Space requirements
The amount of floor space required for your Agilent 4072/4073 tester can be quickly and accurately determined by
using the System Component Template and blank grid sheets provided in “Example of 4072/4073 tester layout”.
The template and grid sheets are scaled so that each square on the grid sheet represents 20 cm
×
20 cm = 400 cm
2
(approximately 0.43 ft
2
) of floor space.
From the system component template sheet of Figure 2-3, simply cut out the components included with your
system, then place the cutouts on the grid sheet of Figure 2-6 to determine the best layout for your 4072/4073 tester.
Keep the following points in mind when selecting the system location and performing the final site layout.
• Provide adequate space for the wafer prober. Position the wafer prober 1 meter (3.3 ft.) or less from the tester so
the signal cables can be connected from the system cabinet to the testhead. Table 2-1 shows the cable lengths
from the bottom of the system cabinet.
• Provide at least 0.6 meter (24 in) of clearance at the front and rear of the system cabinet to allow space for
servicing. Agilent Technologies recommends 1 meter (39 in) of space for servicing.
• Make sure there is adequate workspace around the system so that operating personnel can move freely, without
affecting system operation.
• To ensure adequate clearance for the system, check all doors, elevators, and passageways that the tester will use
on the way to the installation site. See Figure 2-1 for the dimensions of the system cabinet.
• If the system controller is to be rack mounted in the system cabinet, the distance between the system cabinet
and the display/keyboard/mouse must be 50 cm (20 in) or less. If you want to locate them farther than it,
prepare extension cables for video and USB. At this point, the USB extension cables must be in “Repeater
type”, not “HUB type”.
