I tried to use this driver over built in TCPIP, (without GPIB card). Oscilloscope Firmware version is 3.15. I am not able to read any wavefroms from my oscilloscope. Can someone help.

Wrong driver file provided, the downloaded file is agilent_34401a.mdd, not agilent_e3631a.mdd

The test example is very helpful for reference.

Any body know how to download *.mdd file.It gives me HTML file

I try this driver with the WaveRunne 104xi and i had any problems: sometime, when I try to read oscilloscope waveform, I recive this error:
icgroup.invoke at 90 Reference to non-existent field 'wd'
Why?
Can you help me, please?

Is there a simulink equivalent for reading and parsing NMEA strings from a Garmin or other GPS unit?

good

Setting a DC Value doesn't work. It says in the file it can be set to 5Vdc (10Vdc) by setting the Offset Value. I tried different approaches but was not able to set the DC Value that high because the Offset Value is limited to 0.2 (0.4).

Downloaded this and the rsfsh VXIplug&play instrument drivers. Unfortunately, MATLAB Instrument Control Toolbox 2.5 has a bug, and this won't work.

2007b does NOT fix the bug.

Am unable to rate. Will rate once we can use it.

The good job.
I have made the same script, but using differen NMEA word and obtain information about time and velocity too.
The codes modifies strings looks like:
data='';
while isempty(strmatch('$GPRMC',data))
data = fscanf(obj1);
end
ii=findstr(data,',');
UTC=data(ii(1)+1:ii(2)-1);
Time=str2num(UTC(1:2))*3600;
Time=Time+str2num(UTC(3:4))*60;
Time=Time+str2num(UTC(5:end));
...
Latitude=data(ii(3)+1:ii(4)-1);
Lat=str2num(Latitude(1:2));
Lat=Lat+str2num(Latitude(3:end))/60;
NS=data(ii(4)+1:ii(5)-1);
if (NS == 'S')|(NS == 's')
Lat=-Lat;
end
Longitude=data(ii(5)+1:ii(6)-1);
Long=str2num(Longitude(1:3));
Long=Long+str2num(Longitude(4:end))/60;
EW=data(ii(6)+1:ii(7)-1);
if (EW == 'W')|(EW == 'w')
Long=360-Long;
end
...
And so one.
For displaying there is enough to show simply Latitude and Longitude with N or S, E or W, but to calculation better transfer coordinates.
The same is with time.
I know, that my code is not optimal, but it reads only required information.
  

This driver works terrific for Windows machines--it is much appreciated.

[However, it does not appear to work on Linux machines, which is too bad--I have been trying to keep my MatLab scripts platform independent, so that I can toggle between Windows and Linux computers with MatLab as the portability crutch. Must be some hardware discrepancy when it comes to TCP/IP? Not sure.]
