Dual Channel 500MHz RF Meter:
Graphic CPU
Graphic CPU used in PM4 is a a core of
our "INFINITY" Project and is
developed keeping in mind that we use same CPU/LCD/Hardware for
various Purposes or Projects, saving a lot of money in
hardware.
This is important for
homebrewers because RF measurement some times, is only a one
time a month (or a year!) requirement in a Radio Room!!
PM4 is designed to work as a
standalone unit. A PC program may be available in future from Tony/I2TZK.
PM4 is a dual channel 500MHZ RF
Meter, designed in two parts, interconnected by a D9 Male to Male
Cable (usually supplied with Graphic LCD/CPU KIT):
1. Graphic CPU and
2. Sensor unit with 2 X AD8307
Log amplifiers
