LINE FUSE

The line fuse is located by the ac line receptacle. Check the
rating of the line fuse and replace it with the correct fuse if
necessary as indicated below. These are slow-blow fuses.
AC INPUT
0EM: 115 Vac ± 10%, 47-63 Hz, 200 VA, 130 W
0E9: 100 Vac ± 10%, 47-63 Hz, 200 VA, 130 W
0E3: 230 Vac ± 10%, 47-63 Hz, 200 VA, 130 W
DC OUTPUT
Voltage span over which output may be varied using front
panel controls.
Output V1: 0 to 25 V at 1 A
Output V2: 0 to 25 V at 1 A
LOAD REGULATION
Less than 0.01% plus 2 mV for a full load to no load change in
output current.
LINE REGULATION
Less than 0.01% plus 2 mV for any line voltage change within
rating.
RIPPLE AND NOISE
Normal Mode Voltage: Less than 0.35 mV rms/1.5 mV p-p
(20 Hz-20 MHz).
Common Mode Current (CMI): Less than 1 μA rms for all
outputs (20 Hz-20 kHz).
OPERATING TEMPERATURE RANGE
o
0 to 40 C for full rated output. At higher temperatures,
output current is derated linearly to 50% at 55
temperature.
TEMPERATURE COEFFICIENT
Less than 0.02% plus 1 mV voltage change per
operating range from 0 to 40

INSTALLATION

INITIAL INSPECTION

Before shipment, this instrument was inspected and found to
be free of mechanical and electrical defects. As soon as the
instrument is unpacked, inspect for any damage that may
have occurred in transit. Save all packing materials until the
inspection is completed. If damage is found, a claim should
be filed with the carrier. The Agilent Technologies Sales and
Service office should be notified as soon as possible.

Mechanical Check

This check should confirm that there are no broken knobs or
connectors, that the cabinet and panel surfaces are free of dents
and scratches, and that the meter is not scratched or cracked.

STABILITY (OUTPUT DRIFT)
Less than 0.1% plus 5 mV (dc to 20 Hz) during 8 hours at
constant line, load and ambient after an initial warm-up time
of 30 minutes.
LOAD TRANSIENT RESPONSE TIME
Less than 50 μsec for output recovery to within 15 mV of
nominal output voltage following a load change from full
load to half load, or vice versa.
OUTPUT VOLTAGE OVERSHOOT
During turn-on or turn-off of ac power, output plus overshoot
will not exceed 1 V if the output control is set for less than 1 V.
If the control is set for 1 V or higher, there is no overshoot.

Electrical Check

This instrument should be checked against electrical specifi-
cations. Perform the TURN-ON CHECKOUT PROCEDURE
in the following paragraph to confirm that the supply is
operational. Alternately, check the supply more fully using the
PERFORMANCE TEST in the service information section.

INSTALLATION DATA

The instrument is shipped ready for bench operation. Before
applying power to the supply, please read the INPUT
POWER REQUIREMENTS paragraph.

Location and Cooling

This instrument is air cooled. Sufficient space should be allowed
so that a free flow of cooling air can reach the sides and rear of
the instrument when it is in operation. It should be used in an
area where the ambient temperature does not exceed 40
