Measure S-Parameters (NA Mode) continued 

The following NA Mode settings can be made 

before

 or 

after

 calibrating without affecting measurement 

accuracy. 

 

Press 

Scale/Amptd

 to change scale.  

 

Autoscale

  

Adjusts the Y-axis to comfortably 

fit the Min and Max amplitude of the active 
trace. 

 

Autoscale All

  

Autoscales all of the traces on 

the screen. Useful for multi-trace 
configurations. 

 

Scale

 Manually enter a 

scale per division

 to 

view specific areas of the trace. 

 

Ref Level

 Manually set the value of the 

reference line.  

 

Ref Position

 Manually set the position of the 

reference line.  Values must be between 0 (TOP 
line) and 10 (BOTTOM line)  

 

Press 

Measure   1

 then 

Format

 to change the 

format for the measurement. 

 

Press 

BW  2

 then 

Averaqe

 then enter a value for 

the number of trace sweeps to average. 

 

Press 

Marker

 then enter a value to move the 

marker to the X-axis position of interest. 

 

Press 

Limit  8

 then
