epicsdev_tektronix

Python-based EPICS PVAccess server for Tektronix MSO oscilloscopes (4, 5, and 6 Series).

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

This implementation is adapted from epicsdev_rigol_scope and supports Tektronix MSO series oscilloscopes using SCPI commands as documented in the Tektronix 4-5-6 Series MSO Programmer Manual.

Installation

pip install epicsdev_tektronix

For control GUI and plotting: pip install pypeto,pvplot

Control GUI: python -m pypeto -c path_to_repository/config -f epicsdev_tektronix

Features

• Support for Tektronix MSO oscilloscopes (configurable)
• Real-time waveform acquisition via EPICS PVAccess
• SCPI command interface for scope control
• Support for multiple trigger modes (AUTO, NORMAL, SINGLE)
• Configurable horizontal and vertical scales
• Channel-specific controls (coupling, offset, termination)
• Performance timing diagnostics

Command-line Options

• -a, --autosave: Autosave control
• -c, --recall: if given: disable recalling of autosaved PVs
• -C, --channels: Number of channels per device (default: 4)
• -d, --device: Device name for PV prefix (default: 'tektronix')
• -i, --index: Device index for PV prefix (default: '0')
• -r, --resource: VISA resource string (default: 'TCPIP::192.168.1.100::INSTR')
• -v, --verbose: Increase verbosity (-vv for debug output)

Example Usage

python -m epicsdev_tektronix.mso -r'TCPIP::192.168.1.100::4000:SOCKET'

Control GUI: python -m pypeto -c path_to_repository/config -f epicsdev_tektronix

Supported Tektronix Models

• MSO44, MSO46, MSO48 (4 Series)
• MSO54, MSO56, MSO58 (5 Series)
• MSO64 (6 Series)
• Other MSO series models using compatible SCPI commands

Performance

Acquisition time of 6 channels, each with 1M of floating point values is 2.0 s. Throughput maxes out at 12 MB/s.
