The Sig. Gen.Out BNC connector is lightly filtered using an RLC circuit. It has a bandwidth of
approximately 3 MHz when connected to a high-impedance input. This bandwidth is further reduced if a
coaxial cable is connected to the BNC. Its output impedance is approximately 200 Ω in parallel with 220
pF.
Aux. In BNC
The Aux. In BNC connector allows you to measure a
voltage from outside the Reference 600+ using the
Reference 600+’s internal A/D. The scaling is 3 V
input equals 30 000 A/D counts. This is a
resolution of 100 µV per bit. Results are reported in
volts. The input is differential (see Appendix D).
The allowed input voltage range is –24 V to +24 V.
Consult Appendix D for additional information
concerning this connector.
Caution: The shell of the Sig. Gen.Out BNC is connected to the Reference 600+’s
Floating Ground. Connection of this BNC to a piece of earth-ground-referenced equipment can
compromise the Reference 600+’s ability to float, and invalidate data collected on earth-grounded
cells.
