[Discuss-gnuradio] USRP2 MATLAB

2012-02-10 Thread Kaleem Rana
Hello everyone, I am using USRP2 with XCVR2450 daughter card with Windows XP and MATLAB R2011a in 2.4GHz ISM band. I am trying to implement a simple spectrum analyzer (based on energy detection) with MATLAB's SDRu package (NOT Simulink!!!). I started with a demo provided with the SDRu package

Hi Andrew, thanks for the reply. I need the RF Frontend to change. I'm doing measurements in order to find out how fast the RF Frontend can tune over more than 25 MHz (on a USRP2). I need some exact data here, e.g. plots. So in fact I want it to tune with no workarounds. And I want to see it tune

[Discuss-gnuradio] WBX Transmit Power Issue

2012-02-10 Thread Reginald Cornwallice
Hello All, I'm having an issue with the transmit power on N210 + WBX not being able to reach the spec'd 100 mW on the data sheet. I'm transmitting a PN sequence at a rate of 1.2 Mchips/second. The values I'm sending to the DAC are +/- 24000 which is a little bit below the full range of the DAC, b

I know this is a stupid question, but I've been bitten by this before: Are you SURE you're cabled to the Tx/Rx connector and not Rx2? @(^.^)@ Ed On 2/10/12 4:30 PM, Reginald Cornwallice wrote: Hello All, I'm having an issue with the transmit power on N210 + WBX not being able to reach the spe
