How do I get a common 10 MHz
reference signal to my source and PNA-X
when it’s too far to use BNC cables?
• Use low-cost GPS-based satellite
receivers to obtain high-accuracy
10 MHz reference signals
• Place a GPS receiver near transmit
source, and one near the PNA-X
• This approach works for arbitrary
distances, from 100’s of meters
to many kilometers
How can I control
external sources?
1. Connect PNA-X to source via LAN or GPIB
2. Use External Device Configuration feature
3. Under Properties section:
– Type name of external source, change Device Type to Source, and choose
appropriate driver
– Under Device Properties, choose between two trigger modes:
Software CW (trigger cables not needed, but slow), or Hardware List
(fast, but requires TTL triggers)
– When distance between PNA-X and source is too far to use
BNC trigger cables (> 40 meters), then Agilent E5818A trigger box
with LAN hub offers good alternative
