Abs Stop and Rel Stop are both set to Couple.
Offset
Key access: [MEAS] > {SEM} > {Offset/Limits}
Selects the offset pairs (upper and lower) that the
softkeys affect, and displays the memory selection
menu from A to E (where you can store up to 5
sets of values for Start Freq, Stop Freq, Sweep Time,
Res BW, Meas BW, Abs Start, Abs Stop, and so forth).
Press Offset until the letter of the desired offset (A,
B, C, D, or E) is underlined. Only one selection at
a time is shown on this key label.
Start Freq
Key access: [MEAS] > {SEM} > {Offset/Limits}
Specifies the inner limit (frequency closest to the
carrier) for both segments of the specified offset
pair. When Start Freq (Off) is selected, the offset pair
is not measured.
Stop Freq
Key access: [MEAS] > {SEM} > {Offset/Limits}
Specifies the outer limit (frequency furthest from
the carrier) for both segments of the specified
offset pair. The minimum frequency difference
between Start Freq and Stop Freq is limited to 100 Hz.
