Press TRIG to bring the ruler on if you need to measure exact values of individual discretes. Move the ruler with one finger. An exact signal level value corresponding to the ruler position is displayed in the top-left corner.
Press TRAC to switch to spectrum track mode. While in spectrum track mode the vertical ruler turns into scale with marks for seconds and tens of seconds.
Press STAT to enable real-time statistics: max — highest sample value min — lowest sample value avg — average sample value mdz — mean deviation around zero sd — standard deviation sum — sum of sample values int — area between sound wave and zero
Press PLAY to enable repeated playback of the buffer cut by time window bounds.
The trigger point is on the rising edge of a signal above or equal to zero and on the falling edge of a signal below zero.
OSCILLOSCOPE
One shot triggering: Make initial adjustments, press TRIG and position the ruler as when triggering with holdoff. Release TRIG and press TRIG again to flush the buffer. Make sure that there is no signal captured in the view. Press HOLD. After this point the oscilloscope is waiting for just one first trigger event. Release HOLD and press HOLD again to reload for another single shot. Release TRIG to study a waveform.
All controls are visible on the screen. Oscilloscope and spectrum views are independent of each other.
High quality digital storage oscilloscope with spectrum view.
SPECTRUM
Sample rate: 48 kHz Buffer size: 1 second Signal source: microphone
Press HLDA to freeze both spectrum and oscilloscope. Pressed HLDA button manifests that views have been set on hold together and display mutually relative data.
MANUAL
Triggering with holdoff: Zoom in and adjust scale division values as needed. Press TRIG and position the ruler according to a signal level and a time distance to trigger on a correct part of a signal. When triggered press HOLD and then release TRIG to study an interesting part of a waveform with navigation, zoom and playback. Holdoff period is defined by a time distance between the ruler and the right edge of the view.
Press HOLD to freeze.
Press AUTO to make the ruler follow dominant frequency. Note that it is possible to move the ruler while in HOLD mode and to temporarily move the ruler while in AUTO mode.
Turn on the view. Scale division values are displayed in the bottom-left corner as second x discrete. Signal level scale is on the right side. Touch and drag with one finger to navigate a waveform, touch with two fingers to zoom.
Press HOLD to freeze the buffer. While in HOLD mode it is possible to navigate to the past up to one second. Time shift in microseconds, if present, appears in the top-left corner.
Turn on the view. Move the vertical ruler to display frequency with maximum precision at any position along the spectrum view.
