CONTROLLING THE OUTPUT USING EXTERNAL (ANALOG) SIGNALS (REMOTE)
How do I control the mode using an external signal?
$
, highlight External Mode,
!
, highlight Enable,
$
, then
%
to apply
changes and exit. This setting is not saved for power-up (PAR. 3.4.2). Select mode by applying either logic 1 or open circuit for voltage, or
logic 0 or short circuit for current, to pin 2 referenced to pin 9 of the Analog I/O port (PAR. 3.4.2).
How do I use an analog voltage to control the output (main channel)?
$
, highlight Reference input,
!
, highlight External
then
$
, then
%
to apply changes and exit. This setting is not saved for power-up. Apply ±10V signal to pin 11 referenced to pin 4 of the
Analog I/O port to control active channel (voltage or current) (PAR. 3.4.3).
How do I use an analog voltage to control the protection channel?
$
, highlight Protection Limit,
!
, highlight External then
$
, then
%
to apply changes and exit (not saved for power-up). Apply +1V to +10V signal to the following pins referenced to pin 12 of the
Analog I/O port to control limit channel from 10% to full scale: –Current Protect: pin 5, +Current Protect: pin 13, –Voltage Protect: pin 6,
+Voltage Protect: pin 14 (PAR. 3.4.4).
How do I choose between local, digital and analog control of the output? The unit normally powers up in Local mode. Send-
ing a command via RS 232 or GPIB interfaces automatically puts the unit into Remote mode. Press
!
to restore Local mode. If an analog
voltage is controlling the output (see above), local control of the main channel is disabled and digital commands are not accepted.
How do I use the BOP as an amplifier? See above to control the main channel and/or protection channel using analog signals. The
nominal (inherent) voltage gain of each model is calculated by (G
NOM-V
) = E
Onom
/ E
REF
. and nominal (inherent) current gain is (G
NOM-I
) =
I
Onom
/ E
REF
where E
REF
= 10V (see PAR. 3.4.3.1).
How do I control the gain of the BOP when used as an amplifier?
$
, highlight Reference input,
!
, highlight ExtlRefLevl then
$
, then
%
to apply changes and exit (not saved for power-up). Apply ±10V signal to pin 11 referenced to pin 4 of the Analog I/O port.
Main channel setting (SET) determines gain (G) by G = SET/10 (PAR. 3.4.3.2).
CONTROLLING THE OUTPUT USING DIGITAL INTERFACE (REMOTE)
How do I use the GPIB interface to control the power supply?
%
,
!
to view current GPBI address. To change GPIB address,
highlight GPIB address,
!
, use keypad to enter new address then

to save for power-up (see PAR. 3.5.3.2).
How do I change between SCPI and CIIL Data Format?
%

, highlight
SCPI or CIIL then

to save for power-up. (PAR. 3.5.3.1.2)
How do I change the Device Clear from SCPI to MATE compliant?

FEATURES
How do I save the power supply settings for future use?
!
, highlight Empty location,
!
. The power supply settings (Mode,
type and values for Main Channel Reference and Protection, and output on/off) are displayed. To save a different setting than that dis-
played, highlight the parameter,
!
highlight the selection or enter value using keypad, then
$
.
%
to exit or
$
to save for power-up.
(PAR. 3.3.8)
How do I modify saved power supply settings for future use?
!
, highlight desired location,
!
. The power supply settings
(Mode, Main Channel Reference and value, Protection type and values and output on/off) are displayed. To change a setting, highlight the
parameter,
!
highlight the selection or enter value using keypad, then

to exit or
$
to save for power-up. (PAR. 3.3.8)
How do I recall previously saved power supply settings?
!
, highlight desired location.
