Information
The Com 3 is a lightweight, compact service monitor for
testing AM and FM transceivers. The internal battery, which
is a standard feature of the Com 3, combined with the
optional carrying case and low weight (13 lbs), make it
ideal for field use. Utilizing specially designed micro
powered oven circuits, warm -up time is minimal, providing
maximum use of the battery.
The frequency range is 100 KHz to 999.999 MHz in 500 Hz
steps. Standard CTS tones as well as a 1 KHz tone can be
generated. RF power is continuosly variable in five ranges
from 0.1 ¡iv to 10,000 ¡j.v. The display is a seven digit
LED type which will display frequencies generated or
received, CTS off air, as well as being an audio and RF
frequency counter. Deviation and frequency error are
displayed on a 20 segment LED bargraph, which is easily
visible from across the shop.
An internal RF relay switches transmitted power greater than
500 mW to a rear panel mounted BNC connector. This protects
the Com 3 from accidental keying and allows easy connection
of an antenna, power meter, or dummy load.
