The Tektronix 1103 TEKPROBE Power Supply provides external power to accessories and probes when the oscilloscope or similar instrument does not have the capability to do so.

The 1103 can operate at either 115 VAC or 230 VAC nominal voltage. Optional power cords are available to provide compatibility with different power source connections. The power supply has overload protection. It has a power switch on the rear panel and a power indicator on the front panel.

The 1103 allows probes that need TEKPROBE interface power to be used with any oscilloscope or digitizer that does not provide TEKPROBE power. The 1103 has connections and offset controls for two probe channels. Each channel has a TEKPROBE connectorr (that combines power output and signal input), a BNC signal output connector, an offset enable switch (with LED). and fine and coarse controls. The offset controls enable the user to set an offset voltage for probes such as the Tektronix P6701, P6702, P6703 optical to electrical converters, and for active probes such as the Tektronix P6203, P6204, P6231, and P6501 Active Probes (when used with appropriate power cord). The 1103 provides +5 VDC, -5 VDC, +15 VDC, and -15 VDC at the probe connector.
