Re: Feedback for version 1.0a here

Hi Steve, I mean such a function by which the white trace becomes flat (0dB - reference line) so the yellow trace will be displayed in relative to the white one. This is because noise generators will not give out uniform output from 1kHz to 2GHz, and also we don't need absolute dBm readings when it ...

Re: Feedback for version 1.0a here

Hi Steve, 1) The "Ref-dBm" control sets the reference level at the top of the screen. In addition, it sets the LNA and IF gains, according to a pre-defined look-up table. At higher reference levels, the total gain will be low, the lower the gain, the higher the noise floor will be. At lowe...

Re: Feedback for version 1.0a here

Hi Steve, 1) - I think you should contact Tech Support regarding the spurious output and higher noise floor of the RSPduo. I also get a slightly higher noise floor with the RSPduo. 2) - BC/FM and DAB buttons: At startup, the buttons are (should be) grey or un-selected, and the filters are disabled. ...

Re: Feedback for version 1.0a here

Hi Steve, thank you very much for your releasing the new version. While I was measuring an airband BPF, RSPduo showed bit different operation than the other two models. I am attaching three screen shots showing the results with RSP1A, RSP2 and RSPduo. Yellow Line: Noise generator is directly connect...

Re: RSP Spectrum analyser software available shortly

Hi Steve,

I see no other issues in display layout. Look forward to an improved version.

Regarding the difference between models, you can please take time as there is the trim function already provided.

Re: RSP Spectrum analyser software available shortly

Hi Steve, Thank you for your reply. 1. I tried to change the region or even the language to US/English, but it did not cure the display issue. The Windows using double-byte codes (such as Chinese and Japanese versions) tend to display characters, spaces and lines larger. Would appreciate it if you c...

Re: RSP Spectrum analyser software available shortly

Hi Steve, Thank you very much for your nice software. I have so far observed two issues. 1. The options will not displayed correctly as per the attached screen shot. I live in Japan and do not have any locale issues for installation, but this may be peculiar to Windows JPN versions only. Hope you ca...
