Measurement Time
(voltage or current)
50 ms average
(includes the default time of 30 ms

for acquiring
data, and a 20 ms data processing overhead)
Command Processing
Time
4 ms average
(for output to begin to change
following receipt of digital data)
Remote Sense Capability
Up to 2 V can be dropped across each load lead.
(add 2 mV to the voltage load regulation
specification for each 1 V change in the positive
output lead due to load current change.)

INH/FLT Characteristics
Maximum ratings:
FLT Terminals:
INH Terminals:
16.5 Vdc between terminals 1 and 2; 3 and 4; and
from terminals 1 or 2 to chassis ground
Low-level output current = 1.25 mA max.
Low-level output voltage = 0.5 V max.
Low-level input voltage = 0.8 V max.
High-level input voltage = 2 V min.
Low-level input current = 1 mA
Pulse width = 100
µ
s min.
Time delay = 4 ms typical
1
For full scale current changes with a risetime of 20
µ
s, an additional 0.5% error exists in the first data point in the
buffer after the change. The error percentage increases proportionally with the decrease in risetime.
2
This time may be reduced by changing the default conditions of 2048 data points, however, measurement accuracy
will be reduced.
3
COMPatibility language is used to program the Agilent 663xA Series power supplies.
