In manual operation every set value can be set in the increments given above. In this case
the actual output values set by the device will lie within percentage tolerances as shown in the
technical data sheets. These will inuence the actual values.
1.9.5.5 USB-Port (Front side)
The frontal USB port, located to the right of the rotary knobs, is intended for the connection of standard USB sticks
(stick). This can be used for loading or saving sequences for the arbitrary function generator.
USB sticks must be FAT32 formatted and have a maximum capacity of 32GB.Allsupportedlesmustbeheldin
a designated folder in the root path of the USB stick in order to be found. This folder must be named HMI_FILES,
such that a PC would recognise the path G:\HMI_FILES if the drive were to be assigned the letter G. The control
paneloftheelectronicloadcanreadthefollowingletypesfromastick:
wave_u<arbitrary>.csv
wave_i<arbitrary>.csv
Function generator arbitrary function for voltage (U) or current (I)
The name must begin with wave_u / wave_i,therestisuserdened.
