Pulse Period Source
The instrument provides an internal PLL to generate the pulse period.
However, you can use an external clock source applied to the
CLK/REF INPUT connector instead.
I
NTERNAL
PLL
Internal PLL is used for pulse period generation.
CLK-IN
External clock source is used for pulse period generation.
PLL Reference
Set the frequency reference source for the PLL:
I
NTERNAL
The internal 5 MHz reference.
CLK-IN
An external reference signal at the CLK IN (PLL REF) connector. You
can set the expected frequency of the external reference to 5 MHz or
10 MHz:
Deskew Parameter
Set the deskew of output 1 and 2 in to compensate for different cable
delays.
