Description of command 

These commands define the levels of the downlink (BS) TCH signal relative to the 

Reference Level

 set via 

CONFigure:RXQuality:BER<nr>:CONTrol[:CSWitched][:TCH]:MSLot:RLEVel

 (see p. 

6.157

). The 

levels are valid for BER tests if the MS is set to multislot operation. 

The level range quoted above is restricted by the condition that the absolute level (calculated from the reference 
level and the relative individual levels) must not exceed the level ranges of the RF connectors. 

Example 

With output connector RF2 and a default used timeslot level of –102 dBm, the individual levels can 
be set in the range –35 dB to +92 dB, corresponding to absolute levels of –137 dBm to –10 dBm.
