Pure sinusoidal signals are required for many standard audio
measurements. The Digirator provides a wide and adjustable
output level range and selectable output frequencies.

Output frequency
Output level
Sweep
Characteristics and use
Stepped sweep signals with a resolution of up to 1/12 octave
can be generated over a freely-selectable frequency range. An
audio analyzer like the Minilyzer or Digilyzer from NTi Audio can
automatically trigger to this signal sequence to measure the
frequency response.
Starting the Sweep signal
1. Select the “START” symbol
with the rotary wheel.
You can interrupt a running sweep via the “STOP“
symbol.
