(picture prototype)
This module is designed as a versatile source for V-I or I-V measurements.
The [Source mode] switch sets the module operating as:
[V] a voltage source with [RANGE] setting the current limit to approx 3x(1nA..10mA)
[V+R] a voltage source with [RANGE] setting the output resistance (1Gohm..100ohm)
[I] a current source with [RANGE] setting the current range (1nA..10m A/V)
The [R-out] switch makes it possible to set the output resistance of the selected [V] or [I] source (R is set by 1/[RANGE]). The R/1000 1000R, being the usual setting, gives the highest accuracy. The R/10 10R gives the lowest noise.
The inner pin of the mcx-coax connector is the output node delivering the selected current/voltage, the other side connected to ground
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 or to low for the given voltage.
The [RANGE] switch sets the output current/voltage at 1V input.
[I]output: Iout=Vin * [RANGE]
[V]output: Vout=Vin
for IVVI-rack only: using this module means that only ONE source can be used in the rack.
(both Iso-amps are used then to provide the 2 control signals
