SIM 3 Release Notes

Version Release 1.7.0 - July 24, 2006 - Code Date: June 28, 2006

SIM System II Files

Sim 3 can now import Sim System II files and data.

Galileo 616 (Must have Galileo Firmware 1.7.0)

Branch Setup > Switchers: Addresses 10-14 are now reserved for Galileo 616. To measure a Galileo using SIM3 simple connect the buss cable between the 2 devices using the Line Switcher port on the back of SIM3. There are 3 branch combinations available when measuring the Galileo:

Combination One:
Console = Galileo Output Post Matrix (ex. Ad 10, Ch 1 Sw 10, Cons 1). This uses the output of the Galileo Summing Matrix as the signal that feeds the Console buss.

Processor = Galileo Output Post Processing (ex. Ad 10, Ch 1 Sw 10 Proc 1). This uses the output of the Galileo Output Processing as the signal that feeds the Processor buss.

Note: Selecting Cons 1 on the Console channel will automatically select Proc 1 on the Processor channel. The transfer function shown will represent the output processing applied using Galileo.
Combination Two:
Console = Front Panel Signal Generator (ex. Ad FP Ch 0 Generator). The SIM signal generator is used as the signal that feeds the Console buss.

Processor = Galileo Output Post Processing (ex. Ad 10, Ch 1 Sw 10 Proc 1). This uses the output of the Galileo Output Processing as the signal that feeds the Processor buss.

Note: The transfer function shown will include any input and output processing applied using Galileo and/or the mixing console.
Combination Three:
Console = Front Panel Line Input 1 (ex. Ad FP 1 Line In 1) This uses the signal received at Line Input 1 which can be in parallel to the console output feeding Galileo.

Processor = Galileo Output Post Processing (ex. Ad 10, Ch 1 Sw 10 Proc 1). This uses the output of the Galileo Output Processing as the signal that feeds the Processor buss.

Note: The transfer function shown will include any input and output processing applied using Galileo and/or the mixing console.

Navigation

Delay Finder: Autoset Delay now much faster
Frequency Response: Delay Times now listed at the top of each measurement window
Shift+F7 and shift+F8 control master gain, all gains move up/down together.
Right-clicking on generator buttons now brings up appropriate generator dialog.
On-screen buttons for zoom select, branch and gains now have mouse-over help windows (tool tips, balloon help).
Generator: selecting sine wave now allows user to enter a value for Cal (the value in Vrms when the generator knob is fully clockwise).

Help

Help > Shortcuts: Displays a list of all available keyboard shortcuts.
Help > About window now shows % of compact flash used. A warning will be displayed when compact flash filled to 95% or more.
Help > About window now shows screen resolution.

Display

Settings > Choose Colors: Customizeable trace colors, available under single view only.
Vertical scale settings are now stored with the project.
Calibrate Mic dialog now displays mic sensitivity in mV/Pascal.

DataGroup functions

Data > Store: Grid view now available for storing and recalling traces.
Data Store/Recall: Input meters average and peak values are now stored with the measurement, and displayed on the data store/recall panel.

Frequency Response

Phase 0 or 180 degrees center may now be selected by clicking on the vertical ‘deg’ label to the left of the phase screen.
Processor or inverse processor (1/processor) may now be selected by clicking on the ‘Processor Amplitude’ or ‘Processor Phase’ labels above the trace screens.
Percent or dBSN may now be selected by clicking on the vertical ‘percent’ label to the right of the coherence display.

Bug Fixes

Stability improved for projects containing more than 32 Branches.

Version Release 1.6.42

Display

Set display to show dark traces on white background for greater visibility in sunlight and better printouts
Export screenshots to .bmp files
Export or print DataViewer to .bmp files
Safe status shown on Speaker and Switcher tabs

Navigation

Onscreen horizontal zoom buttons in Band Spectrum, Line Spectrum and Frequency Response displays
Keyboard control of graph cursor movement

Microphone functions

Microphone calibration for accurate SPL readings (requires third-party mic calibrator tool)

DataGroup functions

Delete multiple DataGroups
Edit notes for previously-created DataGroups
DataGroups saved with new international date format

Bug Fixes

DSP Driver Bug: On rare occasions, some SIM 3 machines would freeze at startup during the splash screen. Install and Recovery v1.6.42 installs a new DSP driver to fix this problem.
DSP Firmware Bug: A small number of early SIM 3 machines were shipped with DSP firmware that was incompatible with v1.6.0. Install and Recovery v1.6.42 now checks and updates the DSP firmware if necessary.
The Switcher tab configuration anomalies have been solved.
A capital letter M (Shift + M) can now be entered without difficulties.
Meter gains will now track Branch 0 FP Mic 1.
