Hi,

Hi, I ordered 5 cables U.FL to SMA (10 cm) with eBay:

5x Stecker SMA Buchse Auf Ufl / U. Fl / Ipx / Ipex RF Coax Adapter RG178 Kabel

Hi Ansgar,

you transmit on 2400 MHz and receive on 10500 MHz, where is the 11 kHz shift?

PS Do you use a Leo Bodnar GPSDO?

Digital PLL allows main output reference frequency to have almost any value between 450Hz and 800MHz.

The second output frequency depends on the first output due to a common internal clock, if you need individual flexibility, multiple mini GPS units may be a better choice. If both outputs have the same frequency their relative phase shift can be adjusted. This can be used, for example, to generate two signals with 90° phase shift for use in I/Q mixer.

Hi Adrian,

You are right, maxcpus works, but if you ask printenv maxcpus, maxcpus is not defined.

You have to differentiate between internal and external clock. Ansgar speaks of an external one

Hi Ansgar,

you use the command for the internal reference clock.

I recommend reading: https://wiki.analog.com/university/tools/pluto/devs/booting

The command:

# fw_setenv maxcpus doesn't work, it should be # fw_setenv maxcpus 2

Hallo,

ich habe am 25. März bei DigiKey einen Pluto bestellt und am 29. März die Rev. C geliefert bekommen.

Frohes Osterfest,
