I've noticed that some dboards have RSSI sensors while others don't.
Since I'm using a SBX (rev 3) which doesn't seem to have such a sensor,
I'm wondering if it's also correct to use the magnitude of the samples
as an indicator for the RSS or is this value somehow "distorted"?
Cheers,
Matthias
Hi List,
is there any documentation about the e-series of the usrps (except the
application notes and the datasheet) out there?
I'm especially searching for informations about how to install the
images, how to start and -- at best -- a little example application.
Cheers,
Matthias

Hi,
still have the error with the latest git of uhd:

Hi,
is it possible to generate a PPM signal with GNU Radio + USRP2 with a
bit rate of 1MBit/s?
In particular, I want to transmit Mode-S replies which are modulated
using PPM on 1090Mhz. In order to do so, I have to send 0.5µs wide
pulses with time-shifts of 0 µs or 0.5 µs.
The generation of
Well, I set the ATR registers as follows:
#define atr_reg(x) *(uint16_t *)(0xE400+x)
// set ATR registers
atr_reg(ATR_IDLE_TXSIDE) = (HB_PA_OFF_TXIO | TX_DIS_TXIO);
atr_reg(ATR_INTX_TXSIDE) = (ANTSEL_TX2_RX1_TXIO | HB_PA_OFF_TXIO |
TX_ENB_TXIO);
atr_reg(ATR_INRX_TXSIDE) = (AN
Hi List,
I'm using the latest uhd fpga code and my own f/w on a USRP2 with the
XCVR2450 (REV 692) dboard.
After the tuning is done by the host, sending from f/w is no problem.
Also receiving works fine after setting
sr_rx_ctrl->cmd = (0xE000 | BP_NLINES);
sr_rx_ctrl->t

Hi List,
I'm currently working on a standalone firmware app for USRP2. My goal is
to send a constant signal with the xcvr2450 dboard. I skipped the tuning
via firmware by doing this prior from a host using the simple_usrp c++
interface:
uhd::usrp::simple_usrp::sptr sdev = uhd::usrp::simple_u
Solved it: I was using the wrong Makefile. Using the Makefile.udp, it
work's fine.
Cheers,
Matthias

Hi List,
I compiled the newest fpga code from the uhd-repository (u2_rev3) with
Xilinx' ISE 12.2. I also used the newest firmware which is available
online (20100901) and also tried some other versions but the USRP2 does
not send a response to arp requests or icmp ping messages. So
uhd_usrp_probe
Hi List,
I'm working on a firmware for a completely standalone usrp2 sender.
How is that 32 bits integer dsp_tx_regs->freq interpreted by the
hardware and which value do I need to send e.g. on the 802.11g channel
11 (2.462 GHz)?
Cheers,
Matthias

Hi list,
I want to send data direct from the firmware without host. I looked at
the tx_standalone.c and there came up some questions:
1. Do I have to encapsulate my data into a ethernet packet like it's
done there or can I simply put something into the buffer pool and set
the first_line-argu
