2542C BK Precision Digital Oscilloscope

New
$1,099.00

The 2542C is a 100 MHz, 2 Channel digital oscilloscope from BK Precision. Digital oscilloscopes make use of binary numbers that correspond to samples of the electronic equipment’s voltage. This is in contrast to analog oscilloscopes, which use continually varying voltages. Digital oscilloscopes use an analog-to-digital converter (ADC) to convert the voltages it measures into digital information

The 2542C Digital Storage Oscilloscope delivers advanced features and debug capabilities for a wide range of applications at an entry-level price point. With up to 200 MHz bandwidth in a 2-channel configuration, each model offers a sample rate of 1 GSa/s, and a maximum memory depth of 14 Mpts. In addition, these oscilloscopes provide an 8” color display with 256 levels of color grading combined with a high waveform update rate up to 60,000 wfrms/sec, which allows the instruments to capture infrequent glitches with excellent signal fidelity. The logic analyzer and decode software provides 16 additional digital channels and serial bus decoding for I²C, SPI, UART/RS232, CAN, and LIN protocols.

Maximize productivity using extensive features such as digital filtering, waveform recording, pass/fail limit testing, and automatic measurements. The built-in 25 MHz function/arbitrary waveform generator (AWG) comes standard with all models and provides stimulus output of 4 arbitrary waveforms, sine, square, ramp, pulse, DC, noise, cardiac, Gaussian pulse, and exponential rise/fall waveforms to the device under test.

The 2540C Series oscilloscopes are ideal for applications in design, education, service, and repair. This instrument offers a comprehensive set of tools to capture signal anomalies, decode serial bus protocols, and help speed up debug and analysis. The MSO and decoding functionalities are available for upgrade in the field with the purchase of a license key.

All traditional digital oscilloscope features come standard in the 2540C Series: Cursors, 50 Ω input coupling, reference signals, persist, rolling, noise rejection and deskew.

Waveform History and Recording

Quickly scroll through millions of points with History Mode’s playback functionality to find difficult to capture events. Eliminate unnecessary idle signals and dead-time by selectivity capturing up to 80,000 segments.

Function and Arbitrary Waveform Generator

A powerful 25 MHz function/arbitrary waveform generator comes standard in the 2540C Series. Use complimentary software to generate waveforms and load up to 4 arbitrary waveforms into the instrument. Built-in functions are sine, square, ramp, pulse, DC, noise, cardiac, Gaussian pulse, and exponential rise/fall.

Automatic Waveform Math and Measurement

Display 36 automated measurements that include voltage, time, and statistics. Arithmetic and FFT functions can be performed on analog channels and two reference signals.

Color Grading

With 256 levels of color grading, the most common occurrences are represented in red and the least common are represented in purple. Easily spot outliers as they will persist for a user specified time.

Hardware Pass/Fail and Masking

Perform up to 60,000 pass/fail decisions a second. Easy to generate masking templates help capture anomalies even with complicated waveforms.

PC connectivity

PC software is provided (free download at www.bkprecision.com) for seamless integration between the oscilloscope and PC. Capture and transfer waveforms, screen images, setups and measurement results to a Windows PC via the USB device port on the back of the instrument. A USB host port on the front allows for quick and easy screen saving.

MSO license - LA2540C

The 16 integrated digital channels are displayed along-side analog channels allowing users to view up to 18 time-correlated channels with shared triggering and acquisition on one screen. The LA2540C license enables the 16 digital channels of the 2540C Series and is included with MSO models.

16 channel logic probe - LP2540C

The 16-channel color-coded logic probe consists of two eight-channel pods. To make contact with the DUT, the probe connects directly to square pins or clips to test points using the included grabbers. With an input capacitance of only 8 pF and 100 k Ω input impedance, the probe protects the integrity of your signal. The probe is included with MSO models.

Decode license - DC2540C

Select up to 2 serial bus protocols I2C, SPI, UART/RS232, CAN, and LIN and decode concurrently from analog and MSO channels. Decode information in real-time and display in binary, decimal, hex, or ASCII.

Buy now, upgrade later

Install the MSO and decode licenses at any time or try before you buy with the 30-day trial license on each model. Any DSO model in the 2540C Series can be upgraded to an MSO. Installation is quick and easily done within the oscilloscope menu.
