be

assigned

a

bus

address.

Table

3-8

gives

the

allowable

address

switch

settings.

The

setting

of

switches

Ai

through

As

defines

the

addresses.

The

listen

address

{Table

3-8)

is

used

to

program

the

functions

of

the

5355A.

3-64.

Before

learning

the

programming

details

of

the

5355A,

some

knowledge

of

5345A

programming

is

required,

as

described

below.

3-65.

Programming

the

5355A/5345A

3-66.

The

5355A

is

programmed

for

remote

control

of

all

its

operating

modes

by

the

codes

shown

in

Table

3-9.

The

5355A

operates

remotely

only

in

the

listen

function

and

does

not

output

to

the

HP-IB.

3-67.

Measurement

data

from

the

5355A

is

sent

to

the

5345A

for

processing

and

display.

This

information

is

sent

to

the

HP-IB

via

the

talk

output

of

the

5345A

which

must

be

programmed

by

the

codes

shown

in

the

5345A

Operating

and

Service

Manual,

except

as

described

in

paragraph

3-68

below.

NOTE

5345A

are

invalid

when

the

5355A

is

plugged

in,

as

detailed

in

the

following

paragraph.

3-68.

Hold)

and

J1

(Sample

Trigger

Command)

are

invalid

when

the

5355A

is

plugged

into

the

5345A.

These

functions

are

performed

by

programming

the

5355A

plug-in

using

the

Hold

i.e.,

HD0

selects

the

5345A

Sample

Rate

and

HD1

is

used

in

place

of

the

normal

5345A

code

E9

for

Sample

Rate

Hold.

(Refer

to

Table
