asrl

Go-based implementation of an Asynchronous Serial (ASRL) interface for Interchangeable Virtual Instrument (IVI) drivers.

Overview

The asrl package enables controlling test equipment (e.g., oscilloscopes, function generators, multimeters, etc.) over serial port. While this package can be used by itself to send Standard Commands for Programmable Instruments (SCPI) commands to a piece of test equipment, it also serves to provide an Instrument interface for both the ivi and visa packages. The ivi package provides standardized APIs for programming test instruments following the Interchangeable Virtual Instrument (IVI) standard.

Usage

dev, err := asrl.NewDevice("ASRL::/dev/tty.usbserial-PX8X3YR6::9600::8N2::INSTR")
if err != nil {
    log.Fatal(err)
}
defer dev.Close()

ctx := context.Background()

// Query the instrument identification.
idn, err := dev.Query(ctx, "*IDN?")
if err != nil {
    log.Fatal(err)
}
fmt.Println(idn)

// Send a SCPI command.
if err := dev.Command(ctx, "OUTP ON"); err != nil {
    log.Fatal(err)
}
