class Kt34400System

Kt34400System interface.

beep(self: keysight_kt34400.keysight_kt34400.Kt34400System) → None

This method issues a single beep immediately from the instrument.

Returns:

None

Remarks:
  • Selecting this method overrides the current beeper state. This means that you can issue a single beep even if BeepEnabled is False.
    • property beep_enabled

    This method enables or disables the beeper tone.

    Access:

    ReadWrite

    Type:

    bool

    clear_io(self: keysight_kt34400.keysight_kt34400.Kt34400System) → None

    Performs an IEEE 488.1-style clear of the device.

    Returns:

    None

    property io_timeout

    Gets or sets the I/O timeout.

    Access:

    ReadWrite

    Type:

    datetime.timedelta

    property license_catalog

    Returns a comma separated list of installed, licensed options.

    Access:

    ReadOnly

    Type:

    str

    Remarks:
  • Only those installed options that require a license are returned.
  • Options vary by model.
    • property lock_name

    Read Only - Returns the current I/O interface.

    Access:

    ReadOnly

    Type:

    str

    Remarks:
  • Return values are "USB", "VXI11", "GPIB", or "LAN <IP Address>" indicating the I/O interface being used by the querying computer.
    • property lock_owner

    Read Only - Returns the I/O interface that currently has a lock.

    Access:

    ReadOnly

    Type:

    str

    Remarks:
  • Returns "USB", "VXI11", "GPIB", or "LAN <IP Address>" indicating the I/O interface that currently has a lock. If no interfaces have a lock, "NONE" is returned.
    • lock_release(self: keysight_kt34400.keysight_kt34400.Kt34400System) → None

    Decrements the lock count by 1 and may release the I/O interface from which the command is executed.

    Returns:

    None

    Remarks:
  • When a lock is active, Bit 10 in the Standard Operation Register will be set. When the lock is released on all I/O interfaces, this bit will be cleared.
    • lock_request(self: keysight_kt34400.keysight_kt34400.Kt34400System) → bool

    Requests a lock of the current I/O interface.

    Returns:

    Returns true if the lock request is granted or false if denied.

    Return type:

    bool

    Remarks:
  • This provides a mechanism by which you can lock the instrument's configuration or cooperatively share the instrument with other computers.
  • Lock requests can be nested; each request increases lock count by 1. For every request, you will need a release (LockRelease()) from the same I/O interface.
  • Locks are handled at the I/O interface level (USB, LAN, etc.) and you are responsible for all coordination between threads and/or programs on that interface.
  • When a request is granted, only I/O sessions from the present interface will be allowed to change the state of the instrument.
  • LAN sessions locks are automatically released when a LAN disconnect is detected.
  • Granting a lock sets Bit 10 in the Standard Operation Register.
    • property power_line_frequency

    Sets the line frequency with a 20 ms delay.

    Access:

    ReadWrite

    Type:

    PowerLineFrequency

    Remarks:
  • Default value is PowerLineFrequency.Freq50
    • preset(self: keysight_kt34400.keysight_kt34400.Kt34400System) → None

    Returns:

    None

    Remarks:
  • This method does not affect any previously-stored instrument states

  • The USBHost parameter refers to the instrument's front panel USB port.
  • If you disable the LAN interface, none of the associated LAN services will be started when you power on the instrument.
  • For HiSLIP, LAN, SOCKets, TELNet, VXI11, or WEB on the 34460A, you must have option 34460A-LAN or option 3446LANU.
  • The interface enable settings are stored in nonvolatile memory. They do not change when power has been off, after a Factory Reset or after an Instrument Preset.
