signal control of instruments we bring to beamtime. The signal generator (HMF2525) and oscilloscope (DSOX2014A) are connected via USB to a Raspberry pi. The RPI is placed in the huch and conneted to the network.

The signal generator is set up to listen on port 5006 with the following commands available:

HMF2525_keys = [
    'FUNC',
    'OUTPut',
    'FREQuency',
    'PERiod',
    'VOLTage',
    'VOLTage:UNIT',
    'VOLTage:HIGH',
    'VOLTage:LOW',
    'VOLTage:OFFSet',

    'BURSt:INTernal:PERiod',
    'BURSt:PHASe', #0 to 360
    'BURSt:STATe',
    ]

The oscilloscope listens on port 5007, and can be querried using:

'AvgC1C2?'

which returns the average voltage in the frame on channel 0 and 1 as strings, i.e.:

'AvgC1C2 = 0.9660903434343435, -0.15168975454545452'

'C1C2?'

which returns the 100 voltages in the frame on channel 0 and 1 as strings, i.e.:
