Description
Information
                                    The Transalyzer is a precision in-line instrument designed
for usage with 50 ohm coaxial radio frequency systems. It
continuously monitors the output of a transmitter. In
adddition, the Transalyzer can be connected to a receiver
for the purpose of analyzing received stations. The Counter
Model Mark IIIA-C can be utilized to measure the transmitted
frequency , or the frequency of other equipment.

Transmitter monitoring includes the 160 through 10 meter
Amateur bands, and the 11 meter CB band. Both Amplitude
Modulated (AM) and Single Sideband Suppressed Currier (SSB)
signals can be analyzed.

Received monitoring of AM and SSB signals can be performed
for stations well above 30 KHz; the maximum frequency
depends upon the receiver.

There are two (or three) types of displays: a Wattmeter, an
Oscilloscope, and a Frequency Counter in the Mark IIIA-C.
The Wattmeter (transmitt only) indicates output power,
either peak or average, up to a maximum of 2000 watts. In
addition, the standing wave ratio (SWR) and associated
percent reflected power can be measured, Percent reflected
power is the percentage of forward (transmitted) power that
is being reflected back from the antenna.

The oscilloscope displays the percentage of modulation,
modulation distortion, hum or ripple in an AM or SSB signal
on transmit in conjunction with the two-tone oscillator. In
receive monitoring, the same things can be determined but
with n.ore difficulty unless the transmitting station
employs a tone oscillator.

A minimum of 2 and 1/2 watts (on Transmit) is required for
proper Transalyzer operation. A phone jack allows the
modulation in an AM transmitted signal to be heard through
earphones. (System will not function with SSB).

ADDITIONAL INFORMATION

Nearly all transmitters will modulate 100% negative
(centerline) very easily, out many will not modulate more
than 70 to 80% in the positive direction. An Af-:
transmitter should not be modulated beyone the point where
negative modulation goes to 100%, or the positive peaks are
flattened. A SSB transmitter, with two-tone oscillator input
should not be modulated beyone the point where positive
peaks start to flatten. Any transmitter will sound the
loudest and clearest when operated in this manner.
