DESCRIPTION OF INDIVIDUAL FEATURES
In order to properly use the full capabilities of the PB-505 it is highly recommended that
the user become familiar with the panel layout and the features of the components, (see
Figure 1 below)
POWER SUPPLIES
By combining the three DC power supplies on the PB-505 the user may work with
virtually any type of integrated circuit or discrete component. The fixed 5V supply has
become an industry standard for powering digital IC's. IC's which require +5V, +12V,
and -5V are easily accommodated by the PB-505. The variable supply output voltages
may be changed by using the adjustment knobs on the front panel. The positive and
negative outputs are continuously variable from +1.3 to +15V and -1.3 to -15V
respectively. Both variable supply outputs are referenced to circuit common. This
creates a split supply which is often used with differential and operational amplifiers (op-
amps).
