hp 3562a + visual basic

[Bill]

Hello,

I develop a software application that communcate with the hp 3562a in
visual basic. (gpib/national instruments)

I can send commands to the analyser, but I don't know how to get
information out of the analyser. (results)

Here you see some code of my:

Public Const BDINDEX = 0 ' Board Index
Public Const PRIMARY_ADDR_OF_DMM = 7 ' Primary address of
strDevice
Public Const NO_SECONDARY_ADDR = 0 ' Secondary address of
strDevice
Public Const TIMEOUT = T10s ' Timeout value = 10 seconds
Public Const EOTMODE = 1 ' Enable the END message
Public Const EOSMODE = 0 ' Disable the EOS mode

strCommando = "RST"
ilwrt strDev, strCommando, Len(strCommando)
If (ibsta And EERR) Then
Call GPIBCleanup("Error: command RST")
End If

' Swept sine
strCommando = "SSIN"
ilwrt strDev, strCommando, Len(strCommando)
If (ibsta And EERR) Then
Call GPIBCleanup("Error: command SSIN")
End If

' Linear sweep
strCommando = "LNSW"
ilwrt strDev, strCommando, Len(strCommando)
If (ibsta And EERR) Then
Call GPIBCleanup("Error: command LNSW")
End If

' Active trace
strCommando = "A"
ilwrt strDev, strCommando, Len(strCommando)
If (ibsta And EERR) Then
Call GPIBCleanup("Error: command A")
End If

' Freq band
strCommando = "FRS" & txtStartFreq & "," & txtStopFreq & "Hz"
ilwrt strDev, strCommando, Len(strCommando)
If (ibsta And EERR) Then
Call GPIBCleanup("Error: command FRS")
End If

' Freq resp
strCommando = "FRQR"
ilwrt strDev, strCommando, Len(strCommando)
If (ibsta And EERR) Then
Call GPIBCleanup("Error: command FRQR")
End If

' Mag lin
strCommando = "MAG"
ilwrt strDev, strCommando, Len(strCommando)
If (ibsta And EERR) Then
Call GPIBCleanup("Error: command MAG")
End If

' Local
strCommando = "LCL"
ilwrt strDev, strCommando, Len(strCommando)
If (ibsta And EERR) Then
Call GPIBCleanup("Error: command LCL")
End If


'
' ?????????????
'
strCommando = "DDAN"
ilwrt strDev, strCommando, Len(strCommando)
If (ibsta And EERR) Then
Call GPIBCleanup("Error: command DDAN")
End If

How can I get the respons?
Does somebody have some examples?

Thanks for your help and advice,

Hello-

There are plenty of examples in C:\Program Files\National Instruments\NI-488.2\Languages\Visual Basic when the GPIB driver is installed.
