The Tektronix 1103 is a standalone probe power supply that enables probes with Tekprobe BNC connectors to be used with older equipment.
The original version uses a traditional linear power supply with a mains-frequency transformer and LM317T / LM337T regulators.
Later versions changed to an external 12 VDC, 2.5 A supply, with switching regulators providing the four output voltages.
|Power input||87 to 128 VAC (low) or 174 to 250 VAC (high), 48 to 440 Hz, ≤35 W|
|Power output||+15 V, −15 V, +5 V, −5 V ; ±2% each ; ≤300 mA each|
|Offset control||+1 to −1 V, course and fine control, 0 V when disabled|
