Hi Josh, Yes, I forgot about that, it's just that the default sample rate in GRC was set to 32k, and I overlooked that. I've pulled in and compiled the latest SRCREVs from both the gnuradio and ettus uhd repositories, on Fedora 12. I've set it to 100 Msps, and connected it to a Null Sink, and I get an error message saying that the target hardware doesn't support 100Msps. I have a USRP2 which has a sample rate of 100Msps. Why is it switching to 25Msps? Here is the output: Executing: "/home/elvis/Desktop/grc-examples/top_block.py" Current recv sock buff size: 50000000 bytes Current send sock buff size: 50000000 bytes Using: WBX TX (0x0053) Using: WBX RX (0x0052) RX samples per packet: 362 TX samples per packet: 363 Recv pirate num frames: 33967 The hardware does not support the requested sample rate: Target sample rate: 100.000000 MSps Actual sample rate: 25.000000 MSps gr_block_executor: source <gr_block uhd simple source (2)> produced no output. We're marking it DONE. >>> Done Best regards, Elvis Dowson |
