HP 3478A Calibration Utility

A command line utility that reads, writes and verifies HP 3478A meter calibration data via GPIB.

Offsets and gains are displayed for each calibration entry/meter range.

Supported Hardware

This utility supports Prologix GPIB-USB compatible controllers including the Galvant Industries GPIBUSB rev4 with firmware version 6.

Utility Details

NAME
    HP3478ACalibration

SYNOPSIS
    HP3478ACalibration -f FILE [-o]
    HP3478ACalibration -f FILE -r ADDR [-o]
    HP3478ACalibration -f FILE -w ADDR [-o]
    HP3478ACalibration -h

DESCRIPTION
    HP3478ACalibration reads, writes and verifies HP 3478A meter calibration
    data. Reading and writing of the calibration data is performed using a
    Prologix GPIB-USB compatible adapter.

OPTIONS
    -f FILE, --file=FILE
        Use FILE as the calibration file. The calibration file is verified for
        correctness when both the -r and -w options are not specified.

    -o, --allow-oversize
        Allow calibration files larger than 256 bytes to be read. (Only the
        first 256 bytes of the calibration file will be used when this
        option is specified.)

    -r ADDR, --read=ADDR
        Read calibration data from the instrument with GPIB address ADDR
        into the calibration file specified by -f. (This option cannot be
        specified with option -w.)

    -w ADDR, --write=ADDR
        Write calibration data from the calibration file specified by -f to
        the instrument with GPIB address ADDR. (This option cannot be
        specified with option -r.)

    -h, --help
        Display this help.

Examples:

Read calibration from meter at GPIB address 23 to file:
HP3478ACalibration -f file.cal -r 23

Write calibration from file to meter at GPIB address 23:
HP3478ACalibration -f file.cal -w 23

Verify a calibration file and display offsets/gains:
HP3478ACalibration -f file.cal
