Meas Setup
Offset/Limits Accesses the following parameters for offset frequency settings and
pass/fail tests:
Offset, Start Freq, Stop Freq, Sweep Time, Res BW, and
Limits. The following Tables show the default settings for BTS and MS
measurements.
Key Access:
Meas Setup
Offset
A B C D E
Allows you to select an offset that will determine the
settings of the parameters in the Offset/Limits key
menus. The default settings for 5 sets of offsets (A
through E) for both MS and BTS measurements are
shown in Table 2-1, and Table 2-2. Press Offset until
the letter of the desired offset (A, B, C, D or E) is
underlined.
Start Freq
On Off
Allows you to specify the limit (start frequency) for the
upper segment of the specified offset pair, and to toggle
this function between
On and Off for each offset.
Stop Freq Allows you to specify the limit (stop frequency) for the
upper segment of the specified offset pair.
