Time Interval 1:2
Test
Set the UCT to its default state. Select Time Interval 1:2 as the
measurement mode, 50
Ω
impedance for input 1, Common
mode for inputs 1 and 2 and External frequency standard.
Equipment: Signal Generator
Configure the UCT as follows:
*RST
returns unit to default state.

Ω
impedance
IMP1:ROUT COMM
commons Channels1 and 2
selects external frequency
standard
CONF1:TINT
selects time Interval 1-2
If the UCT is fitted with a TCXO or OCXO oscillator option,
connect the UCT internal reference output to the external signal
source 10MHz Input. Configure the external signal source to
accept the 10MHz reference from the UCT.
Connect the Function Generator to the UCT as shown in Figure
6-3.
Figure 6-3, Time Interval 1-2 Test Configuration
