Functions

  Marker

NORM :

displays frequency (7 digits max) and level (4 digits max) at marker point.

DELTA :

displays difference frequency and level between 2 markers.

 

  Peak search

NORM :

searches a peak point within 10div. Available NEXT peak (10max).

ZONE :

searches a peak point within a zone designated by center and width. Marker moves to a peak point each sweep.

 

  Calculation

NORM, MAX HOLD, MIN HOLD, AVERAGE, OVER WRITE
* MAX/MIN HOLD : 2 to 1024 times, AVERAGE : 2 to 256

  Measuring

  AUTO tuning

When pressing AUTO TUNE key, the maximum level spectrum within 3.3GHz bandwidth is adjusted to center, and reference level, RBW, VBW and sweep time are adjusted to optimum values.
