GENERAL OPERATION
In addition to the large vacuum fluorescent display, there are two
buttons on the front of the PM5K:
“Menu” and “Mode Select.”
These buttons are used to select the operational mode, and to
program the meter
’s several functions such as VSWR Alarm,
Power Monitor Alarm, Auto Ranging Scales, etc.
The following discussion shows you how to operate the meter. As
we add more features, you will be able to download more options
for your meter from the Palstar website. You will also find useful
information on the

of our partner company Array Solutions.

being delivered. It also keeps possible RFI causing cables away
from your transmitter, audio, data and CW circuits, therefore re-
ducing the chance of RFI and distortion to your signal.
A Power/VSWR meter that requires you to run coax to it since it
has no remote coupler means you have to mount the meter very
close to your operating position. Since you
’re routing your coaxial
cables through it, you are also bringing in possible RFI that can
affect your audio, CW tone, modulation, and also your PC. The
PM5K eliminates this possible source of RFI since the signals
passed to its display head are merely DC voltages from the re-
mote coupler.
The remote mounting capability is perfect for multiple transmitter
sites, remote power sensing for tuners, PA stages, broadcast tow-
ers, etc. The ability to have the meter report alarms via the relay
closures or the software makes it a very flexible instrument for re-
mote sites as well.
Remotely controlled radio applications over the internet should find
this meter readily adaptable with the PRO application software.
DIRECTIONAL COUPLER CONNECTORS
You may order the unit with SO239 (standard) connectors, Type-
N, or 7/16 Din.
The connectors are field replaceable if you should need to do so.
ACCURACY AND CALIBRATION
The PM5K resolves 12 equivalent bits of analog to digital data.
There are 8 sampling channels: 4 forward and 4 reverse. A cali-
bration table is generated for each meter that resides in the proc-
essor
’s non-volatile memory for each of these channels. This al-
lows the best accuracy possible over the auto ranging scales. This
results in a display that has 1024 steps for each auto ranging
scale.
Chose your bar graph scale so that it is the best choice of
resolution for the power your equipment is running. For
