Using the Mainframe

The Agilent E1401B mainframe is designed in full compliance with the
VXIbus specification (Rev. 1.4) and VMEbus system specification (Rev.
C.1). The mainframe contains 13 slots for plug-in modules and can be rack
mounted in either the forward or reverse position.
•
Improved Power Supply Reliability
•
Solid state automatic bus grant sensing to bypass empty slots.
•
Variable speed fan cooling.
•
Rear mounted 25-pin D connector for auxiliary power supply
monitoring.
•
Easy replacement of major components - most can be replaced from
the rear of the mainframe, even while the mainframe is mounted in a
rack.
•
Seven standard VXIbus power supply voltages - all overvoltage,
overcurrent, and temperature protected.
•
Maximum Usable Power (total power supply output power before
thermal protection shutdown): 900 W @25°C, 800W @ 40°C,
650 W @ 55°C.
The Agilent E1401B mainframe includes a power supply which
automatically adjusts for standard nominal line voltages of 100/120 VAC
and 220/240 VAC, and nominal power line frequencies of 50 Hz and 60 Hz.
The power supply has a power factor corrected input section and thus can be
powered from any nominal line input over the range of 100 VAC to 240
VAC. The power supply can also be powered from a 400 Hz AC line
frequency or DC power line voltages. Refer to Appendix A for complete
input power specifications.
Refer to "Agilent E1401B Safety Grounding Information" on
page 17 for complete grounding information when power line
frequencies exceed 66Hz.
