The Tektronix 1103 is an accessory power supply that provides external power to TEKPROBE BNC Interface probes. The Tektronix 1103 allows customers to use probes requiring TEKPROBE interface power with any oscilloscope or digitizer that does not provide TEKPROBE BNC power. The Tektronix 1103 offers two independently controlled channels consisting of a TEKPROBE BNC interface input, a voltage offset control (providing variable offset or no offset) and BNC signal output.
The offset control supplies a voltage, adjustable via the front panel control. This offset control is available for TEKPROBE BNC probes with this capability. These include: P6235, P6245, P6246, P6247, P6248, P6249 and P6330.
The characteristics for TEKPROBE BNC Interface probes are subject to change when used with the 1103 TEKPROBE Power Supply. Bandwidth, Rise-time, Propagation Delays will generally differ from the advertised probe only specification. These are dependent upon:
1) the cable length from the output BNC connector to the oscilloscope input
2) the instrumentation input impedance the output BNC is being connected to
3) any additional adapters required to properly interface to the test instrumentation.
