This module is designed as a current source for I-V measurements or flux bias.
[RANGE] setting the current range (1uA..20mA/V)
The inner pin of the mcx-coax (4) connector is the output node delivering the selected current/voltage, the other mcx inner (2) is connected to ground when in [single] mode
The [Symmetric] mode makes it possible to have opposit polarity output potential, instead of one pin (2) being the ground, pin(2) now becomes an output with the opposite voltage of pin(4)
When the output voltage exceeds 2..4 Volt (depends on loadresistance) an overload LED indicates [clip]. The sample resistance is then too high for the given current.
The [RANGE] switch sets the output current/voltage at 1V control voltage input Maximum control voltage is +/-2V.
[I]output: Iout = Vin * [RANGE]
