Global description of the source/measure modules:
All modules have one or more function-controls to set things like: gain, mode etc. Usually this is done by knobs on the module. On the backplane there are some voltage control/readout lines that will be described below.
The routing of the voltage control-lines can be changed by the user in the so-called "summing module" S2 (see also IVVI-doc)
Source modules have one (or two) differential control-voltage inputs that can be driven by a DAC (D5-unit) and/or a signal from an iso-amp (e.g. for lock-in type measurements). In the summing module (S2) these inputs are labelled, for example: AV1, AV2 (slot A, control voltage 1, control voltage 2).
Measure modules have a value-output voltage that is fixed-routed to one of the iso-amp outputs (channel set by the slot it is in). Measure slots also offer two (rarely used) differential control-voltage inputs (labels Ma, Mb) to set certain parameters if implemented (example:treshold for comparator in M3).
1V is considered to be the full-scale for the source-value-control and measure-signal-output. Example: setting the current source on 1uA means +/-1V control will give +/-1uA.
Depending on the source/measure module there is some additional headroom (all iso-amps go to more than +/3V). Measure modules usually have a factor of 3 headroom (reason:what you measure is not known and usually noisy so dynamic range is important).
Source modules have less headroom (10..100%) because you are aware of what you are sending so noise level is optimised instead of dynamic range.
note:(#) Modules labelled with "remote control" (function) control have no knobs but need control from a control panel and fit only in the obsolete SMS and the very first obsolete version of the IVVI-rack.
All other modules have manual control and fit in all systems (but have no remote function control when used in the SMS rack).
Modules with "remote control" like S1,S3,M1 are still in use but labelled "obsolete" and can no longer be produced and cannot be used in the current version of racks.
