Quick Setup - Array Solutions PowerMaster Series Manual

Quick Setup

If you are currently using a wattmeter in your setup, you have everything
you need for a test. If you are not using a wattmeter, then you will need
a suitable jumper to connect the Directional Coupler to your station.
Connect the Directional Coupler as follows:
Using RG-8, RG213, or RG-58 or other 50 ohm coaxial cables
SOURCE goes to your transmitter or linear amplifier (directly)
ANTENNA goes to your antenna (or tuner)
For the 3 or 10 KW HF PowerMaster, plug the ¼" connector into the
Directional Coupler and Display Enclosure. Supply 12V DC power by
connecting a standard 2.1 mm coaxial plug to the DC jack in the back of
the Display Enclosure. The center pin is "+" 12V DC.
The PowerMaster is protected against polarity reversals, but be careful
just the same. Apply 12-15 volt DC power. You should observe that the
Vacuum Fluorescent Display becomes active and the firmware version
number will be displayed for a few seconds, then the unit will display
the operational mode screen. You are now ready for a test.
Simply use your normal procedure to transmit. The PowerMaster will
give you an instant indication of your power and VSWR. If your
transmitter has an internal tuner, you might want to turn it off. The
internal tuner will cause a 50 ohm impedance to be presented to the
finals of your transmitter, thereby changing the characteristic impedance
present at the antenna jack on the transmitter. This will affect the
accuracy of the PowerMaster (just as it would any other measuring
device).
PowerMaster Series RF Wattmeter
If the PowerMaster is functioning with a display of your forward power
and VSWR number with a bar graph to indicate relative power, you may
now proceed to program it from the front panel buttons or the control
software.
If you are having other problems, refer to the Trouble Shooting
section of this manual.
