4-wire common-side (CSID) ohms measurements (7701 module)

For normal 4-wire ohms measurements using a switching module, channels are paired to
provide the switch paths for input and sense. Each tested DUT requires two input
channels. For example, the 7700 module has 20 channels. With the Ω4 function selected,
channel 1 is paired to channel 11, channel 2 is paired to channel 12, and so on. This
configuration allows up to 10 DUT to be tested.
The 7701 module has 32 input channels. For normal 4-wire ohms measurements, up to
16 DUT can be tested. However, this module can be configured for common-side (CSID)
4-wire ohms measurements, allowing up to 32 DUT to be tested.
With a 7701 module installed, the 4-wire ohms mode can be selected using the following
key-press sequence:
1.
2.
3.
4.
For remote programming, the following commands are valid with a 7701 module
installed:
SYSTem:FRESistance:TYPEx, NORMal
SYSTem:FRESistance:TYPEx, CSIDe
SYSTem:FRESistance:TYPEx?
Where the x in TYPEx is the slot number for the 7701 module.
NOTE
Press SHIFT and then press CARD.
Select CONFIG.
Select slot that has the 7701 (i.e., SLOT1: 7701).
Select 4W MODE: NORM (normal) or CSID (common-side).
Details on 4-wire common-side ohms measurements using the 7701 module are
provided in the manual (packing list) supplied with the module.
