Input Connection Requirements – Options SD/HD
Use only 75 Ωcoaxial cables to connect the video device under test to the VM5000 instrument.
Install the included 75 Ωterminations
between the end of the coaxial cables
and the instrument input channels, using
the included BNC T connectors. To
achieve accurate frequency response
measurements, it is important to attach the
T connectors directly to the input channel
BNCs.
Input Connection Requirements – Option VGA
The preferred method of connecting the video
device under test to the VM5000 instrument
is to use the RGBHV Measurement Interface
Unit. The Measurement Interface Unit
contains an impedance-matching circuit
to ensure accurate measurement results.
For some measurements, a low-frequency
path is used and for other measurements a
wideband path is used. The VM5000 selects
which path is used through an RS-232
connection to the Measurement Interface
Unit.
You can also connect the video device under
test to the VM5000 by using the supplied
VGA connector to 5X cable. If you use
this method, you will need to connect the
cable to the VM5000 using the supplied
precision terminations and you may need
to manually change terminations while
taking measurements, depending on which
measurements you take.
VM5000 Quick Start User Manual 7

Getting Acquainted with Your Instrument
Connecting Input Signals
Option SD/HD Setup 1
Setup 1 is the preferred setup for testing 3-wire component analog video signals (Y/G, Pb/B, Pr/R) with the composite
sync signal on Y/G. This setup uses 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, the 75 Ωtermination should be connected as close to
the input connector as possible, as shown in the setup illustration.
8VM5000 Quick Start User Manual

Getting AcquaintedwithYourInstrument
The following illustration shows how to connect the Sync Pickoff to the CH1 input.
NOTE. Verify that the trigger channel is set to channel 4 (the default setting). If the trigger setting (Configuration > Operation)
is not set to CH4, you will see signal warning messages and be unable to take measurements.
Option SD/HD Setup 2 - Three-Wire Analog Video with Composite Sync
Use this setup for testing 3-wire component analog video signals (Y/G, Pb/B, Pr/R) with the composite sync signal on Y/G.
Set the triggering on the instrument to channel 1 (the default trigger setting is CH4). This setup is simpler than the others
mentioned in this section, but limits noise measurement on Y/G to -65 dB (30 MHz noise bandwidth).
