Switchbox
In automatic test systems, it is difficult to
swap BNC cables when you need to mea-
sure on several measuring points. With
the '9X' you can select from two different
basic inputs (A and B), on which the
counter can measure directly without the
need for external switching devices.

Prescaling
For all measuring functions except time
interval, rise/fall time, phase and time
stamping, the maximum input A or B fre-
quency is 300 MHz.
For the measuring functions explicitly
mentioned above, the counter has a max
repetition rate of 160 MHz.
For the measuring functions Frequency
and Period Average, the signal to Input A
or Input B is prescaled by a factor of 2.
For Frequency in Burst, PRF and Num
-
ber of Cycles in Burst, the signal is
prescaled by a factor of 2 if the command
:SENSe:FREQuency:BURSt:PREScaler is
set to ON. This is also the default condi
-
tion.
