DSO26 User Manual

Limiter Screen 

 

 

 

To adjust limiter settings: 

 

 

 

Use the ‘ATTACK’ control to adjust the attack time. 

Use the ’RELEASE’ control for the release time. 

Use the ‘THRESH’ control for the limiter threshold. 

 
Each output has an independent high performance limiter. 
All limiters have an attack range of 0.3mS to 90mS, release times are 2, 4, 8, 16 and 32 
times the attack time and thresholds range from +22dB to –10dB in 1dB steps. 
If the automatic limiter time constant option is in use, all limiter screens will say ‘automatic’ 
and the time constants will be set from the high pass filter frequency. A table of dB to 
Vrms, in case the amplifier sensitivity is given in Volts rather than dB, is in appendix 1. 
The output meters are linked to the time constants of the limiters so true output metering is 
achieved. 
 

 
For further details on this topic, see the section entitled “Output Limiters” on 
page 33.
