Using the DMM and ARB 67Chapter 4
The following explains the methods used. For each method, there is a
testplan available it. The testplans are located in the following directory:
C:\Program Files\Agilent\TS-5400 System
Software\testplan\examples
In all testplans, the Arb connects to the Analog Bus ABus1. To view the
output, connect an oscilloscope to the ABus 1 connector at the front of the
system. Be sure to make the necessary connection to the Mass
Interconnect/Express Connect so the interlock is shorted in order to use the
system (see the appropriate documentation). Instead of an oscilloscope, you
can also use an VXI Technology E1563A Digitizer to read the waveforms
and display them using the appropriate actions.
Downloading and
Executing Waveforms
Using the “Arb_Dl_xx”
Actions
Using the “Arb_Dl_xx” actions to download standard or user defined
waveforms gives you the highest throughput capability. Using these actions,
the waveforms are downloaded the first time the testplan is run. The
waveforms remain in memory and can then be selected any time during
testplan execution. The only time new waveforms are downloaded is when
a testplan is modified.
Each downloaded waveform needs a unique name to keep track of the
waveform. This name can then be used to call a particular waveform in any
part of the testplan as many times as needed. Since both waveform data and
other parameters, such as output voltage are also included with a name, the
waveform will be output the same way every time it is selected.
Note When initializing the Arb for output using the “arbInitiate” action, the Arb
outputs the last downloaded waveform, if “Arb_Select_Wave_By_Name”
is not called before “arbInitiate”. Use the waveform names in the
‘waveform_name’ parameters of the of “Arb_Dl_xxx” actions to select
them.
A typical sequence to generate a waveform is as follows:
1. Setup Arb using the “arbConfOutControls” action
2. Send the setup data to the Arb using the “arbSet” action.
3. Download waveform data using the “Arb_Dl_xxx” action; use a
unique waveform name in the ‘waveform_name’ parameter.
4. Initialize the Arb to output the waveform using the “arbInitiate”
action.
5. Select the downloaded waveform using the
“Arb_Select_Wave_By_Name” action using the waveform name in
the “Arb_Dl_xxx” action.
