Oscilloscopes Selection Guide: Technical Criteria & Application Standards
Oscilloscopes selection guide: technical parameters, mounting and compliance standards, and Unit comparison.
An oscilloscope is a measuring device that shows the change of an electrical signal's voltage over time as a waveform on its screen. It is used in electronic board design and repair, in drive and power supply troubleshooting, and in training laboratories to examine the amplitude, frequency and rise time of a signal. This category lists Unit's handheld and benchtop digital oscilloscopes with 1, 2 and 4 channels, bandwidths such as 50 MHz, 100 MHz and 200 MHz, and sampling rates such as 500 MS/s and 1 GS/s. Choose the bandwidth according to the highest frequency component of the signal you will examine, the sampling rate and memory depth according to the detail you want to capture, the channel count according to the number of signals to be monitored at the same time, and handheld or benchtop type according to the working environment. Bandwidth is the frequency at which the device shows a sine signal attenuated by 3 dB; for this reason, signals with fast edges such as square waves require a bandwidth considerably higher than the base frequency. An oscilloscope shows the waveform of the voltage; a multimeter, which gives the value as a single number, does not replace it. The Oscilloscopes category on Welibaba includes 14 active models from leading manufacturers such as Unit.
Key Technical Parameters for Selecting Oscilloscopes
To specify the right Oscilloscopes model for your panel or installation, verify the following parameters against your engineering schedule:
| Parameter | Typical Catalog Values | Verification Note |
|---|---|---|
| Display Size | 3, 5 inç TFT, 320 × 240, 5 | Verify against project schedule and load calculation |
| Bandwidth | 100 MHz, 150 MHz, 16MHz, 200 MHz | Verify against project schedule and load calculation |
| Gram | 0.9 kg, 1.8 kg, 2.5 kg, 3 kg | Verify against project schedule and load calculation |
| Sampling Rate | 1 GS/s, 1 GS/s (kanal başına), 1 GS/s (tek kanal), 500 MS/s (iki kanal) | Verify against project schedule and load calculation |
Installation, Compatibility, and Commissioning Checklist
- Electrical & Mechanical Matching: Confirm that rated voltage, current capacity, and mounting dimensions align with the upstream and downstream components in Measuring Instruments.
- Environmental & Enclosure Rating: Check IP protection class, housing material, and terminal capacity for dusty, humid, or high-vibration industrial environments.
- Related Product Groups: If your application calls for a different form factor or rating, compare sibling categories such as LED Bulb Test Stands, Ammeters and Voltmeters, Electrical and Electronic Testers.
