The 2540C Digital Storage and Mixed Signal
Oscilloscope (MSO) Series 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 con-
figuration, each model offers a maximum 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 wfms/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.

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.
The tools you need
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.
Automatic Waveform Math and Measurement
Hardware Pass/Fail and Masking
Perform up to 40,000 pass/fail decisions a second. Easy to generate masking
templates help capture anomalies even with complicated waveforms.
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.
PC Connectivity
All traditional digital oscilloscope features come standard in the 2540C Series: Cursors, 50 Ω input coupling, reference signals, persist, rolling, noise
rejection and deskew.

The tools you need
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 kΩ input impedance, the probe
protects the integrity of your signal. The probe is included with MSO
models.
Buy now, upgrade later
Install the MSO and decode licenses at any time or try before you buy with the 30 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. To purchase a license key, please fill out the license request form or visit the 2540C
Series accessories page.
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.
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.
