Options  A1-A5  International  Power  Cords
Instruments  are shipped with  the detachable power-cord option as ordered 
by  the  customer.  Descriptive  information  about  the  international  power- 
cord  options  is  provided  in  Section  2  “ Preparation  for  Use."  Order  power 
cords  only  by  option  number  and  description.  The  optional  power  cords 
available for the  2245A are  as follows:
Standard,  North  American  120 V,  60  Hz,  74 in. 
Option A1,  Universal  Euro 220 V,  50  Hz,  2.5  m 
Option A2,  UK 240 V,  50  Hz,  2.5  m 
Option A3,  Australian  240 V,  50  Hz,  2.5  m 
Option A4,  North  American 220 V,  50  Hz,  2.5 m 
Option A5,  Switzerland 220  V,  50  Hz,  2.5  m
Option  15
The  2245A  Option  15  oscilloscope  provides  two  additional  output  signals 
from the rear of the  instrument:  a Channel 2  output  signal and an A GATE 
output  signal.  The following paragraphs  give a more detailed  description  of 
both  of  these  outputs.  Specifications  and  Performance  Checks  are  inte
grated  into the  appropriate  sections  of this  manual.
CH  2  Signal Output—Connector located  on the  rear-panel provides an out
put signal that is a normalized representation of the  Channel 2  input signal. 
The output amplitude into a 1  M  f l   load is approximately 20 mV per division 
of input  signal.  Into  a  50  f l  load,  the  output  amplitude is  approximately  10 
mV per division of input  signal.
A GATE  Output—Connector located on the rear-panel  provides  a TTL and 
CMOS compatible,  positive-going  gate signal that is  HI  during the A Sweep 
and  LO when the A  Sweep is  not  running.
