(6) CURRENT OUTPUT connector
BNC connector providing the current output signal; scaling is set by CURRENT
OUTPUT SENSITIVITY (V/nA) switch 46, filter is set by CURRENT OUTPUT
FILTER LOWPASS (Hz) switch 7.
(7) CURRENT OUTPUT FILTER LOWPASS (Hz) switch
16-position rotary switch to select the corner frequency of the LOWPASS
FILTER (range: 20 Hz to 20 kHz) for the CURRENT OUTPUT connector (6).
(8) CURRENT FROM HEADSTAGE (0.1V/nA) connector
BNC connector providing a voltage proportional to the current at the electrode
with a fixed scaling of 100 mV / nA. This current signal is not filtered.
CURRENT set unit
The CURRENT set unit consist of (9) CURRENT nA potentiometer, (10)
+/0/- switch and (11) GATE / HOLD switch.
(9) CURRENT nA potentiometer
Ten-turn potentiometer for generating a holding current (switch 11 in HOLD
position) or a gated stimulus (switch 11 in GATE position) in CC / BRIDGE or
CCx10 mode, range: 10 nA (100 = 1 nA) or 100 nA (100 = 10 nA),
respectively. Polarity is set by the switch 10.
(10) +/0/- switch
Switch for setting the polarity of the holding current or gated current stimulus,
respectively (see also 9). In zero position the holding current or gated current
stimulus is disabled.
(11) GATE / HOLD switch
Switch that determines the function of the CURRENT nA potentiometer 9 (see
also 9).
