Si8000m / Si9000e Excel interface – new for 2026:
The Si Excel interface allows customers to access Polar impedance field solvers via Microsoft Excel(R) user defined function calls.
This single installer replaces legacy 32 bit and 64 bit Si Excel versions.
a) Overcomes some of the latency issues reported with network licenses on the existing 64 bit compatible Si Excel
b) Now includes a full set of functions for all available Si8000 / Si9000 impedance structures in expert mode where previously only a subset of Si8000 structures were exposed.
c) When deployed, supports both 64 and 32 bit Microsoft Excel.
If you are an existing customer please contact polarcare@polarinstruments.com for migration information as you will need to make minor changes to existing spreadsheets.
