Configuring the VM700T Video Measurement Set

Consider the following lines from a user-generated Timed Events file named
“daily_events”:
Timed Events File: daily_events
Time Type Channel Standard Selected File
Name
9:30
function mid_morn
15:30 report B NTSC mid_pm
Timed Events files use a 24-hour clock to specify event occurrences. When this
file is the current Timed Events file, the following events are set to occur daily:
H
a function called “mid_morn” is executed at 9:30 a.m.
H
a report is generated at 3:30 p.m., using the Video Source file named
“mid_pm”
Two kinds of timed events can occur: a report can be generated (designated as
event type “report” in the Timed Events file), or a function can be executed
(designated as event type “function” in the Timed Events file). For “report”
events, the measurement set looks in the /nvramØ/ConfigFiles/
Video_Source~Files directory for the file named in the Timed Events file.
For function events, the measurement set looks for the function named in the
Timed Events file in directory /nvramØ/FunctionKeys/Timed~Functions. The
function selected as a Timed function must reside in the Timed~Functions
subdirectory (displayed by the Function Keys soft key in the Configure menu).
The parameters for the Auto report (selected measurement limits, measurement
locations, etc.) are specified by the selected file in the Source_Selection~Video
file.
When a report time occurs, the measurement set screen shows the Timed Report
display (unless the measurement set is in remote mode; see note below). The
Timed Report display includes a status line showing the channel and the Selected
Measurements file in use, a soft key labeled Cancel Report, and the measure-
ments being made. Pressing the Cancel Report soft key halts the timed report
execution. Once the report is complete, the measurement set returns to the mode
it was in when the report began. The Copy button flashes until the report is either
printed or canceled with the Cancel Copy soft key in the initial Configure menu.
When a function time occurs, the measurement set executes the function. When
the function has been executed, the measurement set remains in the state
specified by the body of the function; it does not return to the state it was in
when function execution began.
