Introduction
The MS-250 Mixed Signal Oscilloscope Option is a complete system that
adds digital acquisition and triggering capabilities to a Teledyne LeCroy
oscilloscope.
Once properly connected to the oscilloscope and the device under test, you
will be able to use the oscilloscope user interface for the following:
•Digital Logic Control: Set the logic threshold and hysteresis for each
lead bank, choosing from standard logic families or entering a
custom setting.
•Digital Group Management: Combine individual digital lines into bus
groups to be managed together. Give lines descriptive logical
names, regardless of the physical lead number.
•Digital Analysis: Display digital signals as single line traces or
collapsed bus traces. Many of the same tools available for
analyzing analog signals may be applied to digital signals.
•Digital and Combined Triggering: Choose to set an acquisition
trigger on a digital signal pattern or a combination of conditions
using both analog and digital signals.
The MS-250 is ideally suited for embedded controller testing where there is
a proliferation of analog signals coincident with digital signals. You can
easily debug signals using standard oscilloscope tools such as cursors,
measurement parameters, and zooming. Oscilloscopes compatible with the
MS-250 feature large, bright color displays to facilitate signal viewing, plus
all the connectivity and documentation capabilities needed to quickly record
and distribute information.
Technical Overview
The MS-250 is an external device that digitally samples waveform data at
up to 1 GS/s (for 250 MHz digital signals). Unlike a logic analyzer, it
operates only in a Timing Analysis mode, so it requires 4x oversampling to
determine the correct digital edge position, but it does not require the user
to input a clock.
The USB 2.0 connection downloads the trigger setup from the oscilloscope
and uploads digital data from to the oscilloscope.

While in SINGLE, NORMAL, or AUTO trigger mode, the MS-250 repeatedly
samples each digital channel’s voltage level. If the voltage is above the
threshold, the MS-250 stores a 1 in internal memory; if it is below threshold,
a 0 is stored.
Figure 1. MS-250 sampling.
The MS-250 keeps sampling its inputs until the oscilloscope is put into
STOP trigger mode. Data is stored in a 50 Mpt internal memory that is
periodically transferred to the oscilloscope via the USB 2.0 cable. If the
oscilloscope is triggering in SINGLE or NORMAL trigger mode, data is
acquired and transferred only when the trigger condition is satisfied. The
captured data is displayed on the oscilloscope in a time-aligned fashion.
In any trigger mode (AUTO, NORMAL, SINGLE), pressing STOP trigger
cancels the acquisition, which leaves the previously acquired data
unchanged.
