•
Destination Address
—Enter the IP Address of the radio to ping
tested.
•
Count
—Enter the number of pings to send across the radio link.
•
Bytes
—Enter the number of bytes in each ping.
•
Interval
—Use this box to specify how long (in seconds) between
ping transmissions after a response is received.
•
Timeout
—Use this box to specify how long (in seconds) to wait for
a ping response before a timeout occurs.
RF Keying Test
The
RF Keying Test
screen provides a way to place the transmitter on the
air to check the measured RF power output, measure reflected power
from an antenna system, or to provide a signal at a receiving station so
that RSSI can be checked.
•
Key Radio
—Set to
ON
to enable the RF keying test;
OFF
to disable
it. The
Commit Configuration
button must be clicked to apply the set-
ting.
•
Measured RF Power
—Provides an indication (in dBm) of the mea-
sured power output of the transmitter.
Spectrum Graph
A unique feature of the transceiver is the ability to view the RF spectrum
above and below the operating frequency using its built-in Spectrum
Graph. Often, this can assist in diagnosing the cause of interference, or
to view other signals near your operating frequency.
To use the Spectrum Graph, you must first specify a
center frequency
and a
span frequency
. The
center frequency
is the frequency that you
wish the spectrum display to be centered on. The
span frequency
defines
the width of the overall spectrum to be examined.
•
Center Frequency
—The frequency (in MHz) that the graph will be
centered on.
•
Span Frequency
—Width (in kHz) of the spectrum to be examined.
