Getting Started
Dim myMgr As VisaComLib.ResourceManager
Dim myScope As VisaComLib.FormattedIO488
Set myMgr = New VisaComLib.ResourceManager
Set myScope = New VisaComLib.FormattedIO488
' Open the connection to the oscilloscope. Get the VISA Address from the
' Keysight Connection Expert (installed with Keysight IO Libraries Suite
).
Set myScope.IO = myMgr.Open("<VISA Address>")
' Clear the interface buffer and set the interface timeout to 10 seconds
.
myScope.IO.Clear
myScope.IO.Timeout = 10000
When you are using GPIB, CLEAR also resets the oscilloscope's parser. The parser
is the program which reads in the instructions which you send it.
After clearing the interface, initialize the instrument to a preset state:
myScope.WriteString "*RST"
Using :AUToscale to Automate Oscilloscope Setup
The :AUToscale command performs a very useful function for unknown waveforms
by setting up the vertical channel, time base, and trigger level of the instrument.
The syntax for the autoscale command is:
myScope.WriteString ":AUToscale"
Using Other Oscilloscope Setup Commands
A typical oscilloscope setup would set the vertical range and offset voltage, the
horizontal range, delay time, delay reference, trigger mode, trigger level, and
slope. An example of the commands that might be sent to the oscilloscope are:
myScope.WriteString ":CHANnel1:PROBe 10"
myScope.WriteString ":CHANnel1:RANGe 16"
myScope.WriteString ":CHANnel1:OFFSet 1.00"
myScope.WriteString ":TIMebase:MODE MAIN"
myScope.WriteString ":TIMebase:RANGe 1E-3"
myScope.WriteString ":TIMebase:DELay 100E-6"
NOTE
Information for Initializing the Instrument
The actual commands and syntax for initializing the instrument are discussed in
“Common (*) Commands,” starting on page 179.
Refer to the Keysight IO Libraries Suite documentation for information on initializing the
interface.
