PRESONUS S1 Artist 3.0 [220/307] Tone generator

Each of the channels can be scaled and offset in the Yaxis, and scaling is shown as percent of full scale per division. (Full

scale is 1.f, equivalent to 0 dB.) All channels can be activated/deactivated by clicking on the colored channel letter.

The time (x axis) can also be scaled and offset. This setting is for all channels. The units follow the samples/seconds switch

on the left, and offset is shown with a green vertical line.

The scope is triggered from one of the following sources:

Slope Triggers when the signal level on a selected signal channel (not the math channel) crosses a threshold

level (which is adjusted by the Level control) in the right direction.

Transients This uses the same audio channel, and the Slope and Level controls still apply, but the transient level

is usually much more narrow: somewhere above 0% and typically around 1.5%.

External Signals Notes sent to the scope MIDI input or not sent at all (free).

Engaging Oneshot turns triggering off after the first received trigger. Retrig waits for one new trigger in case you get the

wrong signal or change the signal.

The Scope display is latching, meaning that a signal is shown only on the second trigger. Note that the scope does not

clear its buffer on stop, so there may be unwanted signal shown until another display trigger occurs.

The Hold control adjusts the length of time shown for a trigger signal, and during this period, no new signal triggers the

scope. This is adjusted in percent of the display width and is also shown in the selected time unit and as a green vertical

line. The display is clipped on a new trigger.

Finally, there is a crosshair for measuring the signals. It has a tool-tip readout using the units displayed in relation to the

selected channel. Use this for measuring distances/differences for the selection, where dB levels are rectified signal levels,

so you can compare positive and negative peak levels.

Tone Generator

Tone Generator is capable of generating noise, frequency sweeps, and other signal types commonly used for signal-path

testing and calibration. The Scope would commonly be used in conjunction with Tone Generator to analyze return signals

at the end of the signal path being tested or calibrated.

The following parameters are available in Tone Generator:

Waveform Choose from sine, saw, rectangle, pink noise, and white noise.

Anti-Alias The saw and rectangle waveforms have Anti-Aliasing engaged by default in order to prevent

aliasing artifacts from appearing.

Frequency Set the tone frequency from 1 Hz to 22 kHz.

Modulation

Wobble Engage this to make the tone frequency move from the set frequency to the modulation Target

Frequency, according to the Modulation settings.

Log Sweep Engage to make the frequency sweep logarithmic instead of linear.

Length Set the length in time of the sweep from Frequency to Target Frequency; range is from 10 ms to

59.9 s.
