Page 15: What The Lsa1000 Does And How
About the LSA1000 What the LSA1000 Does and How The LSA1000 is an ideal instrument for capturing, digitizing and analyzing high-speed electronic signals. Moreover, it has been optimized for system-integration applications with high throughput, ease of use and reliability. The host computer can easily control and retrieve data from the LSA1000 via a 10/100Base-T Ethernet interface.
Page 16: Block Diagram
Block Diagram Signalyst ➢ LSA1000 What Can it Do? The LSA1000 delivers the same powerful performance as a high-end LeCroy DSO (Digital Storage Oscilloscope) in a design optimized for system integration, with: ➢ Capture of one-off (single-shot) events, stored in memory ➢...
Page 17: Input Amplifier
System Acquisition Input Memory Amplifier Memory Signal Up to 64 Mb Processor Record Length Bandwidth Sample Rate Computer Basic Elements These are the basic elements that make up the LSA1000: ➢ Amplifier — amplifies and conditions the input signal so that it can be measured most effectively ➢...
Page 18 About the LSA1000 ➢ Processor — a PowerPC 603e microprocessor controls the entire system and performs computations and special monitoring. ➢ Interfaces — Ethernet port transfers processed data to the host computer and receives remote control instructions. Finding the “Right Fit” For optimum results there must first be a good “fit”...
Page 19: Capture
Capture In addition to the primary specifications and three parameters described above, capture techniques, the triggering system, channels and ADC specification all impact on LSA1000 performance. Acquisition Technique Single-shot acquisition is the LSA1000’s basic acquisition technique, which makes the instrument very suitable for the study of signal phenomena that have a low-repetition rate or are not repeated —...
Page 20 About the LSA1000 Channels The LSA1000 offers two channels for signal input. There are four additional BNC connectors for an external trigger channel, external reference clock in, external reference clock out and acquisition status output. The LSA1000 can be “stacked” to provide more channels and parallel processing with multiple units.
Page 21 The amplitude and range of trigger signals and levels are limited as follows: ➢ ECL or TTL threshold crossing with EXT as trigger source. Upper Region Trigger Level Lower Region Time Triggers Edge Window Trigger: trigger when the signal leaves the window region. ➢...
Page 22 About the LSA1000 Trigger Modes STOP This command halts the acquisition in any of the three re-arming modes: Auto, Normal or Single. Issuing the STOP command prevents the LSA1000 acquiring a new signal. Issue STOP while a single-shot acquisition is under way and the last acquired signal will be kept.
Page 23: Measure
Waveform mathematics can yield final answers instead of raw data. For example, inputs from voltage and current transformers can be multiplied together to calculate power. An important LeCroy LSA1000 feature is the ability to ‘daisy-chain’ math functions: a power trace can be integrated to calculate energy, for instance.

Remote Control is via a subset of the standard LeCroy DSO remote commands with enhancements specific to the LSA1000. TCP/IP protocol is used for Ethernet communication. See the Remote Control Manual.

Page 31 The LSA1000 has not been designed to make direct measurements on the human body. Users who connect a LeCroy instrument directly to a person do so at their own risk. Power Requirements The LSA1000 operates from a 115 V (90–132 V) or 220 V (180–250 V) AC (~) power source at 45–66 Hz, and draws 200 W max power.
Page 32 Cleaning and Maintenance Maintenance and repairs should be carried out exclusively by a LeCroy technician (see Chapter 1). Cleaning should be limited to the exterior of the instrument only, using a damp, soft cloth. Do not use chemicals or abrasive elements. Under no circumstances should moisture be allowed to penetrate the instrument.

Page 35: Connecting The Lsa1000 To Its Host
Connecting to PC or Network Connecting the LSA1000 to its Host This chapter describes connecting the LSA1000 to the host PC or network over the standard 10/100Base-T Ethernet. Windows NT and Windows 95 operating systems are supported. For more about the LSA1000 and the Ethernet, see Chapter 3 of the accompanying Remote Control Manual.
Page 36: Configuring The Pc
Connecting to PC or Network Configuring the PC Before establishing a direct connection between the LSA1000 and the host computer, the PC must first be properly configured. Note: The following A specific TCP/IP address must be assigned — known as "static examples assume that the addressing".
Page 37 3. Double-click on the line. A dialog box similar to the one below appears. Select 4. If this has already been selected, then the computer’s static address is set and nothing more needs to be done. Cancel out of the TCP/IP and network dialog boxes and close the control panel.
Page 38: Verifying Connection
Connecting to PC or Network 5. However, if the address has not already been selected, fill in the IP address and subnet mask as shown above. The subnet mask for 172.25.x.x is 255.255.0.0. If the computer will not be plugged into a network, the above address (or almost any address within the chosen subnet) will do.
Page 39 The ping command has sent a message to the instrument and waited for a response. But if a timeout occurs, as is shown in box on the next page, the IP address used for the destination (the LSA1000) is incorrect or not within the subnet mask of the PC’s IP address.
Page 40: Network Connection
Connecting to PC or Network Network Connection Check with your network administrator before connecting the LSA1000 to a network. Incorrect addresses on a network can cause both the network and the LSA1000 to behave strangely! However, a network connection ought to be as simple as plugging the LSA1000 into the network.
Page 41: Changing Ip Address
Note: The default Gateway is assigned as "172.25.0.1" unless your network has this Gateway available, you must ensure the computer and the LSA1000 are on the same subnet. Changing IP Address Once communication between the LSA1000 and host PC has been verified, the IP address can be easily reset to any address using the Scope Explorer remote control software tool provided in the Getting Started CD-ROM.
