BK 2540B Series Digital Storage Oscilloscopes

×
  • 1 uHz to 20 MHz sine output
  • 1 uHz to 20 MHz square output,1 mHz to 10 MHz pulse output
  • 30 built-in arbitrary waveforms
  • Save up to 10 user-defined arbitrary waveforms to internal storage
  • AM, FM, FSK, PSK, and PWM modulation
  • Frequency sweep and burst mode
 
The 2540B, 2542B, 2540B-GEN, and 2542B-GEN dual channel 60 MHz and 100 MHz digital storage oscilloscopes deliver performance and value, all in one portable solution. Maximize productivity using extensive features such as digital filtering, waveform recorder, pass/fail limit testing, and automatic measurements. These oscilloscopes offer powerful tools in a small affordable package with deep waveform memory up to 2.4 Mpts plus LAN and USB PC interface. The 2540B-GEN and 2542B-GEN models add a built-in function/arbitrary waveform generator (AWG).

Easily capture, save, and analyze measurement results with Comsoft PC software. All scope parameters can be controlled via a PC without the need for programming or communicate with the DSO via the built-in LAN interface using a web browser.

Additionally, these oscilloscopes can be integrated with AWGs using B&K Precision's waveform editing software, WaveXpress. WaveXpress allows users to easily modify waveforms downloaded from the scope and can also be used for analysis of deep memory acquisitions.

Educators will appreciate the ability to disable the Auto Set button that would automatically setup the scope to display a signal, circumventing the need to know how to set up scope parameters. This is key for teaching waveform measurement fundamentals as if it was an analog oscilloscope. These oscilloscopes are ideal for applications in design and debugging, service and repair, and education.

The Tools You Need

Web-Enabled
The built-in LAN interface allows you to easily capture screenshots at a user-configurable refresh rate with a web browser. A GUI simulating the front panel provides full DSO control. This feature can be useful in an education setting.

PC Connectivity
Comsoft software provides seamless integration between the oscilloscope and PC. Capture and transfer waveforms, screen images, setups, and measurement results to a Windows PC via the LAN and USB device port on the back of the instrument. A USB host port on the front allows for quick and easy screen saving to a USB flash drive.

Deep Memory
Beneficial for applications such as I2C serial data streams, deep memory lets you capture waveforms in high resolution while maintaining a high sample rate over a longer period of time. Up to 2.4 Mpts of memory can be captured in as fast as 5 seconds* using binary transfer through the LAN or USB interface.

Powerful Measurement Functions
Display and measure the input signal’s frequency spectrum. Select one of the 5 FFT windows: Rectangular, Hanning, Hamming, Blackman, and Flattop. Use cursors to measure the spectral component’s magnitude and frequency.

Multi-Language Interface
Operate the oscilloscope in a language you understand best with the built-in multi-language interface. Choose from English, Simplified Chinese, Traditional Chinese, Korean, Japanese, French, German, Russian, Spanish, Portuguese, and Polish.

Waveform Recorder
Monitor and analyze long-term signal behavior by recording data continuously over an extensive period of time and playing it back for post acquisition analysis. Data is recorded in a sequence of up to 1000 frames.

Pass/Fail Testing
Generate user-defined pass/fail limits to quickly identify go/no go test results.

Digital Filtering
Filter out unwanted signal components such as various types of noise with built-in digital filters. Choose from Low-Pass, High-Pass, Band-Pass, and Band-Stop filters.

BK 2542B-GEN / 'SCOPE REVIEW

Pros:
* Has VERY handy Arbitry Signal Generater; it's a versatile gemeral purpose instrument
* Other features and performance similar to TEK
* Good quality
* Good value (mine came with free accesories)

Cons:
* Needs higher resoluton display (I miss the clean analog 'scope displays; my digital TEK 100 MHz display is no better)
* Some of the controls and soft keys are a bit esoteric (but with patience and practice, they work)
