Low Current Multiplexer Card, 10 Channels, 30V / 100mA.
For Datalogger 3706A.
The Keithley 3761 provides quality low-current switching. The offset current error generated
is specified <1pA, with typical performance at <30fA. When used with a voltage source and an electrometer
or picoammeter, this card can easily automate insulation resistance tests, reverse leakage tests on semiconductor
junctions, or gate leakage tests on FETs.
Single 1x10 low current multiplexer
Channels per card: 10

Signal LO is common for all 10 channels and output. When open, signal
HI is shorted to signal LO in current mode. When open,
signal HI is high impedance in voltage mode.

Max. signal level: 30 V, 100 mA peak (resistive load)
Contact life: >106 closures at max. signal levels; >107 closures cold switching or at low signal levels
Contact resistance: <1 Ohm
Contact potential: <200 µV
Offset current: <1 pA (<30 fA typ.)
3dB Bandwidth 1 MHz typ.
Actuation time: <1 ms, excl. of mainframe
Channel isolation: >1014 Ohm, <50 pF
Common mode isolation: >109 Ohm, <150 pF
Common mode voltage: <30 V max.
