`DSA 1491– User Manual
Section 7: Audio/Video In/Out Monitoring
The DSA 1491 offers several A/V input and output features which supplement its TV-RF
analyzing capabilities. This section summarizes the audio/video input and output
features and provides operational information.
7.1 HDMI Output Monitor – Using an External HDMI Monitor
The DSA 1491 includes an HDMI Output which may be connected to a display equipped
with an HDMI Input. The HDMI display, when connected to the DSA 1491's HDMI
Output, may be selected and used to display all of the test screens normally seen on the
DSA1490 and be used to monitor the audio. The HDMI display may be used to monitor
satellite or TV-RF signal measurements, constellation measurement, spectrum analyzer
analysis, MPEG services, and program video. Using a larger HDMI monitor can greatly
enhance monitoring for satellite and broadcast applications.
When the display video is switched to the HDMI monitor, the display screen on the DSA
1491 goes blank. It is not possible to show simultaneous video on an external HDMI
display and on the DSA 1491 simultaneously.

When the DSA 1491 viewing screen is being viewed with an external monitor, selecting
tests and navigating remains the same as the touch screen on the meter is active.
However, without a physical position reference, touching the screen to select desired
fields becomes challenging.
When using an external video monitor, it is advisable to use the touch Control Knob at
the upper right of the meter. While a bit more difficult compared to touching the screen,
the Control Knob and touch front panel pushbuttons provide full navigation and
selection. Some practice may be needed as you shift your interface technique from
touching the screen to Control Knob use.
