Procedure
Low Sensitivity Measurements @ 2 GHz
1
Connect the microwave signal source to scope channel 1 as shown in the connection
diagram above.
2 Set up the scope as follows:
a Press Default Setup.
b Set channel 1 vertical sensitivity to 1.0 V/div.
c Set the horizontal scale to 2 ns/div.
Low sensitivity mode: 54855A: 0.5 div p-p 0 to 2 GHz, 1.0 div p-p 2 to 4 GHz, <2.5 div @ 5 GHz
54854A: 0.5 div p-p 0 to 2 GHz, 1.0 div p-p 2 to 4 GHz
54853A: 0.5 div p-p 0 to 2 GHz, 1.0 div p-p 2 to 2.5 GHz
High sensitivity mode: 54855A: 0.2 div p-p 0 to 6 GHz
54855A: 0.2 div p-p 0 to 4 GHz
54855A: 0.2 div p-p 0 to 2.5 GHz
