Mainframe Description

A mainframe is a device into which plug-in modules may be installed to create an instrument

in the modular measurement system. The HP 70001A mainframe provides the structural

environment for plug-in instrument modules along with cooling, power, and digital

communication interface buses.

It can accommodate 1/8-, 1/4-, 3/8-, and 1/2-width modules, and has a maximum capacity of

eight 1/8-width modules.

Standard rack compatibility is provided, and bench-top use is facilitated with integral bails and

retracting handles.

The Hewlett-Packard Modular System Interface Bus (MSIB) supports high-speed digital

communication among instrument modules within a mainframe and among instruments

connected to the external MSIB loop.

Every module in a mainframe has access to the standard Hewlett-Packard Interface Bus

(HP-IB). This bus provides a path of communication among controllers, other HP-IB instruments

and individual modules.

The ac power input is switchable between several ranges.

Rear-Panel Features

Inputs/Outputs

Two MSIB Input/Output connectors and one HP-IB connector are located on the rear panel.

Each module can have an interface to the MSIB bus and to the HP-IB bus.

Hewlett-Packard Interface Bus (HP-IB).

The HP-IB connector provides feedthrough

communication among controllers, other HP-IB instruments, and with each module installed in

the mainframe.

Hewlett-Packard Modular System Interface Bus (MSIB).

The MSIB is the high-speed digital

bus used by master, slave modules and other elements for exchanging control information and

data. It consists of both an internal and an external bus. The internal bus is housed in the HP

70001A Mainframe and connects to each installed module within the mainframe. External

MSIB cables connect mainframes to each other, to the Graphics Display, and to other MSIB

compatible devices. This external MSIB bus allows multiple instruments to communicate and

be displayed simultaneously. The use of longer MSIB cables allows you to locate a display some

distance from the rest of the instrument. See \Remote Operation" in Chapter 2, \Installation."

Electrostatic Discharge Information

Electrostatic discharge (ESD) can damage or destroy electronic components. All work on

electronic assemblies should be performed at a static-safe work station. Figure 1-2 shows an

example of a static-safe work station using two types of ESD protection: (1) wrist-strap (with

greater than 1m isolation to ground) and table-mat combination, (2) heel-strap (with greater

than 1m isolation to ground) and conductive oor-mat combination. The two types must

be used together to ensure adequate ESD protection. Isolation to ground must be provided

for personnel protection. Refer to Table 1-3 for a list of static-safe accessories and their part

numbers.

WARNING

In order to provide proper personnel protection, the wrist- and

heel-straps must have greater than 1mohm isolation to ground.

a. Wrap the instrument in anti-static plastic to reduce the possibility of damage caused by

ESD.

b. For instruments that weigh less than 54 kg (120 lb), use a double-walled, corrugated

cardboard carton of 159 kg (350 lb) test strength.

c. The carton must be large enough to allow three to four inches on all sides of the

instrument for packing material and strong enough to accommodate the weight of the

instrument.

d. Surround the equipment with three to four inches of packing material, to protect the

instrument and prevent it from moving in the carton.

e. If packing foam is not available, the best alternative is S.D.-240 Air Cap from Sealed Air

Corporation (Commerce, California 90001). Air Cap looks like a plastic sheet lled with

1-1/4 inch air bubbles.

f. Use the pink (anti-static) Air Cap to reduce static electricity. Wrapping the instrument

several times in this material will protect the instrument and prevent it from moving in

the carton.

3. Seal the carton with strong nylon adhesive tape.

4. Mark the carton `FRAGILE, HANDLE WITH CARE'.

5. Retain copies of all shipping papers.

Installation

This chapter contains information needed to prepare a mainframe for use, and describes how

instrument modules are installed to congure the HP 70001A Mainframe into an HP 70000

Series system.

The information presented is general in nature.For more detailed information on conguration

and HP-MSIB addressing, refer to the installation and verication manual for the system master

(e.g., HP 70900A Local Oscillator).

The HP 70001A mainframe is a rugged structure into which modules of various widths

can be placed. It provides power, cooling, and a suitable environment for electromagnetic

compatibility for the modules, and manages all digital communications among the system

elements. LED fault indicators, on the lower front-panel, report mainframe or module

Preparation for Use

Line Voltage Selector

Set the line voltage selector to the setting corresponding to the power source used. Access to

this switch is provided through a hole in the left-front bottom cover. Refer to Figure 2-1 for an

illustration of the line voltage selector.

WARNING

CAUTION

Before turning this instrument on, make sure it is grounded through the

protective conductor of the ac power cable to a socket outlet provided

with protective earth contact. Any interruption of the protective

(grounding) conductor inside or outside the instrument, or disconnection

of the protective earth terminal, can result in personal injury.

Before turning this instrument on, make sure the line voltage selector is set to

the voltage of the ac power source.

400 Hz Option

The HP 70001A Mainframe is available with an option that allows it to operate on a power-line

frequency of 400 Hz. The 400 Hz option comes with an external in-line 600 V-A isolation

transformer that must be used when the instrument uses a 400 Hz power source.

WARNING

Never operate a 400 Hz option instrument on a 400 Hz power line without

using the in-line isolation transformer supplied for this purpose.Failure

to follow this precaution can create a shock hazard which may result in

personal injury.

The in-line isolation transformer must be removed from the 400 Hz option for 50/60 Hz power

source operation. Failure to remove the in-line 400 Hz transformer will result in the 400 Hz

transformer input fuse. When the isolation transformer is removed, a standard power cord

must be used. The in-line transformer must be reinstalled when using a 400 Hz power source,

in order to protect the user from electric shock hazard.

Cabling

The HP-MSIB cables are connected in a serial (daisy-chain) manner, coupling the input of one

element to the output of next until the loop is completed.

Remote Operation

The use of long HP-MSIB cables to separate the mainframe and display, or other products

supporting HP-MSIB, allows remote operation. Since the signals on the HP-MSIB are digital,

only measurement speed is slightly degraded.

Addressing

The HP 70001A Mainframe does not have an HP-MSIB address. The mainframe acts as an

HP-MSIB arbitrator, allocating time on the HP-MSIB bus to any module or device designed to

work with an HP 70000 Series system that requests it.

Adjustments

The HP 70001A Mainframe has only internal service-related adjustments. These adjustments

Verication

This chapter normally contains unit performance-verication tests, which evaluate the

electrical performance of the unit against its specications. There are no performance-

verication tests that apply to the HP 70001A mainframe specications.

Power-On Self-Test

The act of turning on an HP 70000 Series system causes any modules installed in the system to

execute a power-on self-test. The mainframe is not involved in these tests except in supplying

power and communication for the modules.

Fault Indicators

The HP 70001A has three fault indicators. While these indicators are located in the mainframe,

problems external to the mainframe can cause the indicators to turn on. External problems

should be investigated before troubleshooting the mainframe.

Excessive ambient temperature, exceeding 55C will cause the

the mainframe to a cooler environment and wait for the

temperature to decrease to the normal operation range.1When

the temperature decreases the mainframe will restart itself.

If the indicator goes out after the mainframe has cooled the

mainframe is probably not at fault.

If the problem persists; when the mainframe attempts to restart

itself, verify that both cooling fans are operating by checking

the airow into both of the rear-panel fan-intake openings of

These two conditions will also cause the the VOLT/TEMP fault

indicator to come on and the instrument will latch in a fault

condition. The mainframe is in need of internal repair or

adjustment. It will shut down and not attempt to restart until

ac line power is cycled.

CURRENT This circuitry senses and indicates if the load on the mainframe power supply

is too high. Upon sensing an over-current condition, the power supply is shut

down and latched. It will not attempt to restart until ac line power is cycled.

If a CURRENT fault indicator is on, check for a faulty module before

attempting to repair the mainframe. The following steps will help isolate the

I/O This circuitry senses the readiness of the external HP-MSIB. If the indicator is

on, HP-MSIB communications are inhibited. The I/O fault indicator light will be

on if one of the following conditions is true.

The external HP-MSIB loop is not complete. Check that both ends of all

HP-MSIB cables are securely connected.

2

Not all the elements on the external HP-MSIB loop have the power

turned on. Verify that the power is on to all mainframes and stand-alone

instruments on the external HP-MSIB.

The mainframe is in need of repair.

HP-MSIB communication will resume as soon as the problem is corrected.

If an I/O light fault is indicated, the following steps will help isolate the

problem.

Disconnect both HP-MSIB cables from the mainframe at the mainframe

connectors. Is the I/O fault indicator still on?
