3GPP FDD code domain power measurements 
on base stations
The ¸FSH-K4 option allows the  code  domain  power  measurements  on  a 
3GPP  base  station.  It  measures  the  total  power  and  the  power  of  the  most 
important code channels, such as the common pilot channel (CPICH), primary 
common control physical channel (P-CCPCH), primary synchronization channel 
(P-SCH)  and  secondary  synchronization  channel  (S-SCH).  In  addition,  the 
frequency offset of the carrier frequency and the error vector magnitude (EVM) 
are measured and displayed. ¸FSH-K4 provides an automatic function for 
fast and optimal setting of the reference level. In the case of base stations with 
two antennas, the user can select which antenna the spectrum analyzer should 
synchronize to (antenna diversity).

Locating EMC weak spots
The  Near-Field  Probe  Set  ¸HZ-15  is  a  diagnostic  tool  for  locating  EMC 
weak spots on printed boards, integrated circuits, cables, shieldings and other 
trouble  spots.  The  Near-Field  Probe  Set  ¸HZ-15  can  handle  emission 
measurements  from  30 MHz  to  3 GHz.  Its  sensitivity  can  be  enhanced  by 
adding  the  Preamplifier  ¸HZ-16,  which  has  a  frequency  range  of  up  to 
3 GHz, a gain of approx. 20 dB and a noise figure of 4.5 dB. In combination with 
the  ¸FSH,  the  preamplifier  and  near-field  probe  set  are  a  cost-effective 
means of analyzing and locating sources of interference during development.
