Premium PPM and Vectorscope
Still better measuring with special scales and audio vectorscope: Premium PPM and Vectorscope
Expands the basic 4-channel PPM with additional scales, moving coil instruments and 2-channel audio vectorscope
The Premium PPM and Vectorscope license expands the Basic 4-channel PPM (standard software) with additional scales (Zoom, SMPTE, NHK, ARD+9, et al.), additional display modes (segment, classic), and PPM/VU moving coil instruments with different scales and functions. It also provides up to four 2-channel Audio Vectorscopes and a separate phase meter.
With Multichannel Mode license (SW20001) installed, the Multichannel PPM is also extended with the functions of the Premium PPM. Then, the Multi-Correlator with up to 10 phase meters is available.
- Full implementations of the latest loudness standards and recommendations
- Bargraphs for summed Loudness with Momentary, Shortterm, Integrated values, and Loudness Range (LRA)
- Numerical display of all relevant values like M, S, I, LRA, TPmax, Mmax, Smax, Itime
Premium-PPM
Like the Basic or the Multichannel PPM, the Premium PPM provides vertical or horizontal bargraph displays for the individual channels of the active signal source. It expands its range with scales for special applications (like ARD+9 for broadcasters) or standards (like SMPTE or NHK).
Beside the common "Solid" view (see Basic PPM), a segmented view or the simulation of the gas plasma display included in the former RTW Peakmeters can be selected.

Like the Basic PPM or the Multichannel PPM, the Premium PPM also provides vertical or horizontal bargraph displays for the individual channels of the active signal source. But it expands its range with scales for special applications (like ARD9 for broadcasters) or standards (like SMPTE or NHK).
Additionally, the user can select the bargraph view. Beside the common "Solid" view (see Basic PPM), a segmented view or the simulation of the gas plasma display included in the former RTW Peakmeters can be selected.
The example also shows some of the available function keys, being displayed in the Control Bar for the selected PPM. These keys can also be placed as a separate onscreen keyboard.
Moving Coil
Moving Coil instrument as horizontal PPM stereo (above) and VU stereo display (below)
Combined PPM and Loudness display, when SW20002 is additionally activated
Vertical stereo display with loudness scale, when SW20002 is additionally activated
In 2-channel stereo mode, the Moving Coil instrument can be selected insteed of the PPM. It provides several scales and setting opitons. The selectable PPM (British) or VU displays can be shown as single or combined, vertical or horizontal instruments.
With activated Loudness and SPL Display license (SW20002), also a display with Loudness scales or a combined PPM and Loudness display (BBC mode) are available.

Moving Coil (needle instruments)
(1) The example shows the Moving Coil instrument in PPM mode with vertical Stereo arrangement (separate display for left and right channel).
Move the mouse accross the display elements or touch them to get the corresponding descriptions.
(2) The example shows the Moving Coil instrument in VU mode with vertical Stereo arrangement (separate display for left and right channel).
Move the mouse accross the display elements or touch them to get the corresponding descriptions.
(3) The example shows the Moving Coil instrument in PPM + Loudness mode with horizontal Dual arrangement (left and right channel in one display with additional loudness display).
Move the mouse accross the display elements or touch them to get the corresponding descriptions.
The Moving Coil instrument is only available for audio groups with Mono or Stereo signals and can be used instead of the PPM instrument with bargraph display. It features a genuine emulation of various moving coil level meter types.
Using the modes PPM (1) with different selectable British scales or VU (2) with adjustable lead, the L and R channels of a stereo signal can be displayed in one single (L/R or M/S) or two separate moving coil instruments. If two separate instruments are used, they may be displayed in horizontal or vertical arrangements (see examples).
Similar to this, mode Loudness with a scale according to the selected loudness standard can be used when licence SW20002 is activated.
With SW20002, mode PPM + Loudness provides a combination of stereo PPM and summed loudness meter (BBC mode) (3). This kind of instrument includes the PPM with different selectable British scales and its two needles for L (red) and R (green) in horizontal dual arrangement and an additional scale with a cyan-coloured needle to display one of the selectable summing loudness values M, S or I. The center of the fixed relative loudness scale (–9 to +9) represents the target level of the selected loudness standard, the green marked section the tolerance range.
Audio Vectorscope
The 2-channel Audio Vectorscope displays the phase relationship (Lissajous display) between the two channels of a channel pair in real time on a coordinate plane rotated by 45°. The behaviour of the constantly moving Lissajous figure and its spreading may give information on e. g. the width of stereo base or if there are comb filter effects or phase shifts or rotations in the signal. If you see a straight vertical line, you might have a mono signal.
With the Multichannel Mode license (SW20001), up to four instances and 4-channel display are available.
