multi-threaded ping

I was given this script by a vendor to run on some of my servers.  I get some exceptions when I run it

Exception calling "Send" with "2" argument(s): "An exception occurred during a Ping request."
    + CategoryInfo          : NotSpecified: (:) [], MethodInvocationException
    + FullyQualifiedErrorId : PingException
    + PSComputerName        : localhost

Can someone tell me how to write the below with Test-Connection instead of System.Net.NetworkInformation.Ping.  Here is the script

Function Test-Ping {
$parallelCount = $args[0] #Thread Count
$serverName  =$args[1]
$loop = $args[2]
$wait = $args[3]
$jobs = (1..$parallelCount) | % {start-job {
                $p = New-Object System.Net.NetworkInformation.Ping
                $serverName = $args[0]
                $wait = $args[2]
                (1..$args[1]) | % { $p.send($serverName, 10000); start-sleep -s $wait }
} -ArgumentList $serverName,$loop,$wait}
$jobs | wait-job
$jobs | receive-job
}
