we want to display "Frequency point" on TV display.
so, we prepare a OSD(on display screen) device with RS232 interface.
and I don't know how to output word of "frequency point" through RS 232 interface from signal generator of keysight N5171.
could you give me some suggestion?
Hello ke68898,
I am in agreement with Tardz in that I'm not entirely sure what you need to do. Indeed, there is no RS-232 capability for the N5171B. Could you clarify? What do you mean by frequency point? Did you make your own display? Is the only way to communicate with the display via RS-232?
If what you're trying to do is display the frequency on a screen, there are two easy ways you can achieve this:
1.) You can use the web interface to display the front panel in a web browser, instructions are here:
X-Series Signal Generators Programming Guide (page 12 [PDF page 20])
2.) You can use the Keysight I/O libraries and send a SCPI command to the instrument and it will return the frequency. Instructions to download the libraries are here: IO Libraries Suite | Keysight (formerly Agilent’s Electronic Measurement)
The command you would want to use is :FREQuency?
Instructions are here: X-Series Signal Generators Programming Guide
Hope that helps!
