Digital Multimeters +++++++++++++++++++ Agilent 34410A ^^^^^^^^^^^^^^ `Agilent `_ multimeters (now `Keysight `_) are supported in Karabo via the LAN interface and SCPI protocol. A list of supported features is: * DC and AC current measurement * DC and AC voltage measurement * Resistance measurement * Capacitance measurement * Frequency and Period measurement * Temperature measurement The Karabo device has been developed for use with `34410A `_, but it is likely to work with other models. .. _keithley/Multimeters: Keithley Multimeters ^^^^^^^^^^^^^^^^^^^^ `Keithley `_ multimeters from Tektronix are supported in Karabo via the LAN interface and SCPI protocol. Various models are supported and are all contained in one package: `keithleyMultimeters `_. Manuals are available here as well in the doc folder. Supported models: * 6514: `Programmable Electrometer `_ * DMM6500: `Digital Multimeter `_ * 2470: `Graphical SourceMeter SMU `_ * 6487: `Picoammeter/Voltage Source `_ * 2611: `SourceMeter SMU `_ * 2700: `Multimeter/Data Acquisition/Switch Systems `_ * 6430: `Sub-Femtoamp Remote SourceMeter `_ Most models have: * DC and AC current measurement * DC and AC voltage measurement * Resistance measurement * Capacitance measurement The models 2611, 2700 and 6430 where brought by users and are not part of XFEL property. Ophir Nova 2 ^^^^^^^^^^^^ `Ophir `_ laser power meters are supported in Karabo with the use of Lantronix ethernet to RS-232 converters. Ophir makes use of a custom ASCII protocol. The `Ophir Nova II `_ spports several heads for different types of measurements. A list of supported features is: * Power measurement (watts) * Energy measurement (joules) * Frequency measurement (hertz) Other meters from Ophir should be supported out of the box.
