Agilent E3646A – 49A Dual Output
The new E3640A-series programmable dc power supplies are
60W/100W dual output dc power supplies with standard GPIB
& RS-232 interface. For general-purpose use, these programma-
ble power supplies offer the performance of system power sup-
plies at a surprisingly affordable price.
Clean and Stable Output
All models deliver clean and reliable power, dependable regula-
tion (0.01%) and fast transient response (<50usec to within
15mV). With 0.01% load and line regulation, Agilent E364xA
power supplies keep output steady when power line and load
changes occur. These linear supplies specify both normal mode
voltage noise and common mode current noise to assure less
interference with your DUT.
Standard remote interface
Standard GPIB and RS-232 interfaces, SCPI programming and
plug&play drivers for Agilent VEE and NI LabView make it easy
to program and integrate into automated test systems. You can
monitor the output terminals for voltage and current, and a query
command lets you read the programmed voltage and current.
Versatile Power
Agilent E364xA power supplies give you the flexibility to select
from dual output ranges. Both front and rear output terminals
are standard, and output load is protected against over-voltage
protection function. Remote sense is available to eliminate the
errors due to voltage drops on the load leads. New front panel
binding posts offer flexibility to use safety test leads, banana
plugs or stripped wires. Store and recall key enables you to save
and recall up to 5 frequently used operating states. For dual out-
put models, two outputs are electrically isolated to each other
and allows voltage tracking.

E3648A, E3649A: 9.5 kg (20.9 lbs)
dc Floating Voltage: Output terminals can be floated up to
±240 Vdc from chassis ground.
Remote Sensing: Up to 1V can be dropped in each load
lead. The drop in the load leads subtracts from the
voltage available for the load.
Settling Time: Less than 90msec for the output voltage to
change from 1% to 99% or vice versa following the
receipt of VOLTage or APPLy command via direct
GPIB or RS-232 interface.
Product Regulation: Designed to comply with UL3111-1; certi-
fied to CSA 22.2 No. 1010.1; conforms to IEC 61010-1;
complies with EMC directive 89/336/EEC(Group1, Class A)
OVP accuracy: 0.5% + 0.5 V, activation time: ≥ 3 V,
<1.5 ms, and <3 V, <10 ms
