2.4.1.2  Stop Frequency 

The 

Stop Frequency

 will be the frequency at which the Frequencies List stops, that is, the last 

Receive Frequency (

RF

) in the list. If the number of measurement steps in the list reaches 

100 steps before the 

Stop Frequency

 is reached, then the list generation will stop before it 

reaches the 

Stop Frequency

 and a warning will be displayed to the user (See Section 4). 

Changing the 

Stop Frequency 

will regenerate the list of measurement steps, using the 

measurement 

Mode

 selected.  

2.4.1.3  Step Frequency 

The 

Step

 

Frequency

 will be the increment (or decrement) in Receive Frequency (

RF

) between 

each measurement step in the Frequencies List. If the 

Step Frequency

 is larger than the 

difference between the 

Start

 

Frequency

 and the 

Stop

 

Frequency

 then the Frequencies List 

will contain just the 

Start Frequency

 and 

Stop Frequency

. Changing the 

Step Frequency

 

will regenerate the list of measurement steps, using the measurement Mode selected.  

2.4.1.4  Mode 

The measurement 

Mode

 should be selected according to the type of Device Under Test. 

R&S FS-K30 provides five different measurement 

Modes

:

I

Direct

Fixed IF, LO = abs(RF – IF) 

I

Fixed LO, IF = RF + LO 

I
