Set the UCT to its default state. Select Totalize 1 by 2 as the
measurement mode, 50
frequency standard.
Equipment: Signal Generator
Configure UCT as follows:
*RST
INP1:IMP 50
SOUR:ROSC:SOUR EXT
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 UCT to the signal generator as shown in Figure 6-
6. Set the signal generator to 10MHz, 0dBm. Check that the
UCT measurement result is 5000 +/- 1.
