These cables establish current limiting (2 ma target limit, 2.2 ma maximum) over a compliance voltage range of ±200 volts and are primarily used with the STMISOLA for tDCS and tACS stimulation as a safety precaution.
Choose
The CBLLIMIT2 cable will permit any unipolar current between 0 and 2 ma to pass. The CBLLIMIT2AC cable will permit any bipolar current between 0 and ±2 ma (p-p) to pass.
The CBLLIMIT2 and CBLLIMIT2AC current limiting cables are factory tunable for a range of current limits (typically 1-20 ma) and may have other uses where a current limit is required, such as during general purpose electrical stimulation protocols. These current limiters can be set to insure that dangerous current levels are avoided, despite possible system errors.

The figure below shows a sample setup for HD-tDCS using CBLLIMIT2 and other BIOPAC hardware:
Learn a technique—Trans-radial Electrical Bioimpedance Velocimetry (TREV)—that is more user-friendly and less invasive than the transthoracic method. TREV measures blood movement in the radial and ulnar arteries of the forearm via bioimpedance.
Topics Covered:
– Presentation and discussion of TREV
– Derived Indices Relevant to TREV
– Hardware setup
– Participant setup
– Recognizing good quality and bad quality data
– Demonstration with the grip anticipation test
– Review of results from other tests
