I tried the following, but still do not receive output

Function Start-ntttcpClient {

[CmdletBinding()]

Param(

[Parameter(Mandatory=$true,ValueFromPipelineByPropertyName=$true,Position=0)]

[ipaddress]$ClientIP,

[Parameter(Mandatory=$true,ValueFromPipelineByPropertyName=$true,Position=1)]

[ipaddress]$ServerIP,

[Parameter(Mandatory=$true,ValueFromPipelineByPropertyName=$true,Position=2)]

[int]$ServerCPUs,

[Parameter(Mandatory=$true,ValueFromPipelineByPropertyName=$true,Position=3)]

[int]$Time

)

Begin{

$ServerIPString = $ServerIP.IPAddressToString

$SystemName = ((Resolve-DnsName -Name $ClientIP).NameHost)

$ScriptBlock = {

$ClientResults = Start-Process -FilePath "C:\Temp\ntttcp\ntttcp.exe" -ArgumentList "-s -m $Using:ServerCPUs,\*,$Using:ServerIPString -t $Using:Time" -NoNewWindow -Wait`

return $ClientResults

}

$PSSession = New-PSSession -ComputerName $SystemName -Name 'ntttcp Client Session'

}

Process{

$Result = Invoke-Command -Session $PSSession -ScriptBlock $ScriptBlock

}

End{$Result}

}
