Hantek DSO-4254B 4-ch, 250MHz Bench Oscilloscope
Hantek DSO-4254B 4-ch, 250MHz Bench Oscilloscope
The Hantek DSO-4254B is a Four-channel, 250MHz bandwidth digital oscilloscope designed for professional electronic engineers.
It features a sensitive 500μV/div minimum amplitude range for low-level signals, a fast 1GSa/s sample rate, an Advanced Triggering System with high-trigger sensitivity and a low-trigger jitter.
The display features a large 7" 64K colour TFT display and dedicated individual channel controls aligned vertically to the channel inputs. The instrument can be controlled from a host PC via its USB interface, and captured data can be stored on a USB memory stick.
The scope also features a Digital Multimeter and a serial bus decoding and triggering, making it ideal for monitoring onboard I2C and SPI bus activity.
