Instruments¶

Agilent MultiMeter¶

class sls_detector_tools.AgilentMultiMeter(host, port)[source]¶

Bases: object

clearVals()[source]¶: Clears the output values outVals

measure()[source]¶: Does one measurement with the open instrument, adds the measured value to the outVals and returns it

measureNtimes(N)[source]¶: Does N measurements with the open instrument and calculates the average, adds the averaged value to the outVals and returns it

writeVal(v)[source]¶: AgilentMultiMeter.writeVals(v) Writes v into the output values outVals

Keithley SourceMeter¶

class sls_detector_tools.SourceMeter(verbose=False)[source]¶

Bases: object

Class to control a Keithley 2410 SourceMeeter over serial interface

close_port()[source]¶

data_elements()[source]¶: Set output data elements from the Keithley now set to Voltage Current and Time

get_digits()[source]¶

off()[source]¶

on()[source]¶

open_port(port='/dev/ttyUSB0', baudrate=9600, parity='N', stopbits=1, bytesize=8, xonxoff=0, timeout=1)[source]¶: Open serial port to communicate with the Keithley make sure that it’s set up in a matching way and that port number is correct

read()[source]¶

remote(flag)[source]¶: Turn on and off remote operation of the keithley , remote(True) locks the physical panel

set_digits(n)[source]¶

set_voltage(V)[source]¶
