002G and DSOX1102G integrate a 20 MHz WaveGen function generator and support frequency response analysis with Bode plots.
Depending on the configuration, the Keysight InfiniiVision 1000 X-Series can also provide functions such as a digital voltmeter, frequency counter, and serial protocol analysis, enabling a single instrument to handle multiple bench tasks—from signal generation and waveform observation to voltage and frequency measurement and circuit response analysis.
Which Oscilloscope Should You Choose: Keysight, Tektronix, or Rigol?
There is no single oscilloscope model that is ideal for every application.
For applications where four analog channels and deep memory are the main priorities, models such as the Rigol DS1054Z, DS1074Z Plus, and DS1104Z Plus may be worth considering.
For applications requiring bandwidth of 150–200 MHz, the Tektronix TBS1152B-EDU and TBS1202B-EDU extend beyond the bandwidth range of the Keysight 1000 X-Series.
For applications focused on electronic circuit and embedded system debugging, capturing intermittent faults, serial bus analysis, and using multiple measurement tools within a single instrument, the Keysight InfiniiVision 1000 X-Series provides a well-integrated combination of capabilities.
| Main Requirement | Models/Series to Consider |
|---|---|
| Basic oscilloscope education, 50 MHz | Keysight EDUX1002A |
| Education + waveform generator/Bode Plot | Keysight EDUX1002G |
| R&D/debugging, 70–100 MHz, 2 GSa/s, segmented memory | Keysight DSOX1102A |
| R&D/debugging + WaveGen + Bode Plot | Keysight DSOX1102G |
| Priority on four analog channels and deep memory | Rigol DS1054Z / DS1074Z Plus / DS1104Z Plus |
| Four channels with integrated signal generation | Rigol DS1074Z-S Plus / DS1104Z-S Plus |
| 150–200 MHz bandwidth within the TBS1000B-EDU Series | Tektronix TBS1152B-EDU / TBS1202B-EDU |
The strength of the Keysight InfiniiVision 1000 X-Series therefore lies not in having the deepest memory or the highest number of analog channels, but in its fast acquisition performance, hardware-based processing architecture, and tightly integrated debugging and measurement tools.
Users can choose from a 50 MHz oscilloscope for educational applications to a 100 MHz configuration for R&D, while retaining key characteristics of the InfiniiVision platform, including high waveform update rates and an integrated measurement environment.
