Hello All,
We recently had to upgrade the receivers on our products to the E320 due to the obsolescence of the E310. While running the same program on the E320 I observed the following issues: 1. AD9361 temperature - on the E310, B210 this temperature used to be around 40 to 45 C, with all channels operating - namely 2 Tx and 2 Rx. MCR of 16 MHz. On the E320, the temperature has jumped to 74C when only the Rx channels are operating, while it goes up to 85C-90C when the Tx channels (i.e. all 4 channels - 2 Tx, 2Rx) are also operating. Is this normal ? 2. E320 specific issue - when streaming data to the host PC, stopping the stream during times of inactivity [self.uhd_usrp_source_0.stop()] actually causes the temperature of the AD9361 to creep up over time. 3. E320 specific issue - when streaming data, reading of the new set of mother board sensors available on the E320 (e.g. FPGA temperature, fan, ref_locked etc) causes the stream to stop, to process the sensor query - is this normal. This does not happen when processing the AD9361 sensor data. UHD version 4.8.0.0 GNU Radio version 3.10.12.0 Python 3.12.9 I would love it if it is something I am doing wrong. All data processing is done on the host, as I understand that the E320 does not support RFNOC updates with a free licence of Vivaldi (unlike the E310). So, the E320 is only being used as a layer between the AD9361 and the SFP module. Thanks, Indrajit.
