MS-500 Mixed Signal Oscilloscope Option

6ISSUED: 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.
