Description

I'm observing a strange behavior when comparing the RF envelope of osmo-trx-lms on a LimeSDR and a LimeSDR-mini.

The LimeSDR-mini envelope is within spec. Specifically, the transmit power level is at full strength before the start of the next burst.

On the LimeSDR however, the next burst/timeslot starts too late, (or the slew rate is too low?):

This is using the exact same versions of LimeSuite (f1e5444496923890ad7d030abef9c224c37c46cf) and osmo-trx (70621b74844a6ea08d6da5f5b1e1835b9af91771). All I'm doing is swapping the hardware and re-starting osmo-trx-lms and osmo-bts.

It's very odd, and I currently have no clue of what might be going on here.

  • Assignee set to roh

roh: please re-perform the LimeSDR (non-mini) tests using a LimeSDR that is clocked from the 10MHz reference of the E4406.

Please also try to modify the ts_offset found in the following line of the source code in osmo-trx/Transceiver52M/device/lms/LMSDevice.cpp:

ts_offset = static_cast<TIMESTAMP>(8.9e-5 * GSMRATE * tx_sps); /* time * sample_rate */

so far i have not been able to get it running well enough so the 4406 will do a gmsk phase and frequency plot. pwr vs time screenshot below. most the time i cannot even get it to trigger properly.

the clock output on the limesdr seems to be disabled (no signal according to the scope)

even in the case of osmo-trx-lms continuing to run the rf signal isnt visible on the 4406 anymore after 3-5 minutes.
the output of osmo-trx-lms keeps printing this kind of information one line per second tho.

to get it working it is not enough to restart osmo-trx-lms. one has also to physically disconnect the limesdr-usb and reconnect it.

the installed limesuite is 18.06 from the debian nighly feeds (everything updated today)
the limesdr usb got updated by using 'LimeUtil --update' (also today)

version dumping in osmo-trx-lms seems still broken:

i will repeat these tests with limesdr-mini now.
