3.3.9 Remote Probe Connector

The 2010B is a single-split configuration analyzer, the Remote Probe

connector is used to interface the Analysis Unit. See Figure 3-6.

Figure 3-6: Remote Probe Connector Pinouts

The voltage from these outputs is nominally 0 V for the OFF and

15 V dc for the ON conditions. The maximum combined current that can be
pulled from these output lines is 100 mA. (If two lines are ON at the same
time, each must be limited to 50 mA, etc.) If more current and/or a different
voltage is required, use a relay, power amplifier, or other matching circuitry
to provide the actual driving current.

In addition, each individual line has a series FET with a nominal ON

resistance of 5 ohms (9 ohms worst case). This could limit the obtainable
voltage, depending on the load impedance applied. See Figure 3-7.
