Tektronix Digital Oscilloscope
- TBS1000 series digital storage oscilloscope for electronics applications such as product design and debugging, repair and servicing, and electrical engineering education
- Maximum real-time sample rate of 2GS/s and record length of 2.5kpts per channel for acquiring detailed waveforms
- Vertical sensitivity to 2mV per division for capturing low-level signals
The next product we’ve reviewed is the Tektronix TBS1102B Digital Storage oscilloscope, a device packed with excellent features that make it our premium choice.
As soon as the device captures a signal, its advanced math will accelerate analysis. You are able to determine rise-time or frequency through the 16 automated measurements available. Also, the device helps you isolate the signals you are interested in.
Another useful feature is its Time Limit function that helps you to identify any odd issues within the signal. Due to this self-debugging process, the Tektronix oscilloscope is perfect for many electronic applications such as product design, debugging, or repair and servicing.
Its intuitive interface makes it an excellent choice for apprentice electricians willing to get more diagnostics. This interface also includes auto-ranging, auto-setup, and dedicated per-channel controls.
This oscilloscope is also famous for its PC connectivity that allows you to pull waveform data and screen images on your computer’s desktop via the rear-panel USB port. Moreover, you can print out images to a PictBridge compatible printer.
Lightweight and compact, the Tektronix TBS1102B oscilloscope comes with a 5-year warranty. Although the price is a little higher, its advanced features make it the best choice for an apprentice electrician.CHECK PRICE
- Advanced triggers such as pulse and line-selectable video
- Multi-Language User Interface
- Zoom function included
- Built-in waveform limit
- Memory per channel is too low
- Difficulty to input change settings
Hantek Digital Oscilloscope
If you want a good and inexpensive oscilloscope, we recommend you the Hantek DSO4102C digital oscilloscope. This is the perfect device for hobbyists and electricians on a budget. If you want both a multimeter and an oscilloscope, this is your pick.
Hantek oscilloscope is a lightweight and compact model with well-balanced parameters in the channel mode. When used in Dual Channel mode, this device reaches up to 35 MHz speed thus being one of the fastest tools in its range.
Another awesome feature is its memory depth – the single band channel holds 32k memory while the dual-band channel detains 16k memory. You will be able to keep multiple data sources with no issue.
The Hantek Digital Oscilloscope is perfect if you’re on a budget. For instance, it is comfortable, but it doesn’t have a rotating knob to help select menu parameters and control the signal trigger. However, users start to get used to its device’s push-button control, which ensures better mobility once it’s in use.
With 6 hours of battery power autonomy, this oscilloscope is perfect for daily use. And it also comes with two channels with a 2GS sample rate through each of them. You will get accurate readings in no time.
As a minor drawback, the Hantek device requires software if you want to use the DSO Analyzer through a computer. This way you will be able to save, analyze, and share your accurate readings.
Overall, the Hantek DSO4102C oscilloscope is a great addition to your gear, especially if you are an apprentice. If you are still uncertain, you should know that the package includes all the required accessories. We say it worth checking out this oscilloscope.CHECK PRICE
- Very affordable
- 2.5k record length for all channels
- Includes a Zoom function
- Great battery autonomy
- Software errors
- Lack of support response
Siglent Digital Oscilloscope
- 100Mhz, 4 channels, 1Gsa/use, 1Mpts fft
- Standard decoder: iic, spi, uart/Rs232, can, lin
- 16 digital channels (mso) (four channel series only, option)
The last product we’ve reviewed for you is the Siglent SDS1104X-E, an oscilloscope that comes with 4 channels and 100 MHz bandwidth.
If you are an advanced user and you need a device capable to perform different math operations, this is the best oscilloscope you can buy. It is capable to perform mathematical operations such as signal multiplication, division, subtraction, and addition.
Siglent device includes multiple trigger mode options for signals such as SPI, UART/RS232, or CAN. It uses Phosphor Technology which eases signal accuracy. Moreover, the signals are displayed on its 7″ LCD screen and there are also web browser and WiFi controls.
This oscilloscope is also power-efficient as it uses 25W, lower than the average 50W. You will be the proud owner of an efficient device that helps to decrease energy bills.
What we did not like is the fact that it tends to have issues capturing frequencies under 199 kHz. However, it still has a capture rate of 40,000 waveforms a second with its Zoom Measurement/Gate features. Plus, its interface is a little too complex for beginners although they learn how to use it very quickly.
To summarize, the Siglent digital oscilloscope is one of the best devices available, its features making it the ideal machine for hobbyists and electrician apprentices.CHECK PRICE
