(1) For determining dynamic impedance in voltage mode.
(2) Based on 0.5mA load effect in FAST mode.
(3) For determining dynamic impedance in current mode.
(4) Add suffix “DM” to specify dual 3

⁄ 2 digit LCD displays in place of analog meters.

(1) For I
o
>50A, load effect = 2mA typ., 5mA max. In slow mode, the output capacitor adds 0-6mA to current mode load effect.
(2) One terminal grounded so that common mode current does not flow through load or current-sense resistor.
(3) BW: 20Hz-10mHz. (4) For high voltage ATE 325-0.8M the maximum output ripple and noise is 10mV rms and 50mV p-p.
FEATURES
• User selectable fast or conventional modes
of operation. Use fast-mode for rapid
response to programmed instructions or for
quick response in current mode to load
changes.
• Voltage and current modes with full and
equal control over the output in both modes.
• Multi-terminal user port allows the ATE to
be configured by arranging the jumpers on
a mating plug, PC-12.
• Full zeroing and full-scale calibration for
both the voltage and current control
channels.
• Programmable overvoltage crowbar.
Can be manually set from the panel or
programmed with a 0-10V analog signal.
Optically isolated input-output to inter-
connect multiple power supplies.
• Uncommitted amplifiers to manipulate
arbitrary control signals into the required
0-10V needed to program ATE. Two
provided. Can be used for scaling and
summing.
• Digital control through SN-series IEEE-
488 interfaces.
• The variation of the ATE’s voltage and
current offsets as a function of source, time
and temperature are tabulated in the static
specifications table. These may be used to
calculate the output effect by the relationship:
∆E

= ±∆E
r
(R
f
/R
i
)±∆E
io
(1+R

)±∆I
io
(R

)
where R
f
is the feedback resistor, and R
i
is
the input resistor from the reference, E
r
.
The tabulated offsets, more particularly their
change as a function of source, time and
temperature, allow a user to calculate perfor-
mance of the uncommitted amplifier(s) with
user specified input and feedback compo-
nents. The formula for this is given above.
