This module is a combination (of the PCBoards) of 3 modules:S3b,M1b,M0b.
All specs can be found at the infopages of these modules.
The Iso-out part is M0b and this one is compatible with both IVV and SPI-rack and has lower drift and 1/F noise. this makes it the preferred version compared to VIa.
Although specs are the same, because of limited frontpanel space some functions are skipped and the Lemo-connectors are replaced by the smaller MCX connectors (see picture).
Functional differences for the Imeas compared to M1b:
The ground/float switch is skipped, you do not loose functionality, the mcx labelled "gnd/ref" can be connected to either ground or a reference voltage (allowing groundlift).
The 2 switches "lowRin/LowNoise" and "postgain" have been combined in one
You loose some combination settings
now you get: x100ac with low noise/low Rin with x1/low noise with x1
