Option VGA Setup 2 - VGA Connector to 5X Cable
Use this setup for testing PC and play-out device video when it is not convenient to use the RGBHV M easurement
Interface Unit. To ensure accurate measurements, connect the signals to the VM Series system using the T-connectors
and precision terminations on CH1-CH4. You must use 75 Ω terminations on CH1–CH3 (used for GBR) and 2.21 kΩ and
301 Ω terminations on CH4 (used for H Sync and V Sync m easurements). This method requires you to change the signal
and termination connections on CH4 for certain horizontal and vertical measurements. The VM Series system displays a
dialog box prompting you to m ake these changes when necessary (the RGBHV Measurement Interface Unit performs these
connection and termination changes internally).
To connect the DUT to the VM Series system using a VGA to 5X cable:
1. Install the included 75 Ω terminations
between the end of the BNC cables and
the instrument input channels 1 through
3, using the included BNC T-connectors.
To achieve accurate measurements, it
is important to attach the T-connectors
directly to the input channel BNCs.

Signal Path Compensation
To optimize measurement accuracy, see the oscilloscope online help to perform the instrument signal path compensation
procedure. Use the procedure if the temperature has changed more than 5 °C since the last signal path compensation.
Perform the signal path compensation once a week. Failure to do so may result in the instrument not meeting w arranted
performance levels at those volts/div settings .

About the Matrix Test Signal
The Matrix test signal is supplied on the accessory signal source disks included with this product. There is a Matrix signal for
Options SD and HD and a Matrix signal for Option VGA. The Matrix signal incorporates all analog video signal requirements
into different line numbers within one test pattern field. Using a single test pattern eliminates the need to change test
signals when doing different measurements. All you need to do is specify line numbers on which measurements are taken.
Use the setup file (.vmset) that matches the format of the Matrix test signal you are using; this provides appropriate line
numbers as default settings for each measurement type. See the VM Series Video Measurement System User Manual for
a full description of the files on the signal source disks.

Simple Color Bars Measurement – Options SD/HD
Amplitude measurements are typically performed using the color bars test signal, which switches the R′G′B′ components on
and off to produce all eight possible color combinations (White, Yellow, Cyan, Green, Magenta, Red, Blue, and Black). There
are a variety of different forms of the color bar test signal, typically either using a maximum dynamic range of 700 mV = 100%
or at 75% with an R′G′B′ amplitude of 525 mV. In the following tables, the amplitude ranges for the component Y′P′bP′rare
given for the various standards of 100% and 75% color bars.

Depending on the type of equipment being tested, a variance in the actual values is allowed. For example, the progressive
outputs of DVD players can introduce setup to their outputs that can vary the overall measured results. Variations in the
level of the components can introduce different hue and saturation in the displayed picture. The color bar test signal lets
you check for gain inequalities between the channels and to ensure that the signal is not distorted, which could produce
severe clipping of the signal.

Taking Measurements Across Multiple Lines
When the VM Series system takes a measurement, where the measurement is taken (you c ould also say when the
measurement is taken) is specified by the line number. (If you want to measure the Luma Level, you need to make sure the
measurement is taken within the active video portion of t he signal.) Sometimes you w ill need to take a measurement across
more than one line. (For example, you might need to verify that the Levels are consistent from the top to the bottom of the
display.) To do this, use the Multi Lines setting under Line Select on the Operation tab. Each measurement requires an
appropriate signal pattern to be present on a specified line of the input video signal. This line number setup parameter is
configured via the "Line Number" input box in the measurement’s results panel. The signal pattern is generally available on
multiples lines of the input signal. The measurement can be performed by specifying any of those individual lines.
NOTE. Some measurements are not available in Multiple Lines mode. The Setup Only, Run Only and Continuously settings
(Operation panel) are not selectable in M ultiple Lines mode.
When the instrument is in Multiple lines mode, measurements are performed sequentially on each of the line numbers in the
range specified for the selected measurement(s). The results for the individual lines are averaged and then displayed in the
measurement’s results panel. The specified line numbers for the selected measurement is displayed in the Line Number field
in the corresponding results panel. When the Run Mode is set to Once & Report, the instrument generates a report file in the
selected format (RTF, PDF or CSV), that contains the results for all of the individual line numbers in the selected range,
followed by the averaged results calculated for the whole range.
