Safety Precautions

The following safety precautions should be observed before using this product and any associated instrumentation. Although
some instruments and accessories would normally be used with non-hazardous voltages, there are situations where hazardous
conditions may be present.

This product is intended for use by qualified personnel who recognize shock hazards and are familiar with the safety precautions
required to avoid possible injury. Read and follow all installation, operation, and maintenance information carefully before using
the product. Refer to the manual for complete product specifications.

If the product is used in a manner not specified, the protection provided by the product may be impaired.

The types of product users are:

Responsible body is the in
ment is operated within its specifications and operating limits, and for ensuring that operators are adequately trained.

Operators use the product for its intended function. They must be trained in electrical safety procedures and proper use of the
instrument. They must be protected from electric shock and contact with hazardous live circuits.

Maintenance personnel perform
voltage or replacing consumable materials. Maintenance procedures are described in the manual. The procedures explicitly state
if the operator may perform them. Otherwise, they should be performed only by service personnel.

Service personnel are trained to work on live circuits, and perform safe installations and repairs of products. Only properly
trained service personnel may perform installation and service procedures.

Keithley products are designed for use with electrical signals that are rated Measurement Category I and Measurement Category
II, as described in the International Electrotechnical Commission (IEC) Standard IEC 60664. Most measurement, control, and
data I/O signals are Measurement Category I and must not be directly connected to mains voltage or to voltage sources with
high transient over-voltages. Measurement Category II connections require protection for high transient over-voltages often as­sociated with local AC mains connections. Assume all measuremen
Category I sources unless otherwise marked or described in the Manual.

Exercise extreme caution when a shock hazar
The American National Standards Institute (ANSI) states that a shock hazard exists when voltage levels greater than 30V RMS,

42.4V peak, or 60VDC are present. A good safety practice is to expect that hazardous voltage is present in any unknown

circuit before measuring.

Operators of this product must be protected from electric shock at all times. The responsible body must ensure that operators
are prevented access and/or insulated from every connection point. In some cases, connections must be exposed to potential
human contact. Product operators in these circumstances must be trained to protect themselves from the risk of electric shock.
If the circuit is capable of operating at or above 1000 volts, no conductive part of the circuit may be exposed.

Do not connect switching cards directly to unlimited power circuits. They are intended to be used with impedance limited sourc­es. NEVER connect switching cards direct
vices to limit fault current and voltage to the card.

Channel assignments

The Model 7002-HD uses five slot designations for control of all relays. To control
the appropriate relay, the slot number must be included with the channel number
when you specify a channel. The channel assignment is formatted as follows:

S!CH

where: S is the slot number

CH is the channel number

Examples:

1!1 = Slot 1, Channel 1

5!10 = Slot 5, Channel 10

NOTE The specific channel mapping will depend on the particular card

being used. Consult the card manual for details.

Card 1

Card 2

When a card is used in the Card 1 position of the Model 7002-HD, it will be con­trolled using slots 1 through 5.

When a card is used in the Card 2 position of the Model 7002-HD, it will be con­trolled using slots 6 through 10.

Close and Open channels

Press the CLOSE key to close the channels specified in the channel list. Pressing
the OPEN key will open the channels specified in the channel list. The OPEN ALL
key opens all channels, including any channels not included in the list.

NOTE A channel will remain closed until the OPEN ALL or OPEN key is

used. Channel status can be determined only via remote. See
Section 5.

Scan channels

Perform the following steps to scan the channels defined in the scan list.

Step 1. Configure the layers of the Trigger Model

Arm layer

Factory power-on defaults set Arm Spacing to Immediate and the Arm Count to 1.
For most scans, these settings do not need to be changed.

Scan layer

Factory power-on defaults set Scan Spacing to Immediate and the scan count to
Infinite. For most scans, Immediate arm spacing is appropriate and does not have
to be changed. Scan count specifies how many times you want a channel scan to
repeat. If you do not want the scan to continue indefinitely, change the scan count
as follows:

1. Press SCAN CONFIGURATION to display the CONFIGURE SCAN menu.

2. Place the cursor on SCAN CONTROL and press ENTER to display the
SCAN CONTROL menu.

3. Place the cursor on NUMBER OF SCANS and press ENTER to display the
NUMBER OF SCANS menu.

4. Place the cursor on ENTER SCAN COUNT and press ENTER to display
the currently selected scan count. Note that 0000 indicates that the scan
count is currently set to infinite.

5. Use the keypad to key in the desired scan count and press ENTER.

6. Use EXIT to back out of the menu structure.

Channel layer

Factory power-on defaults set Channel Spacing to Manual and the channel count
to the scan list length (number of channels in the scan list). For most scans, using

Return to Section 3 topics

3-8 Getting Started Model 7002-HD User’s Manual

the scan list length as the channel count is appropriate. With manual channel
spacing selected, the STEP key is used to manually control the scan.

Available channel spacing selections are summarized as follows:

TIMER – In general, a channel is scanned each time the programmed timer inter­val expires.

GPIB – In general, each bus trigger (GET or *TRG) selects the next channel in the
scan.

MANUAL – In general, each time the STEP key is pressed the next channel in the
scan is selected.

TRIGLINK – In general, each trigger received via the Trigger Link selects the next
channel in the scan.

IMMEDIATE – Channels will continue to scan immediately and not wait for any of
the previous channel spacing events.

HOLD – Holds operation in the channel layer and prevents channels from being
scanned.

Perform the following steps to change the channel spacing:

1. Press SCAN CONFIGURATION to display the CONFIGURE SCAN menu.

2. Place the cursor on CHAN CONTROL and press ENTER to display the
CHANNEL CONTROL menu.

3. Place the cursor on CHANNEL SPACING and press ENTER to select the
SELECT CHAN SPACING menu.

4. Place the cursor on the desired channel spacing selection and press
ENTER. Note that selecting the TIMER will require that a time interval be
entered.

5. Use EXIT to back out of the menu structure.

NOTE A typical method to control channel scanning is to use DELAY. A

delay can be set for each slot. This delay is invoked after each
channel of that slot is closed. By setting Channel Spacing for Im­mediate, the scan rate will, for the most part, be controlled by the
DELAY period.

Step 2. Starting the Scan

Assuming the instrument is in the idle state (ARM indicator on VFD off), a scan
will not start until the STEP key is pressed. This takes the instrument out of the
idle state (ARM indicator on). The scan will then proceed according to how it was
programmed in Step 1.

A scan can be aborted at any time by pressing the OPEN ALL key.

IEEE-488 operation summary

The following paragraphs discuss fundamental information concerning operation
over the IEEE-488 bus. More information on operating the instrument from over
the bus is contained in Section 5 of this manual.

Bus connections

Before using the instrument over the bus, you must connect the IEEE-488
connector on the rear panel of the instrument to the IEEE-488 connector of
your controller. Use a Keithley Model 7007 or similar IEEE-488 cable for this
connection.

Primary address

The primary address of the Model 7002-HD must agree with the primary address
you intend to specify in the controller’s programming language. The factory setting
for the primary address is 7, so if you intend to use that address, you need not
change it. However, the primary address can be set to any value between 0 and
30 by using the GPIB setup menu (ADDRESS selection) available with the MENU
key.

Channel assignments

Channel assignments used to program the mainframe are based on the switching
card type, basic channel designation, and the card location in which the card is
installed (Card 1 or Card 2).

Slot designations

When programming the Model 7002-HD, you must designate the slot depending
on the card location:

• Card 1 location: slots 1 through 5

• Card 2 location: slots 6 through 10

Channel numbers

Combining the slot number with the card channel number provides the CHANNEL
assignment for the mainframe. The slot and card channel are separated by an
exclamation point (!). For the following examples, “CHANNEL” refers to the pro­gramming channel assignment for the mainframe, while “Channel” refers to the

Channel list and scan list

The Model 7002-HD can perform two basic operations: it can close and open a list
of channels, and it can scan through a list of channels. The following paragraphs
explain how to enter channels for these operations. The basic operations are
explained in ”Closing and opening channels” on page 4-9 and ”Scan procedure”

on page 4-13.

Each operation has its own list. For basic close/open operation, channels are

tered into the channel list. For scan operation, channels are entered into the

Closing and opening channels

One of the basic operations of the Model 7002-HD is to close (or open) one or
more channels specified by the user. All the specified channels will either close or
open at the same time. An exception to this is when the Single Channel mode is
enabled. With Single Channel mode enabled, only the lowest numbered channel
in the lowest numbered slot will close.

NOTE A channel will remain closed until the OPEN ALL or OPEN key

is used. Channel status can be determined only via remote. See
Section 5.

Perform the following steps to close and open channels:

Step 1. Select the channel list.

The channel list must be selected in order to close channels. The SCAN LIST key
toggles between the scan list and the channel list. If the channel list is not cur­rently selected, press SCAN LIST. The following channel list prompt is displayed:

SELECT CHANNELS

Note that when the scan list is selected, pressing EXIT will also select the channel
list.

Step 2. Define channel list.

Enter channels into the channel list. The following example demonstrates proper
format:

SELECT CHANNELS 1!1, 4!1-4!10, M1,

The above channel list includes channel 1 of slot 1, channels 1 through 10 of slot
4, and whatever channels are contained in the channel pattern stored at memory
location 1 (M1).

Step 4. Close (or open) listed channels.

Perform the appropriate close/open operation as follows:

1. Press the CLOSE key to close the listed channels.

2. Press the OPEN key to open channels that are listed in the channel list.
Note that only the listed channels will open. Any closed channels that are
not included in the channel list will not be opened by OPEN. To open
unlisted channels, press OPEN ALL.

Idle

The instrument is considered to be in the idle state whenever it is not operating
within one of the layers of the Trigger Model. The front panel ARM indicator is off
when the instrument is in the idle state. While in the idle state, the instrument can­not perform a scan.

From the front panel, the Model 7002-HD is taken out of the idle state by pressing

e STEP key. When not in the idle state (ARM indicator on) the scanning function

th
is considered to be enabled.

A scan can be aborted at any time by pressing the OPEN ALL key. The Model

Arm layer

In general, the instrument requires an arm event to allow operation to proceed to the
next layer (scan layer). With Immediate arm spacing selected, operation immediately
proceeds to the next layer when the instrument is taken out of the idle state. RESET
and factory defaults set arm spacing to Immediate. With one of the other arm spac­ing events selected, the instrument waits until the appropriate event occurs.

Operation in the scan layer is similar to operation in the arm layer, except that

ing is controlled by scan events rather than arm events. A timer is available in

spac
this layer to control scan spacing. When Timer scan spacing is selected, operation
will immediately proceed into the channel layer on the initial pass through the scan
layer. Each additional scan (1 to 9999, or infinite) will not occur until the pro­grammed timer interval elapses
second to 99999.999 seconds.

The Source Bypass and Output Trigger function in the same manner as the

Channels will be scanned in the order the
pattern M1 will be treated as a single channel entry. When the channel pattern is
scanned, the closed channels in the pattern will close and remain closed for the
duration of the scan. A channel pattern is useful for supplying bias voltages in a
test system.

At the conclusion of a scan, the last channel in the list will

Channel patterns (STORE and RECALL)

A channel pattern is a pattern of open and closed channels that is stored in mem­ory. Up to 500 channel patterns can be stored in memory.

There are two methods to store a channel pattern. One method is to actually close
and o

pen the desired channels and then save that pattern into memory. The other
method is to define a list of channels and then save that channel list into memory.
The channels defined in the list will be the closed channels of the pattern. All the
unlisted channels will be open.

Storing channel patterns

Perform the following steps to store a channel list in memory:

1. Decide on the storage method you wish to use:

The Model 7002-HD has enhanced external triggering capabilities using the Trig­ger Link. The Trigger Link has six lines allowing up to six instruments to be con­trolled over this trigger bus.

Trigger Link connections

The 8-pin micro DIN sockets used for the Trigger Link are shown in Figure 4-4.
The two rear panel Trigger Link connectors are actually connected in parallel to

Trigger Link operation

In general, Trigger Link input triggers to the Model 7002-HD are used to control
scan operation. In order for the Model 7002-HD to respond to Trigger Link compat­ible triggers, the appropriate layers of the scan must be properly programmed. For

ample, if you want Trigger Link input triggers to control the channel scan pro-

ex
cess, you must program Channel Spacing for TRIGLINK trigger events. Typically,

Trigger Link output trigger from the Model 7002-HD would be used to trigger

a
another instrument to measure the currently selected channel.

There are two modes of operation for Trigger Link: asynchronous and
semi-synchronous. In the asynchronous mode, separate lines are used for input

utput triggers, and in semi-synchronous mode, the same line is used for both

and o
input and output triggers.

In general, external triggers can be used as events to control scan operation. In
order for the Model 7002-HD to respond to external triggers, the appropriate layers
of scan operation must be properly configured. ”Scan procedure” on page 4-13
explains how to program the three layers of the scan.

Asynchronous operation

The asynchronous mode uses separate lines for input and output triggers. For typ­ical asynchronous Trigger Link operation, the channel layer of the scan is config­ured with Channel Spacing set to TRIGLINK and Triggerlink Mode set to
Asynchro
Input and output triggers can be set to any of the six lines, but they cannot use the
same line. For example, if you select line #1 for input triggers, then output triggers
must use one of the other five lines (#2 through #6). During operation in the chan­nel layer, each Trigger Link input trigger will close a channel in the scan. After the
rela
output a Trigger Link trigger (typically to a DMM to make a measurement). The
channel layer is configured using the CONFIGURE SCAN menu (see ”Scan pro-

cedure” on page 4-13).

The scan layer and/or arm layer can also be programmed for TRIGGER LINK:

When using Trigger Link in these layers, you must also select input and output
lines as you did in the channel layer. Keep in mind that you can use the same lines
in the scan and arm layers that you selected in the channel layer.

CING is set to TRIGLINK, and ARM SPACING is set to TRIGLINK.

Semi-synchronous operation

In the semi-synchronous Trigger Link mode, all triggering (input and output) in the
test system is controlled by a single line. When the normally high (+5V) trigger line
is pulled low (0V), a trigger occurs on the negative-going edge. When the trigger
line is released, a trigger occurs on the positive-going edge (see Figure 4-7). The
advantage of this single line trigger is that as long as one of the instruments in the

e

m holds the line low, the trigger is suppressed. In other words, the trigger will

Introduction

This section contains basic information on using the Model 7002-HD over the
IEEE-488 bus.

Remote operations

IEEE-488 bus connections

The Model 7002-HD can be connected to the IEEE-488 bus through a cable
equipped with standard IEEE-488 connectors, an example is shown in Figure 5-1.
The connector can be stacked to allow a number of parallel connections to one

rument. Two screws are located on each connector to ensure that connections

inst
remain secure.

Figure 5-1

IEEE-488 connector

A typical connecting scheme for a multi-unit test system is shown in Figure 5-2.
Although any number of connectors could theoretically be stacked on one instru­ment, it is recommended that you stack no more than three connectors on any one
unit to a

Connect the Model 7002-HD to the IEEE-488 bus as follows:

1. Line up the cable connector with the connector located on the rear panel.
The connector is designed so that it will fit onl

y one way. Figure 5-3 shows

the location of the IEEE-488 connector on the instrument.

2. Tighten the screws securely, but do not overtighten them.

3. Add additional connectors from other instruments, as required.

4. Make certain that the other end of the cable is properly connected to the
controller.

e that the IEEE-488 bus is limited to a maximum of 15 devices, including the

co
ber of devices, whichever is less. Failure to obse

rve these limits may result in

erratic bus operation.

IEEE-488 status indicators

The REM (remote), TALK (talk), LSTN (listen), and SRQ (service request) annun­ciators show the present IEEE-488 status of the instrument. Each of these indica­tors is briefly described below.

line, as the instrument must be addressed to listen with REM true before the REM
indicator turns on. When the instrument is in remote, all front panel keys except for

Trigger model

The following information describes the operation process of the Model 7002-HD
over the IEEE-488 bus. The flowchart in Figure 5-4, which summarizes operation
over the bus, is called the Trigger Model. It is called the Trigger Model because

Idle and initiate

The instrument is considered to be in the idle state whenever it is not operating
within one of the layers of the Trigger Model. The front panel ARM indicator is off
when the instrument is in the idle state. While in the idle state, the instrument
cannot perform any scan functions. Over the bus, there are two SCPI commands
that can be used to take the instrument out of the idle state: :INITiate or
:INITiate:CONTinuous ON.

Arm layer1

NOTE For front panel operation, this layer is called the arm layer.

In general, the instrument requires an arm event to allow operation to proceed to the
next layer (Arm Layer 2). With the Immediate control source selected
(:ARM:SOURce IMMediate), operation immediately proceeds to the next layer when
the instrument is taken out of the idle state. The *RST and :SYSTem:PRESet com­mands also set the arm control source to Immediate. With one of the other control
sources selected, the instrument will wait until the appropriate event occurs.

Arm layer2

NOTE For front panel operation, this layer is called the scan layer.

In general, the instrument requires a scan event to allow operation to proceed to
the next layer (trigger layer). With the Immediate control source selected
(:ARM:LAYer2:SOURce IMMediate), operation immediately proceeds to the next
layer. The *RST and :SYSTem:PRESet commands also set the scan control
source to Immediate. With one of the other control sources selected, the instru­ment will wait until the appropriate event occurs.

Trigger layer

NOTE For front panel operation, this layer is called the channel layer.

In general, measure events control the channel scan rate. With the Immediate
control source selected (:TRIGger:SOURce IMMediate), operation immediately
proceeds to the Delay. The *RST command also sets the measure control source
to Immediate. With one of the other control sources selected, the instrument will
wait until the appropriate event occurs.
