Bench Operation
Chapter 1 gives the dimensions of your mainframe. The mainframe has plastic feet that are shaped to ensure self-alignment
when stacked with other Agilent System II cabinets. The feet may be removed for rack mounting. Your mainframe must be
installed in a location that allows sufficient space at the sides and rear of the mainframe for adequate air circulation. Do not
block the vents at the sides and rear of the mainframe.
Rack Mounting
The mainframe can be mounted in a standard 19-inch rack panel or cabinet. Refer to Chapter 1 for mainframe dimensions.
A fully loaded mainframe can weigh over 36 kg (80 lbs). Install the mainframe into the rack before installing the modules
into the mainframe.
Rack mounting kits are available as option numbers 908 and 909 (with handles). Installation instructions are included with
each rack mounting kit.
Note Instrument support rails are also required for rack mounting. These are normally supplied with the
cabinet and are not included with the rack mounting kits.
Temperature Performance
The mainframe can operate within the temperature range of 0°to 55°C. Fans in each module cool the modules by drawing
in air through the sides of the mainframe and exhausting it out the back. Using Agilent rack mount or slide kits will not
impede the flow of air.

corresponds to the slot locations indicated on the mainframe.
The frame mode switch must be set to AUX (auxiliary) when the mainframe is serially-linked to another mainframe that is
directly connected to the GPIB. This also applies when the mainframe is serially linked to an Agilent 603xA/664xA/665xA/
667xA power supply that is directly connected to the GPIB.
In mainframes that have the frame mode switch set toAUX, modules are assigned secondary addresses of 8 to 15.
Secondary address 8 corresponds to slot location 0 on the mainframe and secondary address 15 corresponds to slot location
7 on the mainframe as shown in the following diagram.

Mainframe Slot Locations/Addresses
Mainframe Mode
Switch = MAIN Mainframe Mode Switch = AUX
Slot Location 0 1 2 3 4 5 6 7 0 1 2 3 4 5 6 7
Secondary Address 0 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15
Note Secondary addresses are reserved for the mainframe whether modules occupy the associated slot locations
or not.
You may want to apply stick-on labels over the slot locations of the mainframe to indicate that the modules installed in the
auxiliary mainframe are at secondary addresses 8 to 15. You may also label the modules according to their slot locations.
If any modules are removed, they can then be reinstalled in the same slot.
Figure 2-4 illustrates the relationship of the switch settings and secondary addresses. Refer to Chapter 3 for connection
information.

Module Installation
Note A fully loaded mainframe can weigh over 36 kg (80 lbs). Install the mainframe into the rack before
installing the modules into the mainframe.
All modules install through the front of the mainframe. Installation (and removal) can be accomplished even when the
mainframe is rack-mounted. To install the modules in the mainframe, refer to Figure 2-5 and proceed as follows:
■ Use a flat-bladed screwdriver and release the pull tab by pressing down.
■ Extend the pull tab from the module so that the serial number is visible.
■ Slide the module into the slot until it is fully inserted in the mainframe.
■ Push the pull tab into the front of the module. The slot number should be visible below the pull tab.
Note If the module is not fully inserted in the mainframe, the pull tab will not retract into the module.
■ Install filler panels in the front of any unused mainframe slots.
■ Install the module connectors on the back of the mainframe.
Note Instructions for wiring and installing module connectors are included with each module.

Module Removal
All modules are removed through the front of the mainframe. Modules may be removed even when the mainframe is turned
on.

■ There must be no or minimal current flowing through the connector pins at the back of the module
that is being removed. This can be accomplished by disabling the module. If this precaution is
repeatedly violated at high current, the connector pins at the back of the module
will be damaged.
■ There must be no activity on the GPIB bus, the trigger connectors, or the FLT/INH connector of
the mainframe when a module is removed. This can be accomplished by not generating any GPIB
or FLT/INH activity, and by setting all modules to the trigger idle state (refer to the module
Programming Guide). If this precaution is violated, GPIB commands to other modules may be
corrupted, trigger or FLT/INH data may be lost, or an inadvertent trigger may be generated in
another module.
To remove the module from the mainframe, proceed as follows:
■ Use a flat-bladed screwdriver and release the pull tab by pressing down (see Figure 2-5).
■ Grasp the pull tab and pull the module out of the mainframe.
Note The module connector remains attached to the mainframe after the module has been removed.
Mainframe Turn-On Checkout
The turn-on checkout procedures that verify module operation also verify the operation of the MPS mainframe. You cannot
verify the operation of the mainframe without having at least one installed module. The module self-test sequence checks
the following mainframe functions:
■ mainframe microprocessor
■ GPIB interface
■ module/mainframe communications link
Refer to the module User’s Guidefor complete information on the turn-on checkout procedure.
