SINAD Meter
SINAD (Signal to Noise And Distortion is a measure of signal degradation by unwanted or extraneous signals including
noise and distortion. The higher the figure for SINAD, the better the quality of the received signal. The SINAD figure is
expressed in decibels (dB) and is determined by the formula:
SINAD = 10Log (SND/ND)
Where:
SND = combined Signal + Noise + Distortion power level
ND = combined Noise+ Distortion power level
0db ≤ SINAD < 50 dB
The receiver must be fed a 1 kHz tone.
– Click Start Meter to start the SINAD meter. The calculated SINAD value is displayed.
– Click Refresh Meter to refresh the SINAD value calculated by the Meter.
– Click Stop Meter to stop the SINAD meter.
Ping Test
The PING command is a network tool used to test whether a particular host is reachable on the IP network. It works by
sending an ICMP (Internet Control Message Protocol) packet (echo request) to a target host and listening for the ICMP
echo response. Ping estimates the round-trip time (in milliseconds) and records any packet loss.
Enter IP Address
Enter an IP address in dot-decimal format of the unit to ping. For example, 192.168.205.100.
Execute Ping — Once you have entered an IP address to for the Ping command, click Execute Ping to execute the Ping
command. Allow enough time (20 seconds) to handle slow or non responding targets.
Command Response
If the Ping command executed above was successful, the response times appear in the text box when complete.
