Supplies
22 AGILENT SYSTEM dc POWER SUPPLIES
Multiple-Output: 40 W and 80 W
2, 3, or 4 independent isolated outputs
Dual-range linear outputs
Low ripple and noise
Fast up- and down-programming
Readback of output voltage and current
Current sourcing and sinking
6621A-6624A, 6627A
dc Floating Voltage: All outputs can be floated up to ±240 Vdc from
chassis ground
Remote Sensing: Up to 1 V drop per load lead. The drop in the load
leads is subtracted from the voltage available for the load.
Command Processing Time: 7 ms typical with front-panel
display disabled
Down Programming: Current sink limits are fixed approximately
10% higher than source limits for a given operating
voltage above 2.5 V
Input Power: 550 W max., 720 VA max.
GPIB Interface Capabilities: SH1, AH1, T6, L4, SR1, RL1,
PP1, DC1, DT0.
Regulatory Compliance: Listed to UL1244; conforms to IEC 61010-1;
carries the CE mark. See page 73 for more information
