Note:

  • The multi-channel system power supplies HP 6621A, 6622A, 6623A, 6624A, 6625A, 6626A, 6627A & 6628A share some of the command syntax and could probably be incorporated in this implementation

  • The B-version of these models (6632B, 6633B & 6634B) are SPCI-compliant and could be implemented in a similar manner

class pymeasure.instruments.hp.HP6632A(adapter, name='Hewlett-Packard HP6632A', **kwargs)

Bases: HPLegacyInstrument

Represents the Hewlett Packard 6632A system power supply and provides a high-level interface for interacting with the instrument.

class ERRORS(value, names=None, *, module=None, qualname=None, type=None, start=1, boundary=None)

Bases: Enum

Enum class for error messages

property OCP_enabled

A bool property which controls if the OCP (OverCurrent Protection) is enabled

property SRQ_enabled

A bool property which controls if the SRQ (ServiceReQuest) is enabled

class ST_ERRORS(value, names=None, *, module=None, qualname=None, type=None, start=1, boundary=None)

Bases: Enum

Enum class for selftest errors

check_errors()

Method to read the error status register

Return error_status

one byte with the error status register content

Rtype error_status

int

check_selftest_errors()

Method to read the error status register

Return error_status

one byte with the error status register content

Rtype error_status

int

clear()

Resets the instrument to power-on default settings

property current

A floating point property that controls the output current of the device.

(dynamic)

property delay

A float property that changes the reprogamming delay Default values: 8 ms in FAST mode 80 ms in NORM mode

Values will be rounded to the next 4 ms by the instrument

property display_active

A boot property which controls if the display is enabled

property id

Reads the ID of the instrument and returns this value for now

property output_enabled

A bool property which controls if the output is enabled

property over_voltage_limit

A floationg point property that sets the OVP threshold.

(dynamic)

reset_OVP_OCP()

Resets Overvoltage and Overcurrent protections

property rom_version

Reads the ROM id (software version) of the instrument and returns this value for now

property status

Returns an object representing the current status of the unit.

status_desc

alias of Status

property voltage

A floating point proptery that controls the output voltage of the device.

(dynamic)
