OPTIONS

INTRODUCTION

This  part  contains  a  general  description  of  instrument  options  available  at  the  time  of  publication  of  this  manual.  Addi­

tional  information  about instrument  options  and option  availability can  be obtained either by consulting the  current Tektronix 
Product  Catalog or by contacting  your  local Tektronix  Field Office or representative.

POWER  CORD  OPTIONS

Instruments  are  shipped  with  the  detachable  power-cord  configuration  ordered  by  the  customer.  Descriptive  information 

about the  international  power-cord  options  is  provided  in  “ Preparation  for  Use”  in  Section  2.  The following  list  identifies  the 

Tektronix  part numbers for the  available  power cords.

Standard (United  States)

Option  A3 (Australian)

161-0104-05

Option A1  (Universal  Euro)

161-0104-06

Option A4 (North American)

161-0104-08

Option A2 (United  Kingdom)

161-0104-07

Option A5 (Switzerland)

OPTION  33

Option  33,  the  Travel  Line  option,  provides  impact  protection  needed  for  rough  industrial  and  service  environments. 

When  the  instrument  is  ordered  with  Option  33,  the  instrument  comes  equipped  with  the  Accessory  Pouch  and  the  Front 
Panel  Cover,  front  and  rear  mounted  shock  absorbing  rubber  guards,  an  easy-to-use  power  cord  wrap,  and  a  carrying 
strap.

OPTION  10  AND  OPTION  12

INTRODUCTION

Option  10  provides  a  communications  interface  and 

additional  memory  for  the  instrument.  The  interface  imple­
mented  conforms  to  the  specifications  contained  in  IEEE 
Standard  Digital  Interface  for  Programmable  Instrumenta­

tion  (ANSI/IEEE  Std  488-1978),  commonly  referred  to  as 
the  General  Purpose  Interface  Bus  (GPIB).  It also complies

with  a  Tektronix  Standard  relating  to  GPIB  Codes,  For­
mats,  Conventions  and  Features.

Option  12  provides  a  communications  interface  and 

additional  memory  for  the  instrument.  The  interface  imple­
mented  conforms  to  RS-232-C  specifications.  It  also  com­
plies  with  a  subset  of the Tektronix  Codes,  Formats,  Con­
ventions  and  Features  standard.
