Output Amplifier
Output configuration: 2 Outputs- Complementary
Output resolution: 16-bit
Maximum output current: 20 mA
Accuracy error: Less than 0.2 5
Linearity error: ±0.5 LSB (INL) (typical)
±0.5 LSB (DNL) (typical)
Output ranges: ± 10 V
± 5 V
± 2 V
± 1 V
± 500 mV
± 200 mV
Output slew rate: 2.3 V/µs
Settling time (G=1, 10 V step): 5 µs
Output impedance: 0.001 Ω
Isolated Stimulator Output (PowerLab 15T & 26T)
Output configuration: Constant-current stimulator with hardware limited
repitition rate
Isolation rating: 4000 V
rms
to ground as per IEC60601-1
2000 V
rms
to Bio Amp inputs
Pulse duration: 50 - 200 µs (so ware selectable)
Compliance voltage: 100 - 110 V typical
Output current: So ware selectable, but hardware limited to a maximum
of 1000 Hz and 200 µs for safety
Safety indicators: Green and yellow indicators. Green flash indicates
delivery of a valid stimulus. Concurrent green and yellow
flash indicates an out-of-compliance condition.
Safety switch: Provides physical disconnection of the stimulator from
the subject.
External Trigger (not on PowerLab 15T)
Trigger mode: TTL level or contact closure, so ware selectable
Trigger threshold: +1.3 V (rising edge), +1.1 V (falling edge)
Hysteresis: 0.3 V
