Preface

viii Waveform Rasterizers Speciﬁcations and Performance Veriﬁcation

Speciﬁcations

This chapter contains speciﬁcations for the Tektronix WVR6020, WVR7020, and WVR7120 waveform rasterizers. Items listed in the Performance Requirement column are ge

nerally quantitative, and are either tested by the Performance

Ver i ﬁcation procedure or are guaranteed by design.

Items listed in the Reference Information column are useful operating parameters that have typical values; information in this column is not guaranteed.

The speciﬁcations listed in the Electrical Speciﬁcations portion of these tables apply over an ambient temperature range of +0 °C to +50 °C. The rated accuracies are valid when the instrument is calibrated in an ambient temperature range of +20 °C to +30 °C and has been operating continuously for at least 20 minutes within this range.

The characteristics are divided into the following sections:

Incoming Inspection

This section contains functional a nd operational checks appropriate to an incoming inspection.

The waveform rasterizer must have been operating for a warm-up period of at least 20 minutes, and must be operating at an ambient temperature as listed in the table. (

Use the following procedures to check the basic functionality of WVR6020, WVR7020, a model and option so that you can choose the sections that are appropriate for your instrument. The last two sections are for less critical waveform rasterizer features: the ground closure and Ethernet ports. You need only test these if you intend to use them. In general, you should test in the order presented, since later tests might depend on items checked in the earlier tests.

1. Connect a XGA mo

rasterizer.

2. Connect the AC

240 VAC source. There is no power switch on the waveform rasterizer, so the instrument will turn on as soon as you apply power.

3. Look at the front panel immediately after you apply power. All the buttons

should be lit, the text above the three knobs should also be lit, and the FAULT indicator

4. After a couple of seconds, the lights in the buttons and text will turn off.

5. After about 15 seconds, the FAULT light should turn off. Record Pass or

Fail in the test record.

6. Also after about 15 seconds, the Power on diagnostic page should appear

on the XGA monitor.

2. Connect a 525/270 color bar signal from DVG1 to the SDI A input.

3. Attach a loopthrough terminator.

4. Press the FULL button to set the active tile to full screen.

5. Turn the HORIZONTAL and VERTICAL knobs and verify the waveform

moves appropriately.

6. Press HELP to display the online help.

7. Press each of the front panel buttons.

Each button should ﬂash as you press it. Most buttons will bring up help text related to that button in the right pane of the help screen. Some buttons, such as the presets, all bring up the same information, so you may need to alternate between preset buttons and another button to see the text change. The navigation keys (the four arrow keys and the SEL key) do not bring up help text. They are used to navigate the help panes and content.

Signal Source Characterization for Eye Signal Bandwidth

Ver i ﬁying eye signal bandwidth requires a 75 Ω RF sine wave signal that can be connected to the 75 (Ω) BNC input, and is either characterized or automatically leveled. (See page 90.). The results of characterization must be applied at each measurem applying a correction to the amplitude reading from the unit under test.

The meth appropriate adapters and cables to connect to the 75 Ω female BNC input of the unit under test. The exact sequence of adapters, min-loss pad, and cables is not critical if correct impedance is maintained in each section, and if the complete setup is used exactly as characterized when measuring Eye bandwidth.

The absolute signal level should be chosen to give between 750 and 850 mV at the reference frequency, as viewed on the unit under test when in Eye BW check mode. With a setup consisting of a 50 Ω generator, a 5.7 dB min loss pad and a gives this result.

The two sources are set to different rates to allow transitions of the serial signal to hit all possible phases. If the isolation is sufﬁcient, the cross-talk will not introduce errors.
