Operation steps of short correction function 

1)

 

On <MEAS DISP> page, press the key 

[CLEAR]

, the following soft keys will 

be displayed: 

„

 

SPOT OPEN 

„

 

SWEEP OPEN 

„

 

OPEN OFF ON 

„

 

MORE 1/2 

2)

 

Press the soft key MORE 1/2, the following softkeys will be displayed: 

„

 

SPOT SHORT 

„

 

SWEEP SHORT 

„

 

SHORT OFF ON 

„

 

MORE 2/2 

3)

 

Connect the test fixture to the test ports. Short the test fixture by using short 
plate. 

4)

 

Press 

SPOT SHORT

, U2836 will make short correction on the current 

frequency. 

5)

 

Press the 

SWEEP SHORT

 soft key, U2836 will test the short spurious 

impedances (resistance and reactance) of 37 frequencies. Short full 
frequency correction takes about 20 seconds and in this process, the 
following soft keys will be displayed. 

„

 

CANCEL 

This soft key can be used to cancel the current short correction operation and 
reserve the formal open correction data. 

6)

 

Press 

SHORT OFF ON

 to turn ON/OFF the short correction function. If 

ON,U2836 will make short correction calculation in latter test. If OFF, no short 
correction calculation will be performed in later test.
