Instrument Tests

SDI Input Equalization
Range
48
Requirements
At least 3 ½ digits, 0.1% or better
DC voltage measurement accuracy at
700 mV.
>3 GHz bandwidth with 75 Ω input,
>20 dB input return loss to 3 GHz, ±3.5%
or better vertical gain accuracy.
NOTE.
Use a DVI-A adapter if you are connecting to an XGA monitor with a
15-pin RGBHV analog interface.
Use the following setup for all tests unless otherwise specified.
1. Connect the power cord to the rear of the waveform monitor.
2. Connect an XGA monitor to rear of instrument.
3. Connect the power cord to the AC mains and allow at least 20 minutes for the
waveform monitor to warm up before beginning any procedures.
The following procedures apply to all base instruments except where labeled for
specific models. Do all tests except those that exclude your model.
Connect the power cord to the AC mains and allow at least 20 minutes for the
waveform monitor to warm up before beginning any procedure.
This test uses a cable clone to simulate cable. This verifies that the waveform
monitor can receive signals that have passed through long cables.
All models have an SDI interface with four inputs. Each SDI input should be
checked.
270 Mb/s checks.
1. Set the waveform monitor to the factory presets. (See page 32, Restore the
Factory Presets.)
2. Connect the TG700 DVG7 SIGNAL 1 output to the SDI 1A input.
NOTE.
All signal connections are made with 75 Ω digital video coaxial cables.
