Hi,

First , sorry for my english, ill try to write my best as french student

I explain first what I want to do and after my questions :

-> 1) I want to give the analyser my own simulate waveforms from exercices
2) and acquire the results on my computer or to watch it on the screen

so :

a) is it possible to give data to the analyser ? maybe with a program as systemvue or matlab
if yes could someone explain me how ? ( i have for the moment make a usb connection and have downloaded the IO suite)
or maybe a program and a special cable connecting the entry plug with a computer ?

b) I would like to know if it is possible to acquire the data that the analyzer give
just want to know if i can watch the same screen on my computer as on the analyser
or if i ave to screenshot all and take it back with my usb key

Thanks in advance for the ones who can help me ^^

No one else has this question

ok i known now that i have to connect my laptop with the input of the analyzer ( RS 232/others to BNC )

now i am searching to retrieve the data analysed , if someone can help ^^

Hello -

Q1: You mentioned you have already generated your own simulated waveforms from exercises. What’s the type for the simulated waveforms? N9320B currently only accepts the RF input.

Q2: You can view the trace data via N9320B PC software on the computer with the same screen, and you can slso capture the trace result screenshot on the local unit directly, or on the external storage drive via USB connection.

Local mode or USB mode setting reference: [File]>{Catalog}>select {Local or USB}>{Return}>{Save}

I hope this was helpful -

Hi again,

I think you have understood what i wish to do

for exemple , i have record a 'white noise' and i want to analyze it to create a filter ( so it s a correct RF signal)

Q1: i have the sound recorded (for exemple in 'wav' or ' flac' or 'mp3' ) and I have to connect to the input plug , but which cable ?
-> i understand i need usb to bnc but i don t find this type of cable . Do you have any references/name ?
or have I to connect my output sound to the analyser input ?

Q2: I have downloaded the latest version of Agilent IO control , connected to the analyser with usb (and lan in a second time), that program recognize the analyser (for each) but i don t find the file/data/usb_or_lan /return/save way you wrote me
Is there an another program i have don t see ?

Q1: There is no such cable type as you mentioned, USB to BNC. You can connect the output to the RF input for Spectrum Analyzer, note the N9320B only supports frequency range beyond 9KHz.

Q2: My apologies, I misunderstood. (It is not your English - which is much better than my California-French!). You meant that you need the process to store the screenshot on the USB drive.

Connect the I/O libraries and right-click the USB port and send command to the instrument.

Select the Save Path :MMEMory:DESTination USB (Local)

Store a Screen Image in a Graphic File: :MMEMory:STORe:SCReen “file_name”

Now you can view the screenshot on the USB drive.

Thanks a lot, now that's working (I just had to make a filter for the low frequencies for safety)

Hopefully , they are people working on micro-control-card who have a special modified cable (hand maded) to send the data from the output parallal port of a pc to the bnc input.

Work in progress! Merci ! :P
