Represents a PnP device property consisting of an array of real64 elements.
Methods
Win32_PnPDevicePropertyReal64Array has no methods.
Properties
Win32_PnPDevicePropertyReal64Array returns 5 properties:
'Data','DeviceID','Key','KeyName','Type'
Unless explicitly marked as writeable, all properties are read-only.
Data
The property value.
DeviceID
Identifies the PnP device.
Key
The value of the Key Name-Value pair that identifies the Data property.
KeyName
The name of the Key Name-Value pair that identifies the Data property.
Type
The type of the Data property.
Type returns a numeric value. To translate it into a meaningful text, use any of the following approaches:

"Name" defines the name of the property (in this example, it is "Type", but you can rename it to anything else)
"Expression" defines a scriptblock that calculates the content of this property
in this example, the scriptblock uses the hashtable defined earlier to translate each numeric
value to its friendly text counterpart:

# ...or dump content of property Type:

there is just one instance to work with.

this example translates raw values by means of type conversion
the friendly names are defined as enumeration using the
keyword "enum" (PowerShell 5 or better)
The raw value(s) are translated to friendly text by
simply converting them into the enum type.

Examples
List all instances of Win32_PnPDevicePropertyReal64Array
Get-CimInstance -ClassName Win32_PnPDevicePropertyReal64Array
Learn more about Get-CimInstance and the deprecated Get-WmiObject.

Selecting Properties
To select only some properties, pipe the results to Select-Object -Property a,b,c with a comma-separated list of the properties you require. Wildcards are permitted.
Get-CimInstance always returns all properties but only retrieves the ones that you specify. All other properties are empty but still present. That’s why you need to pipe the results into Select-Object if you want to limit the visible properties, i.e. for reporting.
Selecting Properties
The code below lists all available properties. Remove the ones you do not need:
$properties = 'Data',
'DeviceID',
'Key',
'KeyName',
'Type'
Get-CimInstance -ClassName Win32_PnPDevicePropertyReal64Array | Select-Object -Property $properties
Limiting Network Bandwidth
If you work remotely, it makes sense to limit network bandwidth by filtering the properties on the server side, too:
Get-CimInstance -Class Win32_PnPDevicePropertyReal64Array -Property $property |
Select-Object -Property $property
Selecting Instances
To select some instances, use Get-CimInstance and a WMI Query. The wildcard character in WMI Queries is % (and not “*”).
The parameter -Filter runs a simple query.
Listing all instances where the property Caption starts with “A”
Get-CimInstance -Class Win32_PnPDevicePropertyReal64Array -Filter 'Caption LIKE "a%"'
Using a WQL Query
The parameter -Query uses a query similar to SQL and combines the parameters -Filter and -Property. This returns all instances where the property Caption starts with “A”, and returns the properties specified:
Get-CimInstance -Query "SELECT Data, KeyName, Key, DeviceID FROM Win32_PnPDevicePropertyReal64Array WHERE Caption LIKE 'a%'"
Any property you did not specify is still present but empty. You might need to use Select-Object to remove all unwanted properties:
Get-CimInstance -Query "SELECT Data, KeyName, Key, DeviceID FROM Win32_PnPDevicePropertyReal64Array WHERE Caption LIKE 'a%'" | Select-Object -Property Data, KeyName, Key, DeviceID
Accessing Remote Computers
To access remote systems, you need to have proper permissions. User the parameter -ComputerName to access one or more remote systems.
Authenticating as Current User
# one or more computer names or IP addresses:
$list = 'server1', 'server2'
# authenticate with your current identity:
$result = Get-CimInstance -ClassName Win32_PnPDevicePropertyReal64Array -ComputerName $list
$result
Authenticating as Different User
Use a CIMSession object to authenticate with a new identity:
# one or more computer names or IP addresses:
$list = 'server1', 'server2'
# authenticate with a different identity:
$cred = Get-Credential -Message 'Authenticate to retrieve WMI information:'
$session = New-CimSession -ComputerName $list -Credential $cred
$result = Get-CimInstance Win32_PnPDevicePropertyReal64Array -CimSession $session
# remove the session after use (if you do not plan to re-use it later)
Remove-CimSession -CimSession $session
$result
