6 List Sequence Measurements
Source
source. When set to “Uplink”, the source will calculate the uplink frequency using an uplink formula
together with the selected channel band and channel number . When set to “Downlink”, the source will
calculate the downlink frequency using a downlink formula together with the selected channel band and
channel number.

Set Reference Frequency
This key allows you to set the frequency reference. Pressing this key turns the frequency reference state to
ON, sets the reference frequency value to the current frequency, maintains this frequency at the RF output,
and sets the displayed frequency to 0.00 Hz. All subsequent frequencies entered under
Source>Frequency>Frequency are interpreted as being relative to this reference frequency.
When you use a frequency reference, the signal generator outputs a frequency that is set relative to the
reference frequency by the value entered under Source>Frequency>Frequency as follows:
Output frequency = reference frequency - entered frequency
Where:
reference frequency equals the original RF frequency entered under Source>Frequency>Frequency and
set as the reference frequency
entered frequency equals a new value entered under Source>Frequency>Frequency
In addition, the displayed frequency value will be the same as the value entered under
Source>Frequency>Frequency.
If Freq Reference is set to ON with a reference value set, entering a value under
Source>Frequency>Frequency and pressing Set Frequency Reference will add that value to the existing
Freq Reference value.
If you wish to change the reference frequency value to the new value entered under
Source>Frequency>Frequency, first you must set Freq Reference to OFF and then press Set Frequency
Reference.
