ENERAL

 

INFORMATION

 

The

 

GFT9404

 

module

 

provides

 

four

 

independent

 

delay

 

channels

 

(T0

 

to

 

T3).

 

The

 

delay

 

resolution

 

is

 

1

 

ps,

 

and

 

trigger

‐

to

‐

channel

 

jitter

 

is

 

less

 

than

 

50

 

ps.

 

SMB

 

outputs

 

deliver

 

5

 

V,

 

2

 

ns

 

rise

 

time,

 

under

 

50

 Ω

.

 

Amplitude

 

and

 

width

 

are

 

adjustable

 

on

 

each

 

output

 

channel.

 

The

 

GFT9404

 

also

 

provides

 

four

 

auxiliary

 

delay

 

channels

 

available

 

on

 

the

 

front

 

panel

 

(AT0

 

to

 

AT3)

 

and/or

 

on

 

PXI

 

trigger

 

lines

 

(PXI

 

TRIG0

 

to

 

PXI

 

TRIG3).

 

The

 

delay

 

resolution

 

is

 

5

 

ns

 

(one

 

timebase

 

clock),

 

and

 

trigger

‐

to

‐

channel

 

jitter

 

is

 

100

 

ps.

   

One

 

input

 

trigger

 

(TRIG

 

IN),

 

PXI

 

STAR,

 

internal

 

frequency,

 

or

 

software

 

trigger

 

is

 

used

 

to

 

trigger

 

off

 

all

 

output

 

channels.

   

The

 

module

 

offers

 

two

 

operating

 

trigger

 

modes,

 

repetitive

 

or

 

single

 

shot.

 

The

 

control

 

panel

 

software

 

for

 

Windows

 

provides

 

a

 

simple

 

method

 

to

 

configure

 

settings

 

for

 

each

 

channel,

 

such

 

as

 

amplitude,

 

width,

 

trigger

 

source,

 

and

 

trigger

 

mode,

 

and

 

to

 

control

 

operation.

 

You

 

can

 

save

 

and

 

recall

 

settings.

 

The

 

software

 

allows

 

you

 

to

 

install

 

and

 

operate

 

multiple

 

GFT9404

 

boards

 

in

 

the

 

same

 

PXI

 

chassis.

 

The

 

module

 

serial

 

number

 

specifies

 

the

 

module

 

address.

 

The

 

GFT9404

 

is

 

the

 

ideal

 

instrument

 

to

 

provide

 

precisely

 

timed

 

pulses,

 

as

 

encountered

 

in

 

picosecond

 

laser

 

system

 

and

 

other

 

accelerator

 

applications.

 

 

Package

 

Contents

 

The

 

box

 

you

 

received

 

should

 

contain

 

the

 

following:

 

 GFT9404 

module, 

  CD containing the PDF user manual, LabVIEW driver, and GFT9404 application 

software, 

  Certificate of calibration.
