1. Verified with maximum level input signal (~800 mVpp)

2. The precision timebase performs optimally with a sinusoidal input. Non-sinusoidal signals will operate with some degradation in timebase linearity.

3. 86108B-LBW are shipped with a 3.5 mm (female) to 3.5 mm (female) connector saver on the input channels (P/N 5061-5311). The 86108B-HBW is shipped

with 2.4 mm female to 2.4 mm female connector savers on the input channels.

Precision time base (86108 configurations)

The 86108 has an integrated precision timebase within the plug-in module. The 86108A/B can be triggered through clock recovery of

the observed signal, through an external reference clock into the precision timebase section, or with the precision timebase operating

on the clock signal recovered from the observed signal. The following specifications indicate the 86100 system timebase specifications

achieved when using the 86108A/B plug-in module. (The 86100 mainframe and the 86108A/B module can also be triggered with

a signal into the mainframe. In this configuration, the basic mainframe specifications are achieved.) If the 86108A/B is placed in a

mainframe that has an integrated precision timebase (86100D-PTB), the integrated mainframe precision timebase is disabled.
