epicsdev_lecroy

Note. Version 1.0.0 was created by github copilot. Python-based EPICS PVAccess server for LeCroy oscilloscopes.

It is based on p4p and epicsdev packages and it can run standalone on Linux, OSX, and Windows platforms.

It was developed using the MAUI Remote Control and Automation Manual and tested with LeCroy/Teledyne oscilloscopes.

Features

• Remote control of LeCroy oscilloscopes via EPICS PVAccess
• Support for multiple channels (configurable, default 4)
• Waveform acquisition and real-time data streaming
• Trigger control and configuration
• Horizontal and vertical scale adjustments
• Panel setup save/recall functionality
• VBS (Visual Basic Scripting) support for advanced control

Installation

pip install epicsdev_lecroy

For control GUI and plotting:

pip install pypeto pvplot

Usage

To start the server:

python -m epicsdev_lecroy -r 'TCPIP::192.168.1.100::INSTR'

Command-line Arguments

• -r, --resource: VISA resource string to access the device (default: TCPIP::192.168.1.100::INSTR)
• -d, --device: Device name for PV prefix (default: lecroy)
• -i, --index: Device index for PV prefix (default: 0)
• -c, --channels: Number of channels (default: 4)
• -v, --verbose: Increase verbosity (-v or -vv)

Examples

Connect via TCP/IP socket:

python -m epicsdev_lecroy -r 'TCPIP::192.168.1.100::1861::SOCKET'

Connect with custom device name:

python -m epicsdev_lecroy -r 'TCPIP::192.168.1.100::INSTR' -d scope1

Control GUI:

python -m pypeto -c path_to_repository/config -f epicsdev_lecroy

Supported Models

This driver should work with LeCroy oscilloscopes that support the MAUI remote control interface, including:

• WaveSurfer series
• WaveRunner series
• WavePro series
• HDO series
• Other Teledyne LeCroy scopes with MAUI interface

SCPI Commands

The driver uses LeCroy SCPI commands and VBS (Visual Basic Scripting) for device control. Key commands include:

• C<n>:TRACE - Enable/disable channel display
• C<n>:VOLT_DIV - Set vertical scale
• C<n>:OFFSET - Set vertical offset
• TIME_DIV - Set horizontal scale
• TRIG_MODE - Set trigger mode (AUTO, NORM, SINGLE, STOP)
• TRIG_SELECT - Set trigger source
• VBS commands for advanced control

Performance

Performance depends on the oscilloscope model, network interface (1GbE vs 10GbE), and memory depth. LeCroy scopes typically provide high-speed data transfer over their network interfaces.

Notes

• The driver uses binary data transfer (WORD format) for efficient waveform acquisition
• Big-endian byte order is used for compatibility
• VBS scripting allows advanced control of scope features not available through standard SCPI
• Some features may vary depending on the specific LeCroy model
