INTRODUCTION
1-2
This instruction manual contains operating and
service instructions
for the HP-1B Isolated D/A Power
Supply Programmer Model
595018. Installation instructions
and sample programs are also provided.
The 59501B.
allows HP power supplies to be digitally controlled via
the Hewlett-Packard Interface Bus (HP-iB} from a calculator,
computer, or other controller.
The digital format is bit
parallel, byte serial, ASCII coded format.
The 59501B:
1-4
The 59501B. is basically a digital-to-analog (D/A)
converter that provides an output voltage in response to
digital data received on the HP-1B. Two programmable
output ranges (1V and 10V) are available.
In addition, a
switch on the rear panel allows selecting either a unipolar or
bipolar output mode.
The unipolar mode provides a Q to
.899V or a Oto 9.99V output range and the bipolar mode
provides a —1V to *0.998V or a —10V to +9.98V output
range.
The 59501B's output can be used as a programming
voltage for controlling a wide range of dc voltages and
currents from HP power supplies or as a source voltage for
testing electronic components such as integrated circuit
packages (C's).

Isolators within the 59501B protect other instru-
mentation on the HP-1B from damage that could be caused
by power supply outputs.
Also, an internal circuit ensures
that the output is held near zero until programmed data is
received.
Power supply programming is accomplished
through use of the 59501B's
programmable output voltage
and its front panel adjustments.
By making the appropriate
connections between the 59501B's
rear terminals and the
programming terminals on the supply, the output voltage
lor current, if available) of the power supply can be
programmed from zero to its full rated output.
The
59501B's
front pane! adjustments provide fast and easy cali-
bration of power supply outputs.
The ZERO ADJUST
4-1
enables the user to correct for small offsets in power supply
response to programmed inputs.. The POWER SUPPLY
FULL SCALE ADJUSTMENT
(COARSE and FINE)
allows the user to set the maximum output desired from the
power supply when the 59501B
is programmed to íts
maximum output.
This method of programming is called
voltage programming with gain. Power supply program-
ming is described in greater detail in Section 111.
is received.
Output current up to 10 milliamps is available.
and is automatically limited to protect the 59501B
and
the user equipment.

HP-IB CAPABILITIES
1-8
The 595018
has "listener" and "acceptor hand-
shake" HP-IB functional capabilities. The LISTENING
indicator on the front panel provides a convenient means of
monitoring the 59501B's operating status.
The
695018
does not have:
controller, talker, source handshake, service
request, device trigger, extended listener, extended talker,
parallel poli, and remote/local HP-IB functional capabilities. -
AH HP-IB functional capabilities are described in IEEE
Standard 488-1975.
