Page 2: Features And Applications
The PB-503 eliminates the clutter and confusion that often results when constructing sophisticated circuits. Alligator clips and similar connectors are seldom needed. Sockets on the PB-503 allow insertion of components or wires of up to 20 gauge. A detailed panel layout and description of the PB-503 is given in the section “Description of Individual Features”. - Page 3 Digital-to-Analog Converters Medium Scale Integration Circuits Phase Lock Loops Operational Amplifiers 3 PB-503 COURSEWARE Courseware is available separately through our website or as part of the PB-503LAB package. The PB-503LAB package offers comprehensive course instruction covering the following areas: Electronic...

4.1 AC Line Input The PB-503 can run off of 115 or 230 VAC. The unit comes standard with a fuse for 115 VAC. In order to use with 230 VAC, please slide the switch on back to 230 V. You will also need to replace the fuse with a 5 x 20 mm time lag fuse that is rated at 0.25 A... - Page 6 DC offset controls for op amps, and timing circuit controls. All leads for both potentiometers are available and uncommitted. 4.7 BNC Connectors The PB-503 may be connected to other pieces of equipment via two BNC connectors. This allows the use of shielded cable to minimize noise and interference. 4.8 Switches Two single pole, double throw (SPDT) switches are provided for general switching functions.

7 BREADBOARDING TECHNIQUES This section contains information which may prove useful when constructing circuits using the PB-503. While there are no hard and fast rules for breadboarding, the following tips may save time and trouble. Unless a circuit is being prepared for a demonstration or display, avoid cutting component leads very short. - Page 11 If you have a need for any calibration or repair services, please visit us on the web at: globalspecialties.com.
