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.
