NOTE: The BOP is operating as a SOURCE if the direction of its output voltage is the same as the
direction of its output current. The BOP is operating as a SINK if the direction of its output
voltage is opposite that of its output current. An illustrative case is shown in FIG. 1-3, where
the BOP is programmed to deliver a sine wave output and where the load produces a phase
shift between the output voltage and current.

REFERENCES: Two reference/bias sources (± 10V - 1 mA MAX.) are provided for control
and biasing purposes. These reference sources are available at the rear programming
connector (with reference to the “COMMON” terminal). Their specifications are tabulated in
Table 1-2.
C) OFFSET NULLING: Controls are provided to zero the initial offsets (E
io
, I
io
) of both the volt-
age and current control preamplifiers.
D) LOAD REACTANCE: To realize the full high speed potential of the BOP, the load charac-
teristics should be mainly resistive. Load capacitance and inductance up to 0.01
µ
F and 0.5
mHy respectively can be tolerated without performance deterioration.
CAUTION
:
Stable operation into a purely inductive load in the Current Mode of opera-
tion requires a minimum series resistance of 25 ohms.
E)
SERIES OR PARALLEL OPERATION: Not recommended.
