 enables setting the voltage value 

S

 which is the threshold for releasing the position-

ing pulse output in order eliminate false statements due to antenna side lopes.

The duration of the positioning pulse is adjustable by pressing 

 within a 1 ms pat-

tern. With 

 it is possible to set whether with each crossing of the center axis of the 

Antenna, a positioning pulse is to be generated (e. g. during a back-and-forth move-
ment directly above a Transponder). If not, only one pulse per Transponder crossing 
is output. For a re-newed triggering it would then be essential that the voltage 

S

 falls 

again under the 

Threshold for Calculation-Positioning

 (refer to section 

5.3.2.3 on page 37).

With 

 you can choose whether the Posi Pulse and its corresponding bit are turned 

off in the system status after the time persiod set with 

 or after the voltage 

S

 has fallen 

below the threshold set with

 enables setting the the threshold value which has to be succeeded in order to ac-

tivate the use of the measured voltages in X direction for the calculation. 

 does the 

same for the Y direction. The actual threshold value is determined by the maximum of 
a scan cycle minus the input value.

The 

receiver frequency

 „(

ZF

 = 455 kHz and the bandwidth 

B = 5.5 kHz according to the following formula:

Formula: Calculation of the receiver frequency

As this is a SSB-reception, according to the above mentioned formula the upper side-
band should be set to 1553000 Hz and the lower sideband to 1575000 Hz.
