Using the Agilent 81133A/81134A Pulse Generator Combining Parameters for Signal Generation
74 Agilent 81133A/81134A Pulse Generator User’s Guide, September 2008
–Ext. Direct
Allows you to vary the frequency of the external clock signal
in the range of one octave.
In external direct mode, the internal PLL is bypassed. This
ensures that the instrument frequency exactly follows the
external clock.
For both, Int. Direct and Ext. Direct, range switching occurs at
the following frequencies:
– 1680 MHz
– 840 MHz
– 420 MHz
– 210 MHz
– 105 MHz
– 52.5 MHz
– 26.25 MHz
NOTE The range- switching frequencies are based on 1680 MHz divided
by the frequency divider.
