Can you use a SA44 and TG44 together with an external 10MHz GPS locked reference signal with duel outputs for example from a http://www.leobodnar.com/shop/index.php?main_page=product_info&cPath=107&products_id=234
or does the SA44 have to get its reference signal directly from the TG44 when functioning as a scalar network analyser.

The TG44A hardware only has a time base output, so the only way to lock the SA44B and TG44A together is with TG 10 MHz –> SA 10 MHz
The TG124A has the ability to input or output its 10 MHz reference, so you could use a GPS 10 MHz to discipline both a TG124A and an SA.

Thanks for the information, I do not think I will be upgrading to a TG124A just to be able to get a 10MHz GPS disciplined input it’s not that critical. However when not functioning as a scalar network analyser I will probably lock my SA44B.
