YELLOW FROG POWER METER MEASUREMENT
The Yellow Frog power meter is a wide range (800 to 2200 MHz), .5 db accurate, battery
powered RF power meter with LCD display. It can be used “stand alone” or in conjunction with a
PC. When connected to a PC using its built in USB port, the Yellow Frog displays both dBm and
Watts on the PC screen, this output can be saved to a disk file for use with programs such as
Microsoft Excel. The PC software required to interface to the Yellow Frog is supplied with the unit.
While the Yellow Frog is connected via the USB interface, it is fully powered by the PC (through
the USB cable).
Yellow Frog continually measures the RF at its input and reports the results on its built in
LCD display. Either dBm, Watts or both can be displayed. When displaying both, dBm and Watts
are alternated every 4 seconds. LED’s on the Yellow Frog display panel indicate the quantity being
displayed (dBm or Watts). At the same time, the Yellow Frog outputs the data measured via the
built in USB interface 4 times per second.
As supplied, the Yellow Frog is ready to be turned and measure RF power. For the best
accuracy over frequency, the Yellow Frog must be “told” what frequency is being measured. To
do this the Yellow Frog must be connected to a PC via the USB port. Once settings are made, the
Yellow Frog “remembers” them so that the PC is only required whenever some parameter needs
to be changed OR if it is desired to save measurement data to a disk file. The PC is also used to
set the Yellow Frog display mode (dBm, Watts or both). As supplied from the factory, the Yellow
Frog is set to the middle frequency (1500 MHz in most cases) and to display both dBm and Watts.
YELLOW FROG PC SOFTWARE
When the Yellow Frog is first connected to a PC via the USB interface, a driver must be
loaded (see appendix A). After the driver is loaded, the PC software can be run if it too has been
installed (see appendix A). With the Yellow Frog connected to the PC, locate the icon in Figure 1
and double click it. The PC will display the screen in Figure 2.
Figure 1

Figure 2
Note that the status bar indicates that the PC is requesting Unit Data from the Yellow Frog.
This data is required in order for the PC software to properly communicate with the Yellow Frog.
Wait until the Toolbar “Unit Data” indicator turns green, as shown in Figure 3.
MAIN YELLOW FROG SCREEN
The display contains 4 components:
dBm meter – indicates the current Yellow Frog measured RF power in dBm in a voltmeter display
and in text below the meter.
Watt meter – indicates the current Yellow Frog measured RF power in Watts in a voltmeter display
and in text below the meter.
Yellow Frog internal temperature in degrees Centigrade. If the Yellow Frog gets too hot, a warning
is displayed.

Hopping Frogs are displayed below the meters and “hop” each time data is received from the
Yellow Frog.
Figure 3
The Tool bar contains buttons and indicators used to control the Yellow Frog. The screen between
the tool bar and status bar displays the real time data received from the Yellow Frog. The Watt
meter scale can be changed by double left clicking on it while the mouse pointer in on the Watt
meter. The frogs above the status bar and the “spinner” in the status bar change whenever data is
received by the PC.
MAIN SCREEN WITH INPUT OVERLOAD

The following screen is displayed if the RF power being measured by Yellow Frog is too high. The
Yellow Frog LCD displays “----“ in this condition. Do not run the Yellow Frog for prolonged
periods of time in this condition.
MAIN SCREEN WITH FROG BATTERY LOW
6
If the Yellow Frog’s internal battery is low, the PC displays the following screen. The Yellow Frog
LCD also shows “lo bat”. Since the Yellow Frog is powered by the PC USB, this condition is a
warning, but does not cause a degradation of the data received. When the Yellow Frog is detached
from the USB, however, the batteries should be changed.
