Possible Errors and Troubleshooting Tips. If there is any problem associated with

the MIU or its connections, the following error message appears:

Error occurred in configuring the MIU

Perform the following steps to isolate the problem:

1. To further localize the problem, check the results display. For example, if there is no signal on the G channel, the corresponding results will not be displayed. So, check the G channel cables and their connection at the input side of the MIU. Between the MIU and VM Series System check the Ch 1 cable and its connections.

2. If expected results still do not appear, there might be some internal problem in the MIU.

3. Other warning messages can be due to an incorrect signal or no signal. If the warning is due to no signal, carry out the checks specified in step 1 above. If the warning is due to an incorrect signal, ensure that the VGA card is set to the same resolution, refresh rate, and timing standard as selected in the Format panel of the application and that the appropriate BMP file is used.

This completes the VM Series functional test for Option VGA. If your VM Series System did not complete the functional test satisfactorily, contact your local Tektronix Service representative.

Operating Basics

This section provides basic information on how to use the VM Series System. More detailed measurement information can be found in the Reference section.

Input Signal Connection Requirements

Option SD/HD

Use only 75 Ω coaxial cables to connect the video device under test to the instrument.

Install the included 75

Ω terminations between the end of the coaxial cables and

the instrument input channels, using the included BNC “T” connectors. See Figure 2--1. For accurate frequency response measurements, it is important to attach the “T” connector directly to the input channel BNCs.

Option VGA

The preferred method of connecting the video device under test to the instrument is to use the RGBHV Measurement Interface Unit. The Measurement Interface Unit contains an impedance-matching circuit to ensure the most accurate measurement results. For some measurements, a low-frequency path is used and for other measurements a wideband path is used.

VM Series Video Measurement System User Manual

2- 1

Operating Basics

The VM Series System selects which path is used through an RS -232 connection to the Measurement Interface Unit. See Figure 2--2.

Figure 2- 2: RGBHV Measurement Interface Unit

You can also connect the video device under test to the VM Series System by using the supplied VGA Connector to 5X cable. See Figure 2--3. If you use this method, you will need to connect the cable to the VM S eries System using the supplied precision terminations. Depending on which measurements you take, you may need to manually change terminations while taking measurements.

SD/HD)

Setups 1A and 1B are the preferred setups for testing 3-wire component analog video signals (Y/G, Pb/B, Pr/R) with the composite sync signal on Y/G. These setups use the sync pickoff accessory to derive the trigger signal from the Y/G signal on CH1. The triggering source is set to Channel 4. This configuration provides more accurate low-level noise measurements (below --60 dB at 30 MHz bandwidth) than setup 2.

This type of connection allows you to make more accurate noise measurements on CH1 while triggering on CH4, without adding additional cabling between CH1 and CH4. The additional cabling could adversely impact frequency response and multiburst measurements.

To achieve the best frequency response and multiburst measurements, the75 termination should be connected as close to the input connector as possible, as shown in the setup illustration.

There are two ways to connect the Sync Pickoff to the VM Series System. One way connects the Sync Pickoff directly to the input and the other way connects through a T-connector attached to a 75 Ω termination. If you are using a 012--1680--01 Sync Pickoff (contains internal 75 Ω termination), connect the Sync Pickoff directly to the VM Series System CH1 input (using a TPA-BNC adapter) as shown in the following Figure 2--4. If you are using a 012--1680--00 Sync Pickoff (requires external 75 Ω termination), use the Figure 2--6 shown in Setup 1B.

H CVT--R: The Coordinated Video Timing Reduced Blanking standard is for

use with non--CRT displays that can accept reduced horizontal blanking times.

H GTF: The Generalized Timing Formula standard is a method for generating

general purpose display timings and new formats. This allows much greater flexibility in the choice of refresh rates and pixel formats than currently available with discrete monitor timings. GTF enables new formats and refresh rates to be developed, but is based on some set parameters to improve the likelihood of interchange.

Setup & Run: Configures the instrument setting and takes a measurement, for each selected

measurement, and for each measurement acquisition. Use this when taking multiple measurements that require different instrument setups.

Setup Only: Configures the instrument for a measurement but does not take the measurement. Use

this to set up customized settings. Try out your settings by pressing the R un button, making adjustments as needed (for example, change the horizontal scale), and then pressing the Run button again. Once you are satisfied with your customization, use the Run Only setting to collect results. Setup Only is not selectable for certain measurements like H Sync, V Sync, Noise Inj Ratio, V Timing, and Video Transient as they need multiple settings for the oscilloscope and MIU.

Run Only: Takes a measurement using the existing instrument configuration. Designed for taking

measurements with custom settings (see the Setup Only description above).

5. Auto Scale fits the signal within the available vertical scale. Auto Scaling adjusts the vertical scale units so that the input signals fill the graticule as much as possible. Auto Scaling occurs once for each selected measurement. Select the Enabled check box to enable waveform Auto Scale. Clear the Enabled check box to disable waveform autoscaling.

In the initial values pane, there are three settings: Last Meas, Last Recalled, and Restore Default.

Last Meas.: is the default. When selected, the values from the last measurement will be used at the

start of the next Auto Scale step.

Last Recalled: when selected, the values recalled with the last recalled setup will be used at the

start of the next Auto Scale step. If a setup (File > Recall Setup) has not been recalled since the program was started, the application will load the Auto Scale settings from the last power up.

Restore Default: when selected, the Factory Default Auto Scale starting points will be used at the

start of the next Auto Scale step. See page 3--8 for details.

NOTE. If you take measurements on the wrong line or with the wrong scale setup, press the Restore Default button before taking measurements again.

Single Line takes each selected measurement on the line specified in the Line Number field of the

Results window.

Multi Lines takes each selected measurement across a range of lines. You acquire measurements

across multiple lines by specifying the starting and the ending line numbers. When Multi Lines is selected, the Generate Report button in the Utilities > Generate Report panel is not selectable. When Multi Lines is selected, the Run Mode operation settings Once and Once & Report are selectable and the report is generated based on the configuration set in the Utilities > Generate Report.

8. (Option VGA) Select Use MIU to automatically route H and V signals to the CH4 output depending on the selected measurements.

9. (Option VGA) The specified polarities for the H Sync and V Sync signals vary between the timing standards.

In the absence of the MIU and with Auto Detect selected, the VM Series will prompt you to connect the H Sync and V Sync signals to determine the polarities. If you use the MIU, the VM Series will automatically determine the H Sync and V Sync polarities.

Once the sync signal polarities are determined, the measurement cycle begins. This “polarity test” is performed at the beginning of every measurement cycle. To prevent this test from running at the beginning of every measurement cycle, take any measurement once with Auto Detect selected. Once a measurement cycle has been completed with Auto Detect selected, you can clear Auto Detect.

The VM Series remembers the polarity of the sync signals. Any time you change the format setup for the device-under-test, you should complete a measurement with Auto Detect selected.
