Ultrasound Range for PS 2204A
Ultrasound Range for PS 2204A
Hi,
how well does signal generation and spectrum analysis work for the frequency range of 100khz-900khz? I am studying low cost methods for gas and fluid flow analysis as well as collision detection using ultrasound at these ranges. The PS 2204A seems like a very affordable choice.

Hi, With a 2204A connected in spectrum mode, I have set the range 2MHz and the zoom to 100kHz-900kHz
And increased the Number of Bins to max. of 1048576 giving-
Bin width 1.49 Hz
Bins 4096
Collection time 2.58ms

Re: Ultrasound Range for PS 2204A
There is a bug in the spectrum setting about the number of bins.
When you set the number of bins to the max value the + buttons is grayed out, if you switch then to the axis and back to the bins tab you can only lower the number of bins but the + stays grayed out.

Re: Ultrasound Range for PS 2204A
So I decided to get started with a 2204A but noticed there is a spike 43kHz even when probes are zeroed and nothing is attached to the probes. Is this a sign the scope might have experienced slight damage? The spike is about -81dbu. Everything else seems to work correctly, measuring frequencies fine up to 1Mhz. Have not tested beyond.
