Setting the Frequency/Time Reference

Setting the Frequency/Time Reference
This key is used to specify the source of your frequency reference, or your frequency and time reference. The analyzer needs an accurate reference signal in order to make accurate measurements, and this is where you specify the source of this reference signal.

Select the frequency and time reference from the list using the up and down arrow buttons.
If the sky (and hence the satellites) is visible from the position of your analyzer, you can select GPS to get frequency and timing references from the GPS signal. The GPS antenna will need to be attached to the analyzer.
If you connect to the access network's Even Second Clock, you will still get all the metrics, but you will not have an independent check that the access network has locked onto the GPS signal.
Other options available are Internal Reference, External 10 MHz, and External 19.6608 MHz. These last three options only provide a frequency reference. They do not provide a time reference...
