Hello,
I'm trying to use the external clock input of the USRP2. Since i'm using
GRC, i tried to modify the xml usrp2_source block (the usrp2_source_xxxx.xml
file) to add this feature. This is what I did:
I added a <-PARAM> section:
<-param>
<name>Clock type</name>
<key>clk_type</key>
<type>enum</type>
<option>
<name>Internal</name>
<key>internal</key>
<opt>fcn:usrp2.MC_WE_DONT_LOCK</opt>
</option>
<option>
<name>External</name>
<key>external</key>
<opt>fcn:usrp2.MC_WE_LOCK_TO_SMA</opt>
</option>
<-/param>
And i added this command in the <make> section:
self.$(id).config_mimo($clk_type.fcn)
Can you tell me if there is a chance for this to work ? And if i am using
the good command to use the external clock (i read that it was also possible
to modify the firware to use the external clock) ?
Thanks in advance.
Damien S.
