CHAPTER 6
The SIM Measurement Screen
■ Band Spectrum – RMS, Max, and Hold values are shown for Console, Processor, and
Microphone.
■ Line Spectrum – RMS, Max, Hold, and THD values are shown for Console, Processor,
and Microphone.
■ Delay Finder – Amplitude and Delay time in milliseconds for Processor, Microphone, and
Result (console to mic).
■ Frequency Response – Amplitude, Phase, and Coherence for Processor, Room, and
Result (console to mic).
6.6.1. Trace Offset
The Values tab in Frequency Response also provides a feature called Trace Offset, which can
be used to move the Live trace and any of the recalled traces in memory locations A through
D up or down in the graph views by 1 dB increments.
Use the [+] and [–] buttons to the right of the offset field to change the offset values.
NOTE: Trace Offset allows the user to overlay traces to aid comparisons, and
to determine the relative level differences between them by reading the offset
values when the traces are overlaid.
Figure 6.12. Use Trace Offset in the Values tab to align traces for comparison
NOTE: Trace Offset can also be accessed in the following ways. View >
Trace Offset brings up a trace offset dialog for the Live Branch and the four
memories where values can be entered. The Data menu has commands for +/-1 dB
steps of offset for both Room and Processor. In addition, Control + 9 and + 10 move
the Room trace, and Control + - and + = move the Processor trace.
