Hi,

I have a synthetizer Agilent E8257D (with options : UNY, 540, 1E1, 1EU and IEH) and I would like to drive it with IVI (with LabVIEW).
How can I enable (and disable) the option 1EH (improved harmonics below 2 GHz / setting of low pass filter). I think, this function doesn't exist in IVI.

I have the same question for this option : "optimize SNR".

Thanks,

Benjamin

Hi,

I finaly drive the synthetizer in VISA because the IVI command-set is poor.
I can now set all the options that I need sush as the 2 I asked few days ago except another one : "optimize phase noise below 250 MHz (RF path [normal] OR Low phase noise below 250 MHz)".
I didn't find the command in the "SCPI command reference" pdf file, someone knows the command ?

Regards,

Benjamin

Hi -

In general our instrument drivers cover about 80% of instrument functionality. For functionality that is not used as often for which we don’t include a driver function, customers can use the pass-through functionality in the driver to send SCPI commands to the instrument. Here’s an example of using a pass-through command for a Spectrum analyzer (note: for a signal source this syntax would be similar):
return=agilentSaClass.System.IO.IO.WriteString(“FREQ:CENT 1e9”)

To look up SCPI commands for an instrument, please refer to the programming guide for the specific instrument.

Hi,

I know how to send a SCPI command to the instrument but my question is : What is the SCPI commands for the option "optimize phase noise below 250 MHz (RF path [normal] OR Low phase noise below 250 MHz)" ? I didn't find it in the PDF programming guide.

looks like someone needs to put these commands in the manual...

Thank you very much, it works (but I search "LBP" in the programming guide and didn't find it).

Another question (easier) : How can I ask to the equipement to go back in "local" at the end of the configuration ?
I try "SYST:COMM:GTL", there is no error but it doesn't work.

Regards,

Benjamin
