IX2-700 Dual Intracellular Preamplifier

DIFFERENTIAL RECORDING

The IX2-700 can be used for differential recording using Channel 1 and

Channel 2. The 10 (V

voltage less the Channel 2 voltage. You must be certain both channels are properly

zeroed with their DC offsets as any offset will also be subtracted from the other

channel. There is an internal trimpot for common mode rejection ratio adjustment

that has been factory set. This adjustment assures that the output is zero when the

outputs from channels 1 and 2 are equal. Should you need to adjust the trimpot,

contact the factory for explicit instructions.

The Cx control is for cross capacitance nulling to adjust for variations in

dynamic response time between Channel 1 and Channel 2.

Since the selection of available probes includes one with an input impedance

greater than 10

ohms the differential mode may be used directly with ion

selective electrodes (i.e. channel 1 connected to the ion sensitive electrode). The

output resistance is 600 ohms with a range of +/- 13 volts.

UNUSED CHANNEL

If you are only using one of the two channels, either unplug the unused 15

pin rear panel connector or connect the unused headstage input connector through

a resistance or directly to ground (ROD).
