REAR INTERFACE INFORMATION
Functions Available at Rear Connector
Slots exist between pins 23 , 24 , and 6 , 7 on the Sine
Shaper board and pin 6 , 7 on the Output Amplifier board .
The slot between pins 6 and 7 identifies the FG 5010 as a
member of the TM 5000 family . Insert a barrier between
pins 23 and 24 of the power module jack the Sine Shaper
board plugs into to prevent noncompatible plug - ins from be
ing
inserted in slots wired
for the FG
5010. This
protects
the
plug - in if
specialized
connections
are
made to
that
compart
ment . Consult the power module manual for further informa
tion . Signal inputs , outputs , or other specialized connections
may be made to the rear interface connectors as shown in
the input - output assignments illustration ( Fig . 7-10 ) . These
connections are not factory wired . A wire kit , Tektronix Part
No. 020-0701-00 , provides the wires and instructions for
making the necessary connections .

Output
board
assignments and

GPIB
connections .
Making
Connections
Disassemble the
instrument to gain
access
to the
front of
the
Interconnect board .
Disconnect
the
cables from
the front
panel bnc connectors to the Interconnect board . See the
adjustment
location
illustrations in the
pullout
pages
at
the
rear of
this
manual for the
location
of
signal
inputs
and
out
puts on the
Interconnect
and
Sine Shaper boards
. The cable
connecting J1812 , on the Interconnect board , to the front
panel TRIG OUTPUT connector may be left connected . Ei
ther the
trigger output
or
trigger
complement
output
may be
routed to the
front
panel through
J1015 on
the
Sine
Shaper
board . The
other output may be
routed to the
rear
interface
output . These
outputs may be
used
simultaneously .
Use
of
the
rear interface
inputs and
outputs
causes
some
degratation in signal performance .
A lead is provided to bring out to the rear interface a
signal that
remains
high
during the
time the loop
clamp is
disabled .
For
N
BURST ,
this
time
is
roughly
equivalent
( de
pending on frequency ) to the length of the burst , less the
last half
of the
last
cycle
.
To
connect this
wire ,
remove the
shield on the
Loop 1
board
located over J1210 as
shown
in
the
adjustment
location
illustration
located
in
the
pullout
pages in the rear of this manual . Run this wire through the
hole
in
the
shield
over
J1210 ,
forward
across the
edge
con
nectors
on
the
Interconnect
board
, and
back along the
out
side of
the
Sine
Shaper
board to
the single
pin
spare
connector
as
shown in the
adjustment
location illustration .
After all
connections
are made ,
reinstall the
boards .
Maintenance - FG 5010
A description of the rear interface connections follows .
Aux
Output (
28A
)
This is the rear interface output connection . It is not fac
tory connected . Make connections as previously described .
Aux Output Common ( 27A )
This is the
return
connection for the
Aux
Output
.
Aux
Trig Output (
27B )
This
is
the
rear
interface
trigger
output . It is
not
factory
connected
.
The signal is
+2 V from 50
. This
signal can be
either the
trigger output or
trigger
complement
output
( 180 °
phase difference ) depending on the cable connection . Both
signals can be
used
simultaneously ; one
signal at the
rear
interface and
the
other at the
front
panel
. See
the
adjust
ment
location illustration for the
Sine
Shaper board .
Aux Trig Output Common ( 28B )
This
is
the
return
circuit for
the
rear
interface
trigger
output .
Spare ( 25A )
This pin
connects
to
a
square pin on
the sine
shaper
board . See the adjustment location illustration for location of
this pin .
This pin
may be
used
for a
burst
-
timed
signal output
as previously described under Making Connections . Return
circuit for
this
signal is
chassis
ground
.
Aux
Trig
/
Gate
Input (
24B )
This signal is not factory wired . A jumper to select the
input impedance for this connection is located on the Loop 2
board
.
See the
adjustment
location
illustration
for
jumper
location . Input impedance is either 50 or 1 Mº . Maximum
input
is
± 5
V.
Aux Trig / Gate
In
Common
(
25B )
This
is
the
return
path
for
the
Aux
Trig
/
Gate
In .
Aux
AM
Input
(
23A )
This
connection is not
factory
wired .
Make
connections
as previously described . The input impedance is 10 km .
