Section 3 - Configuring the VM700A
VM700A Option 01 (NTSC) & Option 11 (PAL) User Manual
3-13
Files in the Video_Source~Files directory tell the VM700A where to find
important parameter information. These files contain the following entries:
Auto Limits File: the name of the file in the Auto_Limits directory that
specifies the limits used for Auto mode measurements.
Measure Limits File: the name of the file in the Measure_Limits directory that
specifies the limits used for Measure mode measurements.
Measurements Location File: the name of the file in the Measurements_Loca-
tion directory that specifies the default frame lines and intra-line positions from
which to make measurements, as well as other measurement-related information.
Selected Measurements File: the name of the file in the Selected Measurements
directory that defines which measurements are to be monitored (i.e., potentially
generate Caution and Alarm messages) when the VM700A is in Auto mode.
Auto Sync Source: specifies the synchronization source for Auto mode.
Possible values are: Channel A, Channel B, Channel C, External, or Locked to
Source. The first four use the specified sources for synchronization; Locked to
Source uses whichever source is selected when the VM700A goes into Auto
mode.
Source Name: specifies text to be printed across the top of printouts generated
by Auto mode or the Copy button. This text may be set to any appropriate string
(up to 33 characters) that helps identify the source.
Printout Title: specifies text to be printed (above the Source Name text) across
the top of printouts generated by pressing Copy. This text may be set to any
appropriate string (up to 49 characters) that helps identify the source.
Taken together, the file names and parameter values contained in files in the
Video_Source Files directory define a complete measurement and reporting
environment. This environment is usually associated with a particular configura-
tion of equipment being monitored. Thus, for example, you might create a file in
the Video_Source Files directory called “tx1,” which would define a measure-
ment environment associated with the signal from your primary transmitter. To
avoid confusion, you should give all the files associated with this environment
the same name. (They reside in different directories, so there is no risk of name
collision.)
This arrangement, whereby the file in the Video_Source Files directory defines
the measurement environment while the Video Source file assigns the environ-
ment to a channel, gives the VM700A maximum flexibility in meeting a variety
of signal monitoring needs. Pre-defining a number of different environments
(one for each configuration of equipment to be monitored) allows you to set up
the VM700A for different measurement assignments by simply changing entries
in the Video Source file.
