Welcome
Thank you for purchasing a Teledyne LeCroy MS-500.
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 to the Teledyne LeCroy 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 coincident with digital signals. Users can
easily debug signals using standard oscilloscope tools such as cursors,
measurement parameters, and zooming. Both oscilloscopes compatible
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.
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. Both are referred to as MS-500 in this manual.
This MS-500 manual assumes that you have a basic understanding of
discrete electronics, logic analyzers, and Teledyne LeCroy oscilloscopes,
specifically the model you will use with the MS-500. When necessary,
details on specific oscilloscope features are included in this manual.
Contact your nearest Teledyne LeCroy customer service center or national
distributor if anything is missing or damaged. We can only be responsible
for replacement if you contact us immediately.
Sincerely,
David C. Graef
Teledyne LeCroy Corporation
Vice President and Chief Technology Officer

Connect and disconnect properly.
Do not overload. To avoid electric shock or fire, do not apply any potential
to the signal leads that exceeds the maximum rating of the instrument.
Refer to Specifications section of the manual for details.
Comply with voltage derating curve. When measuring higher frequency
signals, comply with the Voltage vs. Frequency Derating Curve, contained in
the Specifications section of the manual.
Use only within operational environment listed. Do not use in wet or
explosive atmospheres.

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 Teledyne LeCroy service center so that they can
ascertain whether this component is defective.
If you need to return a Teledyne 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 Teledyne 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.
Teledyne 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 Teledyne LeCroy Web site at teledynelecroy.com
for the center nearest you.
Staying Up-to-Date
Your MS-500 hardware does not need periodic calibration.
Teledyne 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
Teledyne 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.
