Numbers 0-9 are available to be used. 
  
2.  Decimal point 
A decimal point “.” will be inserted at the cursor position when this key is pressed.  
 
3.  Sign key 
Sign key “+/-” is to toggle the sign of a parameter. When pressed the first time, a 
“-” will be inserted and changed into “+” following the second press. 
 
4.  Unit keys 
Unit keys include GHz/dBm/s, MHz/dB/ms, kHz/dBmV/µs and Hz/mV/ns. After 
entering the desired numbers, choose an appropriate unit to complete the
