MS-500 Mixed Signal Oscilloscope Option
6 ISSUED: June, 2009 MS-500-OM-E Rev C
INTRODUCTION
Overview
The MS-500 Mixed Signal Oscilloscope Option is a powerful solution for the challenge of
measuring multiple, mixed signals in a single oscilloscope. An enhancement tool to the LeCroy
WaveRunner Xi Series and WaveSurfer Xs Series oscilloscopes, the MS-500 extends their
testing range by adding 18 or 36 digital channels for display or triggering.
The MS-500 is ideally suited for embedded controller testing where there is a proliferation of
analog signals (comparators, voltage sources, sensor/actuator signals, etc.) coincident with digital
signals (address or data lines, control signals, or peripheral serial data signals). Users can easily
debug signals using standard oscilloscope tools such as cursors, measurement parameters, and
zooming.
Both oscilloscopes usable with the MS-500 feature large, bright color displays to facilitate signal
viewing, plus all the connectivity and documentation capabilities needed to quickly record and
distribute information.
This MS-500 manual assumes that you have a basic understanding of discrete electronics, logic
analyzers, and LeCroy oscilloscopes, specifically the LeCroy oscilloscope that the MS-500
system will be used with. When practical or necessary there are details on specific oscilloscope
features included in this manual.
The MS-500 and MS-500-36 are identical except the MS-500-36 standard configuration is for 36
channels. The MS-500-36 can be operated in 36 or 18 channel mode for higher performance.
The MS-500 is configured as an 18 channel instrument and can be upgraded with an additional
lead set to support 36 channels.
In this manual the MS-500 and MS-500-36 are referred to solely as MS-500.
Warranty
The MS-500 is warranted for normal use and operation, within specifications, for a period of one
year from shipment. LeCroy will either repair or, at our option, replace any product returned to
one of our authorized service centers within this period. However, in order to do this we must first
examine the product and find that the defect is due to workmanship or materials and not due to
misuse, neglect, accident, or abnormal conditions or operation.
LeCroy shall not be responsible for any defect, damage, or failure caused by any of the following:
a) attempted repairs or installations by personnel other than LeCroy representatives, or b)
improper connection to incompatible equipment, or c) for any damage or malfunction caused by
the use of non-LeCroy supplies.
Spare and replacement parts, and repairs, all have a 90-day warranty.
The oscilloscope’s firmware has been thoroughly tested and is presumed to be functional. This
includes MS-500 specific firmware. Nevertheless, it is supplied without warranty of any kind
covering detailed performance. Products not made by LeCroy are covered solely by the warranty
of the original equipment manufacturer.
MS-500-OM-E Rev C ISSUED: June, 2009 7
Returning a Product for Service or Repair
If you suspect that you have a problem with the MS-500 you should first contact your local
LeCroy service center so they can ascertain whether the component is defective.
If you need to return a LeCroy product, provide model identification by providing the model name
and serial number, describe the defect or failure, and give us your name and telephone number.
For factory returns, use a Return Authorization Number (RAN), which you can get from customer
service. Write the number clearly on the outside of the shipping carton. Return products requiring
only maintenance to your local customer service center. Within the warranty period,
transportation charges to the service center are your responsibility.
Products under warranty are then returned to you with transport prepaid by LeCroy. Outside the
warranty period, you provide us with a purchase order number before the work can be done. You
are also billed for parts and labor related to the repair work and shipping. It is highly
recommended to prepay return shipments and use air freight.
It is highly recommended to prepay return shipments and use air freight. LeCroy cannot accept
COD (Cash On Delivery) or Collect Return shipments.
Technical Support
You can get assistance with installation and operation from your customer service center. Visit
the LeCroy Web site at http://www.lecroy.com for the center nearest you.
Staying Up-to-Date
Your MS-500 hardware does not need periodic calibration.
LeCroy offers state-of-the-art performance by continually refining and improving the instrument’s
capabilities and operation. We frequently update both firmware and software during service, free
of charge during warranty. Therefore, MS-500 specific software may be periodically updated. You
can download firmware and software updates from the LeCroy website.
Since software is continuously updated, the dialog boxes and menus you see in your program
may be slightly different than what is shown in this manual. These differences should not affect
your understanding of correctly operating the MS-500.

MS-500 Mixed Signal Oscilloscope Option
12 ISSUED: June, 2009 MS-500-OM-E Rev C
DESCRIPTION OF OPERATION
The various components of the MS-500 Mixed Signal Oscilloscope Option acquire and store
digital data, trigger on digital patterns, interface the external module to the oscilloscope, and
provide a user-friendly interface for control and interpretation of data.
The MS-500 is an external device that digitally samples waveform data at up to 2 GS/s (for 500
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, and does not require the
user to input a clock.
While in SINGLE, NORMAL, or AUTO trigger mode, the MS-500 repeatedly samples each digital
channel’s voltage level. If the voltage is greater than the threshold voltage, the MS-500 stores a 1
in internal memory. Otherwise, a 0 is stored.
1
Threshold level
1 1 1 1 1 0 0 0 0 1 1 1 1 1 0 0 0 0 0
The minimum high voltage level is user definable by the hysteresis control up to 1.4 V above the
threshold. The maximum low voltage level is user definable by the hysteresis control up to 1.4 V
below the threshold. The minimum signal swing is 100 mV. The indeterminate range of 50 mV
around the threshold voltage level is the level below which the MS-500 will not operate. However,
the MS-500 can support a signal as low as 100 mV only if the input signal’s quality is adequate.
The MS-500 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
USB2.0 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 then
displayed on the oscilloscope grid 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.
The MS-500 both samples incoming data and searches for trigger conditions.
The USB2.0 cable provides downloading of trigger conditions from the oscilloscope to the MS-
500 and uploading of digital data from the MS-500 to the oscilloscope.
