Power Range Example

The following VB Script example exercises the COM commands used to set up the Power Range feature to access data sheet specified and typical max and min power levels (in dBm). Max power refers to the maximum leveled source power.

This VBScript (*.vbs) program can be run as a macro in the VNA. To do this, copy the following code into a text editor file such as Notepad and save it on the VNA hard drive as RxLevel.vbs. Learn how to setup and run the macro.

Example #1

Set Application = CreateObject("AgilentPNA835x.Application", "A-N5242A-90065")

Set PowerRange = application.Capabilities.PowerRange

powerRange.Reset

powerRange.PortNumber = 1

powerRange.PathElement("Src2Out1LowBand").Value = "HiPwr"

powerRange.RangeStartFrequency = 1e9

powerRange.RangeStopFrequency = 10e9

maxPower = powerRange.RangeGetMaxPower

minPower = powerRange.RangeGetMinPower

 

MsgBox("Max power: " & maxPower & " dBm" & Chr(10) &_

"Min power: " & minPower & " dBm" )

End Function

 

Example #2

Set Application = CreateObject("AgilentPNA835x.Application", "A-N5242A-90065")

Set PowerRange = application.Capabilities.PowerRange

powerRange.Reset

powerRange.PortNumber = 3

powerRange.PathElement("Src2Out1LowBand").Value = "HiPwr"

powerRange.DiscreteFrequencies = Array(1e9,2e9,3e9,4e9)

maxPower = powerRange.DiscreteGetMaxPowerArray

minPower = powerRange.DiscreteGetMinPowerArray

 

MsgBox( "Frequency: " & ArrayToString(powerRange.DiscreteFrequencies) & " Hz" & _ Chr(10) & "Max power: " & ArrayToString(maxPower) & " dBm" & Chr(10) &_ "Min power: " & ArrayToString(minPower) & " dBm" )

 

Function ArrayToString(Arr)

For i = 1 to ubound(Arr)

ArrayToString = ArrayToString & "," & CStr(Arr(i))

Next

End If
