RTW Premium PPM and Vectorscope

Still better measuring with special scales, moving coil instruments, and Audio Vectorscope

  • Basic PPM gets further scales like Toom, SMPTE, NHK, ARD+9
  • Comprehensive configurable PPM and VU moving coil instruments
  • 2-channel Audio Vectorscope, and Multi-Correlator with activated Multichannel license

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.


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.

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.


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.


The Multicorrelator instrument displays for the surround channel configurations in Normal mode the phase relationships between all channel pairs available in the surround format used (except LFE) graphically placed in the speaker setup of the respective surround mode. A low pass filter can be activated.
In LFE mode, the instrument displays the phase relationships between every single channel available in the surround format used and the LFE channel.


Practical Use

  • Expand your measuring and application range
  • Meet special requirements
  • Adjust your measuring instruments to country-specific practices
  • Keep your eyes on the quality of stereo signals
  • Monitor the phase relationships of surround signals



  • TouchMonitor TM7, TMR7, or TM9
  • Optional on TM7 or TM9 software license SW20001: Multichannel Mode for the use of the Multi-Correlator
