3. BA-01X System
This manual is related to the standard configuration of the BA-01X system consisting a
standard headstage and standard calibrations of bridge balance, electrode resistance display
range etc.
Other configurations are available, e.g. if the BA-01X system is used only for whole cell
patch clamp recordings with suction electrodes the BA-01X system can be delivered with
adapted calibrations and a low noise / low bias current headstage (see Optional accessories in
chapter 2). For details contact npi.

System Description
The npi BA-01X intracellular recording systems are precise current clamp instruments with a
bridge circuit to compensate for the resistance of the recording intracellular electrode. For
current injection and potential recording a very high impedance voltage-to-current converter
with a special input capacitance compensation circuit is used. For methodical reviews see
Lalley et al. (1999), Richter et al. (1996), Ogden (1994) and Boulton et al. (1990).
