8665B Frequency Limits

8665B mode keys

• The [Mode 2] key provides a median range of FM deviation and RF output

switching time, as shown in Table 65.

• The [Mode 3] key provides the lowest noise level at the RF output, FM

deviation bandwidth is narrower, and the RF switching time is slower than

in either Modes 1 or 2.

Table 64 8665B frequency limits

Note: Special Function 120 must be enabled for DCFM

Minimum Recommended PTR (Peak Tune

Range)

PTR =FM Deviation x VTR

Takes into account limited tuning resolution available in linear FM (Special Function 120, refer to “How to access special

functions"
