It passes the pps test.
I just thought it is not working properly because the clock is too fast (5x than pps), and reading time is less than 1 sec.
If that is normal, then my GPS pps signal may be working correctly

Creating the usrp device with: ...
Current recv sock buff size: 50000000 bytes
Using Device: Single USRP:
Device: USRP2/N Series device
Mboard: USRP2-REV3 mboard
RX DSP: USRP2-REV3 ddc0
RX Channel: 0
RX Dboard: USRP2-REV3 dboard (rx unit)
RX Subdev: XCVR2450 (0x0061)
TX DSP: USRP2-REV3 duc0
TX Channel: 0
TX Dboard: USRP2-REV3 dboard (tx unit)
TX Subdev: XCVR2450 (0x0060)
Set time to known value (100.0) without regard to pps:
Reading time 1 second later: 101.000101
Set time to known value (0.0) at next pps:
Reading time 1 second later: 0.871597
Success!
