SMU Output to Banana Test Lead/Adapter Cable
Model 2600-BAN (2600 Series)
Introduction
This document contains information on the Model 2600-BAN SMU Output to Banana Test Lead/Adapter
cable. This cable connects Category I SMU connections on the rear panel of a Model 260x Series
SourceMeter
®
Instrument to banana test leads.
WARNING Maximum floating (common mode) voltage for a SMU is 250V. Exceed-
ing this level could damage the instrument and create a shock hazard.
Using an external source to float a SMU could create a shock hazard
in the test circuit. A shock hazard exists whenever >42V peak is
present in the test circuit.
NOTE
If applicable, remove terminal block(s) before using the Model 2600-BAN.
The Model 2602 can use two terminal blocks (one for each SMU channel),
and the Model 2601 has one terminal block for the single SMU.
A terminal block can be removed from the rear panel by loosening the two
captive retaining screws and pulling them off the rear panel.
When the Model 2600-BAN is connected to the SMU connection, input/output
LO can be connected to chassis ground by inserting the white banana jack to
the rear panel chassis ground banana jack ( Figure 2 ).
