This key is used to toggle between Frequency and Channel for your measurements.
That is, you can decide whether to specify (and measure) the frequency in Hertz, to
specify the Channel Number.
Setting the CDMA Transmitter Reference Level
You can set the CDMA transmitter reference level to display either relative power
(dB) or absolute power (dBm). The test set defaults to relative. The top graticule
(horizontal line) represents the total power in the CDMA channel. The scale per

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

, External 10 MHz, and External

. These last three options only
provide a frequency reference. They do not
provide a time reference...
