Re: [Flexradio] "Scope" Option on PowerSDR - Is it my video card?
"Setup" - "Display" - "Scope Mode" - "Time (us)" [sic] The Time parameter is the time in milliseconds per horizontal sweep. It works fine for me, though there is no trigger that I am aware of. I just verified it will work with extremely slow "sweep" rates. Looks like 1000 sec is the slowest.

Re: [Flexradio] "Scope" Option on PowerSDR - Is it my video card?
There is an error in the time base calibration. I set the radio to receive a signal generator with a 1kHz AM. Setting the Time (us) to 10 it shows almost 7 full cycles in the scope, so it is closer to ms that us. I had to stop the radio to steady and count it, since I already noted there are not trigger facilities. I think it doesn't worth to report this calibration issue to the bug tracker since it is not needed until more elaborate scope controls are available. 73 de Ignacio, EB4APL - EB4APL wrote: Bill, Here it works more or less as it should. The speed function surely works, but I didn't checked if is really calibrated and I see some discontinuities, for example when looking a sine wave. It lacks trigger functions and a pop-up control panel (maybe in a future version), but I found it quite useful. 73 de Ignacio, EB4APL -- Bill Roberts wrote: When I use the Scope option to examine transmitted and received wave forms with PowerSDR, it doesn't look like/refresh like a real scope.

The "scope" on the Flex has little comparison to a real scope. The panadapter is a gold mine, the scope has what use do not know. --- On Sun, 2/28/10, Bill Roberts wrote: > > When I use the Scope option to > examine transmitted and received wave forms > with PowerSDR, it doesn't look like/refresh like a real > scope.

Re: [Flexradio] "Scope" Option on PowerSDR - Is it my video card?
"I'm wondering if this would improve if I got a better video card? " Not substantially. It is defined by the software. Did you up the "Main Display FPS" values in the Setup->Display tab? See what difference that makes (if any). -Tim -Original Message- From: flexradio-boun...@flex-radio.biz [mailto:flexradio-boun...@flex-radio.biz] On Behalf Of Bill Roberts Sent: Sunday, February 28, 2010 1:28 PM To: FlexRadio@flex-radio.biz Subject: [Flexradio] "Scope" Option on PowerSDR - Is it my video card?
