VM700T Option 40/41/42 Audio Measurements User Manual
This section describes Option 41 operation where it differs from the operation of
Option 40 and the use of either option in the AV Time Measurement feature of
Option 42.
Option 41 of the VM700T was introduced to provide an added audio input
channel to fill the need for a customer. The extra channel input was found to be
useful enough that it was released as a standard option for the VM700 family of
Video Measurement Sets.
The three separate inputs of Option 41 enables the VM700T to measure the
audio signals from three stereo audio sources. With minor differences, Option 41
operates like Audio Option 40. These include the following differences:
configuration of the Source Selection Audio file
rear panel connector type and pin assignments
The following paragraphs describe these differences. Other information about the
operation of the VM700T Audio Option is contained in the preceding sections of
this manual.
Option 41 is configured like Option 40, except for the Source Selection Audio
file.
The Source Selection Audio file lets you specify an Option 41 audio input (1, 2,
or 3) for a video source (A, B, and C), and then select an appropriate audio
source file (if you want to use an audio source file other than the system default).
To specify audio inputs and audio source files for video sources, use the
following procedure:
1. From Measure Mode, press the Configure front panel button, touch the
Configure Files soft key followed by the
key.
2. Rotate the front panel knob to highlight the source (A, B, or C) for which
you are specifying an audio input and an audio source file.
