25 MHz Digital Storage Oscilloscope
Description
Oscilloscopes are used to observe the change of an electrical signal over time. 25 MHz digital storage oscilloscope stores and analyses the signal digitally rather than using analogue techniques. It is widely used in science, pharmacy, engineering and telecommunication industries.
Advantages
1. 25 MHz digital storage oscilloscope can build waveforms after the signal is digitized thus the instrument has the advantages of memorizing and storing the observed signals.
2. It has very high bandwidth and the maximum is up to 25 MHz.
3. The highest sampling rate of digital storage oscilloscope is up to 1GS/s thus it’s not prone to produce signal aliasing.
4. 25 MHz digital storage oscilloscope has more trigger modes such as pre-trigger, logic trigger and pulse width trigger.
5. Digital phosphor oscilloscope (DPO) can be connected to the computer as well as print, archive and analyze documents.
6. DSO has powerful waveform processing ability and is able to measure frequency, rise time and pulse width automatically.

Cautions
1. Avoid hot and humid places and frequent start-up and shutdown.
2. When operator observes the bright spot in the screen and makes adjustments, its brightness should be moderate.
Maintenance
1. Choose oscilloscope with corresponding bandwidth according to actual requirement. Generally the frequency bandwidth is 2-5 times of test signal.
2. Choose power system with stable voltage as it helps to reduce interference and stabilize the test signal.
3. 25 MHz digital storage oscilloscope should avoid moisture, dropping, dust and interference from the around strong magnetic field.
- 40 MHz Digital Storage Oscilloscope40 MHz digital storage oscilloscope stores and analyses the signal digitally rather than using analogue techniques. It is now the most common type of oscilloscope in use because of the advanced trigger, storage, display and measurement features. Like mixed signal oscilloscope (MSO), it is also a kind of portable oscilloscope. This digital oscilloscope (also includes digital phosphor...
